Beginner’s Setup Guide for Growing Indoors

Growing indoors provides several advantages over outdoor growing. It allows you to have more control over your crop in terms of lighting, temperature, humidity, etc., as well as gives you greater predictability in your yield. Indoor growing also allows for year round growing which means more harvests.

When setting up your grow space there are several factors that you need to take into consideration. You will need to dedicate a space and create a controlled environment for your cannabis plants complete with proper grow lights and ventilation. In addition, you will need pots or trays for your plants to grow in as well as nutrients and soil. Many growers choose to purchase equipment for when it comes time to harvest such as bud trimmers. There are a number of additional accessories that are available to growers as well. For example timers and controls to monitor your system can be very beneficial and allow you more freedom.

In this guide we will take a closer look at what exactly is needed to create your cannabis growing setup. We will go through step by step and delve into more detail about what it takes to successfully grow cannabis indoors. Included are several lists of recommended products for each step as well.

Grow Space

Indoor growers typically grow in one of three places, depending on the scale of the operation. Large scale growers can often dedicate a whole warehouse sized space to their cannabis plants. Smaller scale growers usually have either a small room or a grow tent.

There is no right or wrong sized space when it comes to growing cannabis. However the size of your grow space will play a significant role in how many plants you are able to house. Regardless of the size of your grow space, it will still need to be a controlled environment.

The equipment you purchase will vary slightly depending on the size of your grow space as well. Take grow lights for example. Lights with higher wattage are typically able to cover more square feet of grow space. So if you have a large warehouse you will need several higher watt lights in order to cover your cannabis plants. On the other hand, if you only have a small grow tent you should be able to get by with only one or two lower watt lights.

The same goes for ventilation. There are several companies who specialize in industrial sized fans made to circulate air in large spaces. There are also models that are more suited for small rooms.

These are just some of the things to keep in mind when determining the size of your grow space. If you have any plans of growing your operations in the near future, it may be wise to invest in a larger space to begin with. That way you’ll already have the space and equipment needed when your crop is larger.

If you are only planning to have a small number of cannabis plants, perhaps you’re only growing for personal consumption, it will probably be in your best interest to purchase a grow tent. Grow tents are handy little contraptions that create a controlled environment that can be placed virtually anywhere. They are typically made of a heavy duty, tear proof, lightproof and waterproof material such as vinyl or oxford cloth. Good grow tents also have a reflective inner lining, usually made of mylar. Most have built in mesh vents and openings for grow lights, power cords and fans. They come in a variety of sizes, suitable for any small scale grower.

Starting from Scratch

If you are planning to start your plants from seeds rather than clones, there are a few things to keep in mind. First, you will need to germinate your seeds in order to successfully grow them into live cannabis plants. There are five main methods of germination which are discussed more in detail below.

Method One: Paper Towel

This is a popular method among new growers, because it is relatively simple to do and requires no additional equipment beyond what you probably already have in your home. The only disadvantage to this method is that it’s easy to damage the tap root while moving the seeds to their growing medium. The tap root is the little white root that grows out of the seeds after germination.

To use this method you will need two paper plates and paper towels in addition to your seeds.

Begin by placing a moistened paper towel on one of the paper plates. Spread your seeds evenly over half of the paper towel and fold the other half over on top of the seeds. Cover the paper towel with the other paper plate to lock more of the moisture in.

Check your seeds regularly to see if they have sprouted. Seeds can take anywhere from one day to upwards of a week depending on how old the seeds are. Make sure you are very careful when moving the paper towel so as to not damage the tap roots.

Always make sure the paper towel is still moist. Use a spray bottle and spray the paper towel if it starts to dry out. Remember, the towel should be damp, not soaking wet.

Once the seeds have sprouted, carefully transfer them to the growing medium.

Method Two: Starter Cubes/Seedling Plugs

This method tends to be the most favorable for growers, as it is nearly impossible to mess up. Cannabis seeds can be expensive as some seeds have highly sought after genetics, so this fool-proof method is very popular. There are many reputable companies that create these starter cubes and seedling plugs.

Using starter cubes and seedling plugs is fairly easy. You will easily be able to see the opening for the seed in the plug or cube. Simply place the seed in cube or plug, pinch the top shut, water as directed and the seeds will germinate on their own. The advantage of using cubes and plugs is that from the moment the seeds are placed in the plugs, they will be exposed to the perfect environmental conditions for germination.

Here are two of the best starter cubes and seedling plugs.

1. Rapid Rooter 50 Pack

Rapid Rooters are manufactured by General Hydroponics, which is a highly trusted company known for their quality products. Rapid Rooters come fortified with micro-nutrients that stimulate root growth. They have some of the best germination rates of any product and method. After the seeds have germinated, these plugs can be placed directly in your growing medium. By using these plugs you won’t have to touch the seeds beyond initially placing them in the plugs. This will help prevent damage to the tap roots and root shock.

You can buy Rapid Rooters in the form of a 50-pack of individual seedling plugs or as a 50 cell tray with plugs already in place.

2. Jiffy Peat Pellets

Another popular form of seedling plugs are peat pellets. These pellets are similar to Rapid Rooters, however they cannot be used hydroponically. To use Jiffy Peat Pellets, you must first soak them in warm water so they expand to the proper size. Gently squeeze out any excess water and then use them the same as Rapid Rooters.

Using these pellets will also help to prevent root shock when transplanting as you can plant this directly into your growing medium. Jiffy Peat Pellets are advertised to produce faster germination which can help reduce the total grow cycle length by up to 25 percent. This can be helpful for growers who are looking to turn their cannabis crop as quickly as possible.

Jiffy Peat Pellets can be bought in a multitude of sized packs as well as various sized trays.

Method Three: Germination Stations

Germination stations are typically used in conjunction with starter cubes or seedling plugs. They help to create an ideal germination environment. There are several commercial germination stations available, though you can make one yourself as well.

To make your own germination station you will need your cannabis seeds, starter cubes like the aforementioned Rapid Rooters, a plate, a plastic dome and a heating pad. Position your plate over the heating pad and place your starter cubes on the plate. Put the plastic dome over the plate to lock in the moisture and heat.

If you’d prefer a commercial product specifically designed for germinating seeds, check out the following products.

1. Jump Start CK64050

This station is 72 cells and comes with a 17 watt, waterproof heating pad. The base tray is watertight as well, which helps to reduce mess. The plastic dome locks in humidity and moisture, which is essential for your seeds to germinate successfully. The station also features adjustable vents on the top and ends. Use your preferred seedling plugs or starter cubes with this station.

2. VIVOSUN 10″x 20″ Germination Kit

This station also features 72 cells. The heating pad is controlled by a thermostat and can be set to temperatures ranging from 68-108℉ or 20-42℃, depending on the crop’s specific needs. Research the cannabis strain that your growing and see what temperature the seeds tend to thrive at. Most cannabis strains prefer temperatures around 78℉ or 26℃. The adjustable thermostat is a great feature that most other germination stations do not offer. The dome also has two vents on the top that can be opened or closed. Another advantage of this station is that the heating pad is heated by inner heating wires, so it cannot catch fire. This allows the seeds to be left alone virtually risk free.

Method Four: Plant Directly into Growing Medium

This method is as easy as it sounds. You simply plant your seeds directly into the soil or similar medium. Many growers like this method because it mimics how the seeds would grow naturally.

This method is also good because you eliminate the risk of root shock when transporting your germinated seeds to the growing medium like in the paper towel method. Anytime you transplant a sprouted seed, the seed has to readjust to its new environment which can cause stress. However, this method does not have as high of successful germination rates as using seedling plugs or starter cubes.

To plant your seeds directly into soil or another similar medium, measure about 0.5-1in or 1.3-2.5cm into the soil and place your seed in the pocket. Make sure the soil is kept moist, but not soaking wet. Using a light or heating pad to keep the area warm can help increase germination success rates.

Method Five: Soak Seeds in Water Overnight

This method is great for cannabis seeds with particularly hard shell as well as older seeds. The method is simple. All you will need is a glass of lukewarm water and your seeds. Simply place your seeds in the water and soak them overnight.

All seeds will start out floating, but the viable seeds will sink after soaking for a few hours. By the next day you should see the tap roots start to emerge from the seeds. It can be beneficial to use a clear glass so you can see when the tap roots appear.

Some seeds can take longer than others to sprout, but don’t leave the seeds soaking for longer than 24-32 hours. Any longer than this and the seeds can drown. After 24 hours, any seeds that haven’t sprouted yet can be transferred to another suitable place to finish germinating if you so choose.

How do I know if my seeds are good?
You can generally tell if your seeds will germinate by the color of them. White and green seeds are typically not viable. Darker seeds are your best bet for successful germination.

You may have heard of the method of testing seeds for their viability by seeing if you can crush them or not between two fingers. This has been disproven. As long as the seed is darker in color, it has the potential to germinate. Even if a seed appears flimsy or weak, you should still try to germinate it as it will likely be successful.

Grow Mediums

Once your seeds have sprouted, you should plant them right away. If you used the paper plate or water soaking methods, then your seeds will be exposed and you need to take extra precaution when moving them. Avoid touching the tap root to avoid any damage or potential breaking of the root. It can be helpful to use a tweezers to move the seeds to your growing medium.

Cannabis growers typically choose one of three growing mediums: soil, soilless mix or a hydroponic system.


There are a number of soil mixes available for growers to use. If possible, using an organic and composted mix for the best results. Keep in mind that you will likely have to add additional nutrients to your soil in order to ensure your cannabis plants will grow successfully. You can also create your own compost mix, creating a sort of “super soil”. These take a little longer to produce, so you will have to plan ahead.

When selecting a soil mix, look for organic mixes. Steer clear of any soil mixes that have time-release nutrients such as MiracleGro. Also, do not place your grow lights at full strength over your seedlings as this can impede growth. Be mindful when watering as well, as seedlings can easily be overwatered and drown. Keep in mind that cannabis seedlings thrive in a pH around 6, so look for a soil mix that is as close to that pH as possible.

The following products are great soil mixes for your cannabis seedlings.

1. FoxFarm FX14000 Ocean Forest Organic Soil

This mix is great for cannabis plants. It’s ready to use right out of the bag and contains all the nutrients your seedlings will need for the first month of their lives. This soil mix contains micronutrients, bat guano and earthworm castings, all of which will help your cannabis seedlings grow faster and healthier. Ocean Forest has a light texture and is well aerated making it ideal for containerized plantings, which is how most growers choose to grow their cannabis plants.

2. FoxFarm FX14082 Happy Frog Soil

This mix is another great option for cannabis plants. It is also ready to use right out of the bag. Happy Frog is a live soil, and contains beneficial soil microbes as well as mycorrhizal fungi. These added nutrients help to expand root development by allowing the plants to feed more ‘aggressively’. This mix is pH adjusted to allow premium absorption of nutrients. It is also ideal for containerized plantings, similar to Ocean Forest. Happy frog is advertised to promote exceptionally strong plants, rapid growth and enhance flowering. These are all crucial aspects when growing cannabis plants.

Soilless Mix

Soilless mixes are technically considered to be a semi-hydroponic technique. There are several soilless mixes on the market that are a great alternative to traditional soil. These mixes are typically much lighter than soil, so they give your cannabis plant roots better access to air and nutrients which results in faster growth. They also tend to drain much better, so it’s harder to overwater your cannabis plants.

Compiled below are some of the best soilless mixes on the market.

1. General Hydroponics CocoTek (Coco Coir)

CocoTek is made out of three types of coco coir, which is ground up coconut husks. It is a wonderful, sustainable and eco-friendly alternative to traditional soil mixes. Generally speaking, you will be able to get bigger plants with smaller pots by using CocoTek, because the material is much lighter so the plants will have better access to air and nutrients.

Another advantage of CocoTek is that it is nearly impossible to overwater your cannabis plants when planted in this mix. Even when completely saturated, CocoTek retains a roughly 70:30 moisture to aeration ratio. This means the roots will never sit in stale water. However, CocoTek can dry out easier so you need to make sure you water regularly and monitor its moisture content.

CocoTek can also help produce higher yield quantities. In fact, it has been shown that using coco coir can increase your overall yields by up to 25 percent. CocoTek is also reusable. After you harvest your plants, you can flush the material and use it again.

2. Hoffman 16504 Horticultural Perlite

Perlite is the product of volcanic cooling. It allows for air spaces which let the oxygen and water move more freely about the container, in turn stimulating root growth. Hoffman’s Horticultural Perlite is advertised as a lightweight soil conditioner. That means it can be mixed with other soilless alternatives to create your own custom mix. This mix helps to improve drainage and aeration, both which your cannabis plants need plenty of to grow successfully. Because it is a completely natural product, it won’t disrupt the pH level your plants require.

3. Espoma VM8 Organic Vermiculite

Vermiculite is a hydrous phyllosilicate mineral. It is similar to perlite in that it is mineral based. Vermiculite is lightweight and helps to prevent caking when used in a custom soilless mix. It helps to aerate the soil, which stimulates root growth. Vermiculite is also highly absorbent, which is great for moisture loving plants like cannabis. This mix also does not break down easily, so it acts as a permanent conditioner. Vermiculite does have a slightly higher pH, typically around 7. This means that you will need to adjust the pH levels to get it back down to optimum cannabis growing pH.

Hydroponic System

Hydroponic systems do not use soil to grow the cannabis plants. Instead they grow the plants in a water based solution that is rich in nutrients. By not using a soil or other medium, the plants come in direct contact with the nutrients. This helps to stimulate growth and increases yields.

In fact, by using a hydroponic system, your cannabis plants will mature up to 25 percent faster and increase your harvest yields by up to 30 percent when compared to plants grown in soil. The reason behind this is because the cannabis plants will not have to work as hard to obtain the nutrients, so they are able to redirect that energy into growing and producing.

There are several types of hydroponic systems, so it’s important to research which method will work best for your set up. Remember that hydroponic systems take a slightly larger initial investment, though the increased yield will likely make it worth it. Hydroponic systems are also a little more difficult to set up and manage, so most beginner growers tend to start out with one of the other mediums before making the transition into hydroponics. However, many beginner growers have had great success with starting out in hydroponics. As long as you do the proper research, you will be able to make the best decision for your individual cannabis operation.


There is a lot of conflicting information about which nutrients to give your cannabis plants. Many different companies sell various mixes, all which promise the same thing: to grow your plants faster and produce higher yields. However, if all the nutrient combinations are different, then how do they all do the same thing?

The answer is much simpler than it may seem. When choosing the right nutrients for your cannabis plants, simply do the research on what nutrients are right for which phases of plant growth. This will help make your decision more informed and easier.

There are two main phases of plant growth for cannabis plants: vegetative and flowering. The most important nutrients for your plants are Nitrogen, Phosphorus and Potassium. Oftentimes you will find the ratios of these nutrients being referred to as NPK or three numbers in the “N-P-K” format. For the vegetative phase, your cannabis plants will need high levels of Nitrogen, medium levels of Phosphorous and high levels of Potassium. For the flowering phase on the other hand, your plants will need low levels of Nitrogen, medium to high levels of Phosphorous and high levels of Potassium.

Common vegetative phase ratios:
• 3-2-4
• 9-3-6

Both of these ratios are good as there is plenty of Nitrogen, which is the most important nutrient for cannabis plants in the vegetative phase of plant growth.

As your plants transition to the flowering phase, you should continue giving them vegetative nutrients. The reason why is that your cannabis plants will need plenty of Nitrogen to produce the new leaves and stems. Once your plants have fully entered the flowering stage, you can switch to flowering nutrients.

When looking for flowering nutrients, you will want at least double the Potassium as Nitrogen. This is because after the transition period, the plants stop using the Nitrogen and switch to mostly using Phosphorous and Potassium.

Common flowering phase ratios:
• 2-7-7
• 2-3-5
• 5-15-14

Different companies also produce nutrient mixes for different grow mediums. This is important when selecting your nutrients. Also keep in mind that many nutrient mixes aren’t necessarily one for the vegetative phase and one for the flowering phase. Rather, they are three separate bottles with different ratios and include a nutrient schedule to follow.

Compiled below are two of the best nutrient mixes for use in the various aforementioned grow mediums.

1. General Hydroponics Flora Trio

This nutrient system is advertised as the original “building block nutrient system”. It contains primary, secondary and micronutrients that will produce higher yields and better overall quality of your cannabis crop. The concentrates are also highly purified, which allows for better solubility. The system is also pH balanced for greater ease in using it.

The system contain a nutrient schedule for users to follow on the back of the bottles. This particular system is suited for use in hydroponic and soil grow mediums, though not in soilless mixes.

2. FoxFarm FX14050 Liquid Fertilizer Nutrient Trio Hydro-Formula

This system is made easy for users as each bottle is formulated for different things. The ‘Grow Big’ bottle is made for cannabis plants in the vegetative stage. ‘Tiger Bloom’ is to be used at the first sign of budding/flowering. ‘Big Bloom’ can be used throughout both stages to help heal and strengthen the root systems and increase nutrient cycling.

This nutrient system is only suitable for hydroponic and soil-less grow mediums.


Another important thing to keep in mind is the pH of your water. You will want to maintain the overall pH of your grow medium around 6, as mentioned previously. Different mediums allow for different pH ranges that will still allow your cannabis plants to grow properly. If you’re using soil, a pH between 6 and 7 is ideal. If you are using a soilless mix, generally you will want a pH between 5.5 and 6.5. Hydroponics also require a pH between 5.5. and 6.5.

Different grow mediums will call for different watering methods. For example, soilless mixes tend to retain water longer, so watering won’t need to be as often. While you are figuring out the right watering schedule for your plants, take into account the appearance of your plants. You will be able to tell if they need more or less water by looking at several factors.

Under-watered plants will look droopy and weak. Over-watered plants will look similar, though the tips of the leaves will actually start to curl. This is the plants way of trying to ‘hide’ from the excess water in its environment. Another good way to determine if it’s time to water your cannabis plants is by checking the soil. Stick your finger all the way into the soil. If it is completely dry it is time to water your plants.

Your cannabis plants need a cycle of wet and dry in order for the roots to grow stronger and deeper. Ideally, you should monitor your plants and determine what they look like right before they appear under-watered. Eventually, you will be able to spot this and water right before they start to appear less vibrant.

Another important thing to keep in mind is the size of your grow containers. If your plant’s roots are not long enough to reach the bottom of the container, then it won’t be able to absorb all the water you provide. On the other hand, if your container is too small then it may stunt the plant’s growth and develop nutrient deficiencies.

When you water your plants you should water long enough to soak the pot and have a slight amount of run off. If you are unsure if you have watered enough, simply water a little at a time. Wait for the water to soak into the mix and water a little more. If the water sits on the top of the mix and does not soak in, then you have watered too much.

Play around a little bit with watering your plants and find a schedule that suits your individual schedule and your plants’ needs. Typically you will find yourself watering your plants every two to three days. Remember that even cannabis plants can withstand slight over and under-watering so don’t stress out too much if it takes you a few watering cycles to figure out what works best.

Grow Lights

Grow lights are another crucial component of a successful indoor cannabis growing setup. When choosing your grow light(s), it’s important to remember there is no such thing as a one-size-fits-all light. Different sized setups will need different lights, so you have to find the one that will work best for you and your cannabis plants.

Types of Lights

There are several types of grow lights to choose from, all with their individual advantages and disadvantages. Different types of grow lights include fluorescents, HIDs and LEDs. In this guide we will focus on LED lights, as they offer the most advantages and options for successfully growing cannabis.

What are LEDs?

LED stands for Light Emitting Diode. LEDs are designed to mimic natural sunlight, which makes them the most natural way for your cannabis plants to grow indoors. Within LEDs, there are a few different options. Some LED lights are made specifically for one phase of plant growth. If you are planning to grow your cannabis plants from seed to flower, you will need a full-spectrum light.

Full-spectrum LEDs contain red, white and blue light spectrums so they are suitable for all phases of growth. Many will also have different settings depending on the different phases. Some LED lights are single channel, meaning they are either on or off. Other lights are two channel, which means they have both a vegetative and flowering mode. Finally, there are fully programmable lights which can conform to your individual lighting schedules and typically have the ability to create custom spectra. These lights also usually have the ability to have the intensity of the light modified as well.

Advantages of Full-Spectrum LED lights
• Because full-spectrum LED lights contain several light spectrums and are suitable for every phase of plant growth, you can rest assured that your plants will receive exactly the light they need at all times.
• Full-spectrum LEDs encourage larger product yields.
• These lights last for years. Some have been known to last up to 50,000 hours or more.
• Full-spectrum LEDs are the most energy efficient of all grow lights, using up to 70 percent less electricity.
• They emit less heat, which eliminates the need for extra fans. In fact, even after 24 hours of run-time, LEDs will still be cool to the touch.

Things to Keep in Mind
It’s important to remember that LED lights never run at full power, which is why they have such a long lifespan. For example, one 3-watt chip will only run at about 60 percent of its full power. So when you’re looking at lights, remember that most manufacturers will list the full potential power of the light, not what it actually produces.

Take a typical 600 watt light for example. This light would typically be comprised of 200 3-watt chips or possibly 120 5-watt chips. However, because the chips only emit 60 percent of their full capacity, the actual wattage is more like 300-400.

For this reason, it will be in your best interest to buy a higher wattage light. If you buy a higher wattage light, you won’t have to worry about your cannabis plants not getting enough light. Plus, chips will inevitably burn out. Therefore, your lights will last longer because they will be able to compensate for any wattage lost.

Don’t purchase a light with chips under 3 watts. Any chips smaller than this will prevent your plants from receiving full coverage.

Light Cycles for Different Phases

Your cannabis plants will need different lighting cycles dependent on what phase of plant growth they are in. For the vegetative stage, a typical light cycle will be 18 hours on and 6 hours off. This pattern mimics the standard daylight cycle. Some growers prefer to have their lights on 24 hours a day because that can help stimulate plant growth and cause the cannabis plants to move on to the flowering stage faster. It’s completely up to you which cycle you prefer for your vegetative stage. Some growers have found that the standard daylight cycle is better when compared to 24 hours of light for indica strains. Also, cannabis plants in the vegetative stage need about half the wattage as plants in the flowering stage. This allows you to position your grow lights higher above the plants, creating a larger coverage area.

Once your cannabis plants begin to show signs of entering the flowering stage you will need to switch your light cycle to 12 hours on and 12 hours off. This will encourage the plants to leave the vegetative stage and to start producing buds. Depending on the strain of your plants, they make take more or less time than others to mature. If you know which strain your cannabis plants are, it may be helpful to look up the average height of the plants when they are grown indoors. This will be helpful in determining when they are ready to leave the vegetative stage and enter the flowering stage.

Below are five of the best full-spectrum lights currently available.

1. Apollo Horticulture GL60LED Full Spectrum 180W LED Grow Light

Ventilation & Odor Control

Proper ventilation is very important regardless of the size of your grow space. Air flow is crucial in allowing your cannabis plants to grow to their full potential. Depending on what type of grow light you choose, the lights can emit significant amounts of heat and damage your plants. You should actively monitor the temperature in your grow space because the addition of fans can cause the temperature can drop too low which is just as dangerous for your plants.

Inline fans are a great solution to your ventilation needs. They require little to no additional equipment as the can usually be attached to existing ducting. Inline fans are also the most cost effective and energy efficient ventilation option.

The inline fan that will best fit your set up depends on the size of your grow space. The basic formula for calculating what inline fan you will require is: length x width x height x 20 = total volume of air per hour needed. Volume of air, otherwise known as airflow, is calculated in CFM or cubic feet per minute. So when looking at inline fans, look for a rating that matches your calculation. For example, if your grow space is roughly 10 cubic feet then you will need a fan with at least 200 CPM.

Larger grow spaces such as commercial size warehouses will need more than one fan. Most inline fans are adjustable, which allow you to control exactly how much air is moved per hour. Some units include this feature built in or have a separate compatible component available for purchase.
Depending where you live, you may also need to neutralize the odor of the air as it is circulated out of your grow space. A carbon filter will solve this problem. These handy devices attach directly to inline fans and filter the air as it is circulated out of the environment while simultaneously removing any lingering odors of cannabis. Ionizers are also great to have on hand, should you need to eliminate the smell of your plants very quickly.

Here are five of the best inline grow fans available on the current market.

Harvesting, Trimming & Curing the Buds


Figuring out when to harvest your buds can be confusing. One good rule of thumb is too observe the little hairs that are growing out of your buds. They start off white, but turn darker in color as the buds mature. Depending on the strain, these hairs may turn yellow, red, brown or even purple in color. However, this isn’t a fool-proof method as strains like White Widow tend to retain their white hairs up until the time of harvest.

Another popular method in determining if the buds are ready to be harvested is known as the ‘trichrome method’. Trichromes are the little crystals that you will see starting to appear on your buds. You will know your buds are ready for harvesting if the trichromes appear cloudy or milky-white under a magnifying glass. If the trichromes appear darker in color, your buds are nearing the end of their harvest window.

Once your plants are ready to harvest, you will have a roughly two week period to do so. This allows for a little wiggle room if you are unsure your cannabis plants are ready or not. Harvesting early or later will produce slightly different feelings when the buds are consumed.


The next step after harvesting your buds is to trim them in preparation for curing. By trimming your buds, the THC concentration will be much higher per gram. In addition, your buds will have a cleaner and more aesthetically pleasing appearance.

There are two methods of trimming: wet and dry. This simply refers to whether you trim your buds before or after they have dried. There are benefits to both techniques, so it is up to you which style you prefer.

To trim your buds you can either use a hand trimmer or a commercial trimming machine. Make sure you have gloves on hand, to prevent your hands from being covered in resin as well as preventing damage to the buds from the oil on your skin. Also have a drying rack ready for when you’re ready to set your trimmed buds aside to cure.

Below are five great bud trimmers, suitable for a variety of levels of growers.

1. Trimpro Rotor Leaf Trimmer

Trimpro is one of the most trusted brands of bud trimmers in the cannabis industry. This bud trimmer was designed to be both gentle and efficient. It uses leather ‘fingers’ to move the cannabis over the non-stick grates where they are trimmed by razor sharp, tempered steel blades. One benefit of this product is that it’s built at an angle, so you are able to retrieve the trimmed buds while the machine is still running. The blade height is adjustable as well.

This trimmer is great for large harvests, making it a great choice if your operation is or will be large scale. It is a little more expensive than other models, so those who are on a tight budget may be better off with another trimmer.

All of Trimpro’s products come with a one year warranty.

2. The Magic Trimmer Electric Automatic Handheld Bud Trimmer

The Magic Trimmer is an cost effective, small, handheld device ideal for growers with smaller harvests or those who want more control over the trimming process. This product is a great alternative to larger machines. It is incredibly lightweight, weighing in at just two and a half pounds. It allows for precise and tidy trimming.

This trimmer is built to be compatible with all types of strains. Even though it is technically hand held, it is automatic so it will greatly speed up the trimming process when compared to manually trimming by hand. It is also a very affordable trimmer compared to some of the larger machines, so if you have a smaller crop to harvest this is the perfect product for you.

The Magic Trimmer comes with a one year warranty.

3. The Triminator Industrial Trimmer System

The Triminator is the ultimate bud trimmer if you have a large scale cannabis operation. The product is made in the United States and has been rigorously tested. One great aspect of this trimmer is that it is equipped with a self-cleaning system. The machine has an automatic misting system designed to keep the drum cleaned at all times. In fact, this machine has one of the largest drums in the world: The Monster Drum. This drum is manufactured by Flora Hydroponics, another reputable name in the cannabis industry.

Because there is no need to disassemble and clean the drum at any point, this trimmer is incredibly time efficient. It is also advertised as being 2.5x faster than any other trimmer on the market with the same drum. It is capable of trimming incredibly large harvests, ideal for growers with a substantial amount of cannabis plants. It is on the pricier side, but a great investment for any large scale grower.

The Triminator comes with a two year warranty.

4. Growtent Garden 19-inch Bud Trimmer

This is another great manual trimmer for those with a small scale cannabis operation. The bowl is 19 inches in diameter and similar to the iPower 16-inch model, is transparent to allow for easy viewing. The bowl is constructed of stainless steel, making this trimmer incredibly durable.

Another advantage of this product is that the cutting blades are adjustable, making it customizable to your cannabis needs. Also like the iPower model, this product harnesses the power of 30 pairs of scissors. This trimmer comes with one razor blade, one serrated blade, two wire blades and a pair of scissors.

This product is only suitable for small harvests, so if you think you may expand your operations anytime in the near future this trimmer may not fulfill your needs.

Growtent Garden also offers a 16-inch model as well.

5. The Triminator DRY Trimming Machine

The Triminator DRY, also designed by Flora Hydroponics, was created for growers seeking a trimmer that could work faster, cut closer and go longer between cleanings. It is also specifically designed for dry trimming, as the name suggests. This model features an automatic timer, which allows you to walk away and come back when the process is complete.

This product also comes with a removable trim bin. This is great for growers who are looking to save their trimmings to make edibles or hash. The bin is food grade as well. There are also retractable wheels, which make moving the machine simple but allows for greater stability while operating.

Keep in mind that while dry trimming has its advantages, it ultimately creates a completely different product than wet trimming.

The Triminator DRY has a two year warranty.


Drying is the first step in the curing process. If you wet-trimmed your buds then you will need to hang them for them to finish drying. If you dry-trimmed your buds, then you can move on to the next step immediately.

After the buds are mostly dried, you can move them into mason jars to finish the curing process. The purpose of curing buds before they are consumed, is to enhance the flavor and overall quality of the product. Typically you will cure your buds for two to four weeks.

During the first couple weeks, you may want to open the jar for a few seconds each day to release any excess moisture that may have built up. After two weeks, you can cut down to opening each jar once a week. By this point, any remaining moisture should be mostly gone.

While the buds will be theoretically finished curing after two to four weeks, many growers choose to cure them for longer. This is because the longer they are cured, the more potent the buds become. Some growers cure their buds upwards of three to six months.


There are several accessories that can help to make your life easier when growing your cannabis plants.

iPower Soil pH Meter, 3-in-1 Soil Test Kit for Moisture, Light & pH for Home and Garden, Lawn, Farm, Plants, Herbs & Gardening Tools, Indoor/Outdoor Plant Care Soil Tester

For example a pH meter will help you to constantly monitor the pH levels, making sure they are at optimum levels. When measuring the pH, measure in the “root zone” which is the area directly around the plant’s roots. Remember that if the pH is too low or too high, your plants will not be able to absorb the amount of nutrients they need and they may start to show signs of deficiency.

Another helpful accessory is a PPM or “parts per million” meter. This meter will measure the concentration of the minerals in the water you give to your plants. This is helpful because your plants can only absorb so many minerals at a time.

Grow glasses are an essential accessory if you want to avoid potential damage to your eyes. Even though you are growing indoors your LED lights will still emit potentially harmful UV rays. Buying LED specific grow glasses will ensure you are fully protected.

A 24-hour timer can be a helpful addition to your set up as well. By setting this timer up for your desired lighting schedules, you will have more freedom to go about your day without having to worry about your cannabis plants. Buy a timer that is able to be customized for all phases of plant growth.
