Growing Weed In A Closet – A Guide To More Yield With Less Effort
Closets have always been a close ally of the clandestine grower. People have grown weed in closets since the early days of indoor cultivation in the 1960s and 1970s, so we thought this topic is something we definitely needed to include in our series of articles dedicated to growing cannabis indoors. If you’re looking for a low-key area to house your small-scale grow, you can’t beat a closet. In this post, we’ll outline some benefits, pitfalls, and best practices related to growing weed in closets.
Benefits Of Growing Weed In A Closet
There are plenty of pros to growing weed in a closet. First, it’s one of the simplest ways to get a grow up and running. When you grow weed in your closet, you already have an enclosed space that’s perfect for keeping out light and controlling your environmental conditions with minimal effort.

Second, growing weed in a closet helps increase the overall stealth of your garden. A marijuana closet grow doesn’t draw the same amount of attention that growing weed in your yard or even a grow tent does. You can also manage the smell from your closet grow fairly easily.
Turning Your Closet Into A Cannabis Grow Tent
To convert your closet into a cannabis grow, you’ll need some equipment. Below, we’ll cover what gear you’ll need, and have also included a step-by-step guide detailing how to grow weed in a closet.
Before you start growing, you’ll need the following gear:
- Lights – LED lights are longtime favorites for indoor growers because they generate low heat, which is simply perfect for such a small space as a closet.
- Light timer – An analog or digital timer is the easiest way to control when your lights turn on and off. This is especially important if you decide to grow photoperiod strains. Get a timer and don’t risk re-vegging!
- White paint or Panda Paper – This is to cover the inside of your closet. A closet that’s white inside will be especially effective, as the surface will reflect much more light that can be used by the plant.
- Growing medium – Soil, coco coir, rock wool.
- Carbon filter – This is to control the smell and not let it out of the closet.
- Containers – Pots for your plants.
- Tray – For drainage.

Process: How To Turn Your Closet Into A Cannabis Grow
Once you have all the necessary gear, you’re ready to build your closet cannabis grow. There are three crucial components to this process. First, you’ll need to get your closet ready. Then, you’ll need to set up your lights. Finally, you need to install proper ventilation.
Step 1: Pick And Prepare The Right Closet
Before you can get started with your closet grow, you need to pick the right closet. You’ll want to choose one with as high a ceiling as possible. This will give your plants room to grow vertically, which is especially important for Sativa strains.

Next, you need to prepare your garden before you can put marijuana in your closet to grow. Your main goal here is to make your closet as close to a grow tent as possible. Therefore, you have some work to do. Paint the inside of your closet white (or line them with Panda Paper) to reflect all of the light inside it. You’ll also want to eliminate any light leaks that allow light to pass in from outside your garden.
Step 2: Pick And Set Up Grow Lights
Now that you have your closet weed grow set up and ready to go, you need to install your lights. Generally, LED lights are the best option for indoor growers. For one, they’re particularly energy efficient. As a result, LED lights are the best bang for your buck.
More importantly, LED lights give off significantly less heat than other commercial grow lamps like HPS and CMH bulbs. That makes it much easier to control environmental conditions using LED lights.
Cup Winning Cannabis Strains
Installing LED lights is simple – just place one LED light above every plant in your grow. Many LED lamps come with their own installation instructions, so make sure you read any documentation that came with your lights.
Step 3: Install Ventilation
It’s impossible to understate the importance of proper ventilation in a closet cannabis grow. Every grow needs good ventilation, but it’s especially true for closet grows. Since space is limited in these kinds of growing environments, you need to choose your tools wisely.
Ventilation has one main job: to get air out of your garden. All you really need to do that is a small fan and maybe some tubes for airflow. One super helpful tool for ensuring proper ventilation when closet growing is a carbon filter. Carbon filters help eliminate the odor that the plants in your grow will generate. As a result, they can be the difference between successfully nurturing your garden through harvest day or getting caught. If you do some drilling, you can also install an exhaust fan in your growing closet. If you want to get your grow closet ventilated with the least effort, simply open its doors and windows in the rooms once a day.
How To Grow Weed In A Closet
There are a few things to remember when you’re growing in a closet garden. First, space is at a premium. Therefore, you’ll need to make the most of every vertical inch or centimeter. Use training techniques to keep your plants from stretching upward too much. ScrOGging, SOGging, and low-stress training (LST) are all ways you can encourage your plants to grow wider, not taller.
Another tip for successful closet growing: check on your plant at least once every two days. If possible, check once a day – this may even become necessary as your plants mature. Checking on your garden regularly is the best way to avoid common problems like underwatering, infections, and nutrient deficiencies.
Strains Suitable For Growing In A Closet
One last thing you’ll need to consider when designing your marijuana closet grow setup: strains. Choosing the right strains will make the difference between success and failure. We outline some of the best strains to use below.
Choosing strains with low headroom will eliminate the headache from closet growing. Indica strains grow small and bushy, giving you plenty of vertical room to grow. In addition, autoflower strains can help new growers successfully navigate their first few grow cycles. Learn more by checking out our collection of compact strains, all ideal for indoor growing.
Aside from space, smell is the biggest problem facing your closet cannabis grow. Even if you grow your weed perfectly and design the perfect closet setup, smell can blow your cover. When that happens, all your hard work results in nothing.
Don’t let a nosy neighbor bust your closet grow because of its aroma. Low-odor strains can help indoor growers manage the smell of their gardens. We’ve compiled a collection of low-smell strains here that, when combined with a carbon filter, can significantly reduce the aromatic footprint of your garden.
The best way to determine what strains will work best for your closet garden is experimentation. However, there are some strains that are just naturally easier to grow than others. Luckily, we’ve already done the searching for you. Check out our list of easy-to-grow strains to help get your closet cannabis grow off on the right foot!
Perfect The Practice Of Growing Weed In A Closet
This is just a brief overview covering the basics of growing weed in a closet. You can use this knowledge to set up your own garden. However, the only way to perfect it will be through trial and error. Trust your instincts and the information in this post, and you’ll be harvesting your own closet weed in no time.

Everything I Used to Grow Two Cannabis Plants in My Closet
If you smoke a lot of weed, growing your own cannabis plants is a great way to save money on bud while learning essential skills for self-sufficient stoners. Last year, my husband and I decided to try growing two weed plants in the closet of our spare bedroom, partially as a learning experience but mostly to see if we could actually turn some old Northern Lights seeds into something smokeable. Spoiler alert: it worked!
This list includes everything we used to successfully grow two marijuana plants in the closet. If you have more space you can definitely do more than 2 plants, but as our first grow we wanted to keep things simple.
First things first: We used the Cannabis Grow Bible to walk us through the indoor growing process. Let’s just say “Bible” is an appropriate word for this book because it was a godsend and probably the main reason our plants yielded us any weed at all. This book walks you through every phase and digs deep into every detail of the process, so you know exactly what to prepare for as your plants grow and their needs change. If you read the whole thing you’ll have a botany degree when you finish, it’s that good. There are many variations of this book out there, as well as plenty of free blog posts and ebooks on how people grow their weed, so you might find one that works better for you than the grow bible, but I highly recommend having something like this on hand so you can learn as you go.
One reason we wanted to grow our own weed is because of the Northern Lights seeds we had from a friend. If you don’t already have seeds on hand, you can buy cannabis seeds online through Seedsman. They sell regular, feminized, and auto-flowering seeds from 80+ breeders around the world, so it’s likely they’ll have seeds available for your favorite strain.
We chose soil for our growing medium over hydroponics because it required less of an investment to set up. We used a Foxfarms soil and perlite blend.
The seeds started off in a seedling domed nursery in front of a sunny window to make sure they would sprout. From there, we transferred them into the solo cups for a little more space before moving them into 3-gallon fabric pots filled with the perlite soil, which were then placed in the large plastic storage bin. The plants stayed in the fabric pots for the remainder of the grow.
We insulated the bin using Mylar sheets and a spray adhesive to cover the interior sides.
We added some LED strip lights to the bin to keep light reaching under the leaves. These are the lights surrounding the small plants in the pictures. We ended up keeping them in there for the full length of the grow.
Once the plants outgrew the strip lights, we used this 600W LED grow light and an adjustable hanging system to hang the lamp from the closet rack.
We also made it very easy on ourselves with these mechanical outlet timers for when the plants started to flower. In this stage, your plants will require 12 hours of light and 12 hours of complete darkness, so if you use outlet timers to automate this process, you won’t have to worry about getting too high to remember to turn off the light.
Airflow / Odor Control
We regulated airflow with (4) 120mm computer fans and a 12 volt molex adapter, which can power up to 5 fans at a time. You can see where the fans were placed in holes cut into the side of the bin.
Once the plants get a little bigger, this 4″ inline centrifugal fan will keep the space breezy without too much noise. Attach it to this 4″ flexible dryer vent tubing.
This 4″x18″ carbon filter will keep your landlord’s nose out of your business. If that’s not enough, we also used this HEPA air purifier, which is worth every penny and a life-saver if you need to quickly get the smell under control.
We kept this temperature controller on the outside of the door so we could check the temperature at a glance.
This humidity and temperature gauge sat right inside the bin. It measures indoor temperatures and humidity every 10 seconds and has an alarm if anything goes off balance.
We also kept a small oscillating fan and ultrasonic humidifier going most of the time to help with airflow and humidity.
Water / Nutrients
This auto-drip irrigation pump and tubing system can be programmed to water your plants at whatever schedule you set, which is a must-have if you want to go away for the weekend.
The plants were fed using Fox Farm liquid nutrients and we just followed the directions on the bottle to determine what amount to feed them.
Make sure you have some nice pruning shears for trimming the leaves when the brush starts to get thick. Throw the leaves in a salad or smoothie for some tasty nutrition, or give them to your pets if they like leafy greens. My cats eat pot leaves like it’s catnip.
It took about 4 months for the plants to get to a point where we were ready to trim the buds and hang them to dry. We dried the stems on clothes hangers for about a week and a half before trimming the buds, then finally performed the ultimate test of smoking our first homegrown bowl of weed. We actually forgot to weigh the final product to see how much we grew, but we got high and we’re still smoking it months later so I’m going to call that a win.
For your home grow, remember that your first attempt is a big learning experience and that the amount of weed you’ll grow can vary significantly depending on your care methods, the seeds you choose, and the strain. Once you buy your setup and learn the process, you can expect to get more quantity and potency from your plants.
Growing weed indoors can be a fun and fruitful experience if you smoke a lot of herb. Here's everything I used to grow 2 cannabis plants in my closet.
