How to Grow Weed In A Closet – No Smell, No Worry
Are you looking to grow your own marijuana but don’t have the space or the privacy for an outdoor grow? Well thankfully if you get a little crafty, and are willing to test a few methods, you’ll be able to grow weed inside your closet!
Growing weed in your closet isn’t as simply and methodical as a traditional outdoor grow, and it does involve you getting a bit inventive, but once you get the hang of it, it’s a viable solution!
You might be wondering, can you grow weed in a closet and if so, how do you grow weed in a closet?
Well in this guide below we’ll be running you through our exact process on how to grow marijuana in a closet without upsetting your neighbors or smelling up your house or apartment!
What Are The Difficulties With Growing in a Closet?:
One of the main difficulties involved with a closet grow is simply the lack of circulation. Cannabis grows require quite a bit of fresh air and air movement, and of course a closet isn’t the best at that. Along with this, cannabis plants of course require “sunlight” or at least an artificial light to help stimulate the natural flowering process of the plant, and obviously you don’t get this in a closet.
So how do you solve this?
Thankfully indoor grows are nothing new to cannabis, you just have to be a bit more picky when you’re dealing with close quarters. In our process below we’ll specify what you’ll need, what type of seeds are best, how long it takes, and everything else you’ll need to grow cannabis inside your closet.
How Big of A Closet Do I Need?:
Growing weed in a closet is designed to be a small space grow solution. But just how big of a closet do you actually need?
You can get flexible based on the size of the closet you’re working with, but you’ll definitely need enough space for your grow lights – the lights I used are around 12 inches long by 9 inches wide, and they’ll need to be hung up, so you’ll need space for these to hang.
Along with this, you’ll need to have space for your containers which hold your plants and enough vertical space for the plant to grow uninterrupted.
Usually my plants are around 36 inches – 48 inches high, so generally a normal sized closet will be suffice for this.
Of course the bigger the closet the more plants you’ll be able to grow, but if you have a small closet you should still be able to fit at least one plant.
That being said, when you are dealing with a tiny closet, you’ll need to be sure that you focus on ventilation because small spaces makes it difficult for the plants to get the proper air circulation they need. But this can be solved by a proper set up.
Equipment Needed For a Closet Grow:
Below is the following equipment that we use and we recommend for your cannabis closet set up:
A closet that is at least 36 inches wide by
24 inches deep. Most full sized closets are bigger than this, so you should be fine.
Okay, now that we’ve gotten through all the things you need, now it’s time to get into the exciting bit, and get to the step by step guide!
Step 1: Setting Up Grow Lights:
As mentioned earlier, you’ll have no grow if you don’t have any grow lights.
We personally use the 1000W’s by BESTVA. I really like these lights and they have higher Wattages if you have more space available.
You can technically use other types of lighting, but LED are much more stable, much more cost effective, doesn’t produce as much heat and much more energy efficient, so they’re always my go to. This specific grow light is also easy to install which makes it a breeze to set up.
Each light will have it’s own directions on how far away it has to be from the plants, so you’ll just have to keep this in mind as your attaching your grow lights to your closet. I personally attach them via wire to my wire clothes racks and then adjust the height accordingly.
Step Two: Setting Up Your Plants and Grow Medium:
When you’re growing weed in a small space such as a closet, you have to think about space and how big of containers your plants will be in. I personally use the 3 gallon grow bags from VIVOSUN for once the plants are past the nursery stage.
If you’re germinating the seeds yourself, then definitely use the paper towel method. Once the seeds are germinated, then I typically start them off in a red solo cup until the plants are a few inches high, then I transfer them into the 3 gallon grow bags with additional soil.
That being said, when you’re picking your strain, I would definitely recommend you choose a shorter height strain, just because you don’t have as much space as you would if you grew them outside. Generally speaking, autos-flower strains are usually under 36 inches in height, so they’re usually a good choice.
Step Three: Setting Up Ventilation and Carbon Filter:
One of the most important things about a closet grow is ensuring that you have proper ventilation, air flow and odor control. Cannabis plants need fresh air to grow and since closets are so tight you need a system to help bring in fresh air and keep the air circulating.
Along with this, if you’re growing in a closet you probably don’t want your neighbors finding out or your house smelling, so by using a carbon filter, you’ll really help to keep the odor down.
I personally like to use an oscillating fan along with CLOUDLINE T4 ventilation system and I’ve had no issues. The nice thing about this ventilation system is that it’s designed specifically for closets and grow tents.
During this time you should also set up your temperature and humidity gauge, I advise putting it in an easy to read position, so you can check it at a glance.
Step Four: Tending To Your Plants:
Now that you have your closet grow set up, you can start focusing on the actual growth of your plants, and get you one step closer to harvesting. I generally advise to check on your grow at least once in the morning and once at night to ensure that temperature and humidity is ideal, and all the fans and exhaust are working properly.

Step Five: Harvesting:
Just like an outdoor grow, harvesting your plant is the most exciting and rewarding part of the whole process. Harvesting a closet grow is just like an outdoor grow, and you’ll need to trim and cure the buds before being able to consume!
Final Thoughts on Growing Cannabis in your Closet:
Overall, your first closet grow can be a bit overwhelming. You do need a bit of equipment to get it all set up, but thankfully you can reuse all the equipment in future closet grows, and the investment is definitely worth the effort!
The actually process might seem complicated, but once you have your first grow under your belt, it actually gets much easier and allows you to experiment with different set ups and see what works best for your! Please leave a comment below if you have any specific questions with your closet grow!

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.
