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.
• A proper LED grow light – We use the 1000W LED Grow Light by BESTVA
• Clothing hangers or clips to attach the grow lights to the top of the closet.
• 3 Gallon Plant Grow Bags by VIVOSUN
• Soil – we use perlite soil
• Cannabis seeds – check out our guide on seed banks to buy some seeds online.
• Flower outlet timer to help track flowering and timing.
• Provided airflow via this CLOUDLINE T4 grow tent ventilation system along with TerraBloom 4″ tubing.
• If you have a small oscillating fan, I would recommend using it as well.
• VIVOSUN 4 Air Carbon Filter for the smell.
• Optional – OdorStop HEPA Air Purifier if you’re worried about the smell.
• AcuRite Temperature and Humidity Gauge.
• FoxFarm Big Bloom Nutrients

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!
