How to Grow Weed in A Closet

The marijuana plant is known for being widely consumed and grown, but it can be quite a challenge to coax this plant into its full bloom. This is especially true when it is being grown at home. Yes, you can grow weed at home, but there are several factors that influence its growth. Some of these factors include lighting, air flow, temperature, growth techniques, nutrients and more. For beginners, this could be quite an intimidation. If you want to grow weed in your closet and you are not certain how to do this, read on. Let’s get started.

The Setup

The first thing you do is to choose your setup. You have a few options, but mainly the closed loop system or high CFM system, which means that you must select the best lighting option, and the right space. You also have to be aware of how hydroponic systems work and the nature of the soil that you will use. Other things to consider are surfaces easy to clean, proper water supply, reflective walls and sufficient lighting. You also need the ideal space to organize your tools and room for ample growth and consistent air flow. Choose the appropriate device so you can monitor the humidity and temperature.

The Germination Phase

For thriving germination, get all the materials needed to transform your cannabis seeds into marijuana sprouts. Of course, a medium will be needed for the marijuana seeds. You will also need a water basin, humidity dome, pH testing kit, seedling tray, TDS pen and a heat mat for your seedlings. Assemble all these materials and get started. You will also need to know how to change the pH in the water supply for added stability. Inspect the marijuana seeds and get rid of the worse ones before you start planting. Be sure that the environment encourages the growth of your seedlings. This is an important phase in how to grow weed in a closed environment. Give it a few days before checking back to see how your cannabis seeds are doing.

The Transplanting Phase

Now that your cannabis seeds are successfully germinated, it is time to do your transplanting. When you grow weed in a closet in your home, it will need to be transplanted after germination. It is pretty much taking your marijuana plants from its toddler stage to a teenager stage. When you germinate and transplant your seeds, it saves on water, supplies and nutrients. Find the right space to accommodate your fully grown plants.

The Nutrients

Nutrients are essential to successful growth of marijuana plants. If you grow weed in your home, you still need to use the right nutrients. If you want your plants to grow and survive successfully, you should use mineral and non-mineral nutrients like phosphorous, carbon, calcium, potassium, hydrogen, copper, chloride, oxygen, zinc, born and sulfur. There are different nutrient requirements for a hydroponic system and the soil based system. You also have to pay attention to your plants so they don’t suffer from nutrient deficiency.

The Vegetative Stage

You also need to know the various stages of how to grow weed and one of this is the vegetative stage. This is one of the most important stages in the growing process. During this stage, you have to make the right decisions for your marijuana plant. For example, the length of your vegetative stage will be determined by getting the setup done right in the beginning. During the vegetative stage, you have to ensure wise pruning, regular watering schedule, sufficient lighting, enough nitrogen and potassium and good airflow.

Final Thoughts

Other areas of importance include cloning your marijuana plants, if you want to abandon the germination phase. When the vegetative stage has been completed, then you will be armed with the right steps to deal with the flowering stage so you can be ready for harvest.

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.

Growing Medium

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.

Temperature 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.
