how to grow cannabis in your house

You Can Grow Cannabis In Your House!

Depending on what U.S State you live in of course. Find out of it's legal in your State here

Growing your own cannabis can be really fun. It can also be intimidating. There is a ton of information out there on how to grow cannabis, and it can be completely overwhelming. Home Growing Girl will give you the basics. My first grow was a comedy of errors (and some tears) but I ended up with a solid harvest and my friends were impressed and very happy with the quality, organic weed I grew. You can do this too!

All you really need is a basic understanding of how plants grow, the amount of light your plants need at each stage and how to create the right air flow and temperature. If you have had any experience growing house plants, annuals or vegetables, you can easily grow cannabis. If you don't, you can learn.

The Basics - Growth Stages for Cannabis

Germination - Germination is the process of getting your cannabis seed to "pop" or develop a tiny root that you can then plant.

Seedling - Your seed has developed a tap root. This means you are ready to plant the now seedling in your growing medium, either soil or hydroponic (water).

Vegetative Stage - You have planted your seedling and now your baby plant is developing roots and leaves. This is where your plant really starts to grow.

Flower Stage - Flowering (think buds) happens when your plant receives less than 12 hours of light a day, think end of summer. It is in this stage that resinous buds develop and is the final stage of growth for your cannabis plant.

What You Need to Grow Inside Your Home

What a Home Growing Cannabis setup looks like

A Grow Tent

Basically a tent gives you the ability to have complete control over your plants environment. Different stages of plant growth have different lighting requirements and you won't be able to have the necessary level of control if your plants are in a window or closet. A good quality grow tent gives you that control. They are made out of flexible materials (it's a tent) have a reflective inside to maximize your lighting and has structure and openings for your light, fan and carbon air filters. 

A Grow Light

There is so much to know about lighting. You could really geek out on lighting. Seriously, if you have an engineering type mind, you will love lighting. As a non- engineer, I finding lighting completely overwhelming and confusing. Do a quick search on cannabis grow lights and you will see what I mean. 

Here are the basics as I see them. Your choice of a grow light depends on how much money you have to spend, the size of your tent and your level of growing experience. More on grow lighting can be found here.

An Exhaust Fan 

You need an exhaust fan to expel stale air from inside your grow tent and keep the air moving. A good exhaust fan will makes sure that the airflow in the tent is recycled at a rate that is ideal for the plants, along with temperature and humidity levels.

Carbon Filter for Odor Control

An important fact to know is that as your cannabis plants grows, they will give off that strong, "I'm growing weed in my basement" odor. You will want to connect a charcoal filter to you exhaust fan, which will control the smell. The carbon filter is connected to the exhaust fan and blows the air directly outside and away from the fresh-air intake. Make sure that your filter and fan are compatible. 

Ducting/Acoustic Ducting

This silver flexible tubing is what moves the air from the intake fan and the exhaust fan. Think about your clothes dryer exhaust. Same idea.

A cheap alternative is standard ducting; however, if you spend a bit more, you can invest in a noise-proof version. This is well worth the investment and will distribute the airflow as quietly as possible. When setting up ducting, make sure that there is no sagging to make it efficient as possible.

Oscillating Fans

Once you have an exhaust fan and an intake fan set up and working, you’ll next want to add some additional airflow at the bottoms and tops of your plants. Oscillating fans will create a gentle breeze that will keep C02-rich air flowing around the leaves.

Chains and Hooks

When it comes to suspending heavy fans, large-size carbon filters and heavy LED grow lights, chains and metal hooks are the easiest and most reliable method.


A timer is required to control all of the electrical devices inside the tent, according to your light regime of either a 18/6- or 12/12-hour day/night light cycle. Carbon filters and fans should be left on permanently. 

Plug Extensions Cords

You can never have too many plug sockets available when growing indoors. To avoid a mess of wires, I personally like to have everything connected to one plug extension, which is left on permanently. I have a second separate plug extension for the grow light and timer. Some timers are bulky and can take up a lot of the space, so having extra plugs is always a good idea.

Plastic or Felt Pots

Traditional plastic pots are cheap and easy to find at your local garden or hardware store.

Felt pots cost a little bit more but have their advantages—they keep roots warmer and make pruning them easier.

Selecting a Growing Medium

If this is your first grow, then selecting an organic growing medium is probably the easiest solution. There are many “soils” available, but most are actually soilless mixes based on peat or coco coir. If you are just starting out, avoid hydroponic  (water as the medium) growing as it requires you to be SUPER hands and a water chemist. Soil is MUCH easier and forgiving.


Food for your plant. There are many nutrient brands available with a wide range of food covering all parts of a plant’s life cycle. One really cool company I found that sells organic plant food is Roots Organics. Though they appear to be mostly for commercial growers, they sell something called the Player Pack which includes an assortment of organic plant nutrients in one simple and relatively affordable package. They also provide a grow chart, so you can follow the weekly step-by-step guide.

Temperature and Humidity Monitor

These small displays can fit anywhere and tell you the temperature and humidity inside your tent. I have a basic one that has a magnet on the back, which I attached to the metal pole structure of my tent.  


During the vegetative stage, humidity should be close to 60 percent and decreased as the flowering stage commences. A humidifier generates a fine mist and can be placed either directly in the tent or in the room from where the tent is pulling air.

A dehumidifier will remove the moisture content out of the air. This is important during the flowering stage. If you’re pulling fresh air from outside where the humidity is very high, it can cause an imbalance and lead to serious problems. Luckily for me, I already had one in my basement.

Spray Bottles

Leaf feeding with water or a mild nutrient solution can be great for your plant’s overall health and vigor. You may want to use them for different nutrients or just water. so it’s a good idea to purchase a couple of different spray bottles from your local hardware, gardening store or Amazon. 

White Sticky Labels

This way you can label what seeds you planted if you plant more than one type of cannabis. It can be really easy to forget what you planted, so I avoid any confusion by labeling my pots early on.

And that's pretty much it. It can sound a bit overwhelming but it's really doable. It's always good to learn a new skill!
