DIY Grow Room: Build Your Cannabis Indoor Grow
If you live in a place where cannabis is illegal and you want to grow your own, the best option is to grow your plants indoors. A grow tent allows you to control the temperature, humidity, and most importantly, prevent light leaks and eliminate the smell. Despite what everyone thinks, you can build a cheap grow box if you know which materials to use and how to build it, here are a couple of homemade grow tent ideas to help you save money and start growing in no time.
1. Main requirements
Before starting to build your grow tent, you need to have a couple of things in mind.
Even though you can grow cannabis anywhere you want, what differentiates a grow tent from any other growing space is its ability to keep light from leaking, being airtight so the exhaust fans can work properly and you can keep a stable temperature and humidity.
You can build good stealth grow tent as big as you want, with everything you need to, from the appropriate structure for the light fixtures to the exhaust fan and filter, and as long as you can accomplish the main requirements, you will have a fully functioning grow tent.
A DIY grow tent doesn’t stay behind a grow tent you would buy at a grow shop if you use good materials and take your time to do it and despite seeming like hard things to do, it is fairly easy.
The grow tent needs to be 100% light-proof, this is to avoid the waste of precious light and avoids your plants from stressing out.
When flowering, you need to provide a 12/12 light cycle, if there is a source of light near your grow tent when the lights are turned off, that light might get in and stress your plants, making them revegetate or becoming a hermaphrodite.
This is why a grow tent must be 100% light-proof, it will not only allow you to maximize light usage but will also avoid any problems with your plants.
If you’re planning to build your grow tent with plywood for example, you have to cover the inside with a waterproof material like a plastic sheet (or something similar).
By doing this you keep the wood dry and avoid rotting (keeping mold away from your grow tent). It will also make it easier to clean and you won’t have to worry about water leaking to your floor.
Air-tight (temperature, humidity, and airflow)
As you may know, growing indoors allows us to control and adjust the temperature, humidity and intensity of the airflow, because of this, your grow tent must be air-tight.
If you fail to keep air inside, your exhaust fan won’t work properly, it won’t keep the cannabis smell contained and it will be easier to get bugs.
An air-tight grow tent is a must when growing in places where cannabis is illegal, failing to contain smell (and light) in the tent can easily cause neighbors to report you to the police, so make sure you check this a couple of times throughout your growing cycles, as this can easily be fixed and will save your from a lot of headache.
2. Different types of builds
When building your grow tent, you can make it as big as you want to and out of anything you have available as long as you make it light-proof, air-tight and waterproof.
The easiest ways of making it are with a metal (wood or plastic) structure and a plastic sheet covering it, or building a closet-like structure with plywood.
3. Building your own indoor grow step-by-step
To start building your own indoor growing space you’ll need some basic materials and tools, some you might already have at home.
A grow tent is the best DIY grow space because (depending on how you build it) you can easily disassemble it when you need to and then mount it again without needing anything else.
To build a grow tent, you will need wood, metal or plastic poles, and a plastic sheet.
The size of the poles obviously depends on the height and size of the grow tent you want to build, but here’s an example to build a 1x1x2 grow tent.
First, you’ll need to cut and assemble the poles into something like this:
As you see in the image above, you’ll need 8 poles with 1m each for the top and bottom part of the structure, 1m x 3 poles for (E) and (F) and 2m x 8 poles for (C) and (B). If you want to make it easier to handle and assemble, you can cut the 2m poles into 1m x 8 poles and connect them with PVC fittings.
You will also need 8 PVC 3 way knees to connect (A) to (B) and (A) to (C), and 6 PVC Tees to connect poles (E) and (F) to (A).
If you’re planning on using a heavy light fixture (or more than one) and an exhaust fan with a carbon filter, it’s better to use metal poles so the structure can bear the weight.
After you have all the poles and connectors ready, you need to cut the plastic sheet.
The plastic sheet should be measured on the grow tent before cutting so you don’t have to redo it, make sure it doesn’t have holes to avoid light leaks and if it doesn’t get too hot where you live you can use 2 layers of the sheet to make the tent more resistant.
Even though the plastic sheet is waterproof, you will need to coat the inside of the grow tent with a material that reflects light like a mylar sheet or a white plastic sheet.
Note: Instead of using mylar, you can use a white plastic sheet, it won’t reflect light as good as mylar but it works great if you can’t find mylar easily.
A grow box is easier to build, although you cannot disassemble it effectively and the plywood can rot after a while because of the humidity and eventual water spills. To make a grow box out of plywood and wood beams, you’ll need a structure similar to the structure of a grow tent.
You need 1m x 8 wood beams for (A), 2m x 8 wooden beams for (B), and 1m x 2 or x 3 beams for (C). The amount of beams you need on top depends on the weight of your light fixture, exhaust fan, and carbon filter.
After you have the structure mounted, you need to cut the plywood to start closing the sides of your grow box.
You’ll need 1x1m x 1 and 1x2m x 4 plywood sheets, remember they need to fit perfectly so there are no light leaks and the grow box is as air-tight as it can be.
One of the 1x2m plywood sheets will need to be cut in half (for the door). You’ll also need 4 door hinges so you can open and close your grow box properly.
Tip : Even though it is not obligatory, you can glue pieces of rubber sheet where the plywood sheets meet and in between the door to make you maintain the temperature and humidity levels.
Because wood can get wet and rot, it’s a good idea to cover the inside with 2 layers of material.
The result of your DIY grow tent or grow box should be something similar to this:
With some minor differences, obviously.
After you have everything set up there are a couple more things you need to have your growing space up and running, these things are:
- Ventilation system
- Carbon filter
- Light fixture
Unfortunately, you cannot make them at home (unless you have experience with electronics), so you’ll have to buy them.
5. Exhaust fan
The exhaust fan usually goes on the top part of the grow space and is connected by a tube to the carbon filter.
The exhaust fans ensure a good air exchange, this is crucial to the growth of your plants because the air exchange will provide the CO2 your plants need while letting out oxygen.
A good ventilation system along a decent-sized fan will also help your plant’s stem develop tougher, helping them support the heavy buds in the flowering stage.
6. Carbon filter
The carbon filter goes directly connected to the exhaust fan (sometimes it’s connected by duct tubing) and it’s what will eliminate the strong cannabis smell before letting the air out, a carbon filter is crucial if you are growing indoors in a place where cannabis cultivation is illegal, this will avoid problems with your neighbors and the police.
Have in mind that when making your own grow tent or box you will have to make the holes where the duct tubing goes in and out.
7. Light fixture
As you may know, light is vital for growing any kind of plants, including cannabis.
Depending on the kind of light fixture you’re planning to use, you’ll need to make some adjustments so you can adjust the height of your light.
Some lights are heavier than others or maybe you’ll need to use more than one light fixture. So remember to test the structure you’ve made with the exhaust fan, carbon filter, and light fixtures (and maybe add more support) so you don’t risk killing your plants if the equipment falls on them.
8. In conclusion
If you want to start growing your own cannabis you don’t need to spend a lot, despite the cost of a ventilation system and lights, you can easily build your own indoor growing space by yourself.
Make sure you’re taking the appropriate measure so it’s solid, steady, and can support the growing equipment and you’ll have a fully functional grow tent while spending way less than buying one at a grow shop.
If you live in a place where cannabis is illegal and you want to grow your own, the best option is to grow your plants indoors. A grow tent allows you to contro

Tips For Gardening In Grow Tents

I know that it may sound tedious and it’s true that doing this will require some effort, but it will be worth it.
Using a grow tent alone just gives you the control to let your plants thrive well but making your own grow tent can let you have the upper hand when it comes to making sure that you have adequate space for it.
You can create a grow tent based on the available space you have wherever it is in your house or even the basement or garage.
You also get to choose the materials you use that depends on your budget or your preferences.

Key Requirements That Your Grow Tent Should Have
A grow tent should have functionalities that could help you grow your plants or crops. There are a few key requirements that should be considered to make a great grow tent. Here are some of them.
Shining A Light On Reflective Materials
Sure, you’ll get the lighting needs of your plants from any grow lights. However, your grow tent should be able to reflect lights efficiently.
You’ll find that commercially made grow tents usually consist of walls made with reflective mylar so it can efficiently bounce back light to your plants.
Your grow tent should also be a hundred percent lightproof. You need to be able to control how much light you have in your grow space, so you wouldn’t want light from the outside to obstruct your lighting set-up.
It’s best to have a grow tent that you can seal shut. An airtight grow tent allows you to have better control of your grow space’s atmosphere. It can also help you contain the smell of your plants.
Making your grow tent airtight can also help you avoid infestations that can be harmful to your plants.
Mylar and solid materials can help you create an airtight tent. You should always check for holes where air and light can escape from your grow tent.
Right Grow Tent Size
Of course, you can always pick the size of the tent that you’ll need, but a great tent will maximize the available space that it can give you.
Some commercial grow tents have compartments or pockets where you can store your tools.
Making your own grow tent makes you maximize the size of what you have.
You can check where you can install pockets or compartments for not only your tools but also other grow tent essentials like dehumidifiers and vent system that can consume some of your space.

I find this guide very simple and easy to follow. You’ll only need a few materials for this, with panda film as the main star.
Just like the first guide, you’ll also only need a stainless steel adjustable rack for this. It means that you don’t need to use heavy tools for this.

What you really need to do is to hang the mylar sheet around the hoop and have the light placed in the middle of your hoop.
It basically looks like a mobile that you can hang wherever you choose. Surprisingly, this can actually improve your lighting system.

This is one of those DIY grow box projects that could only cost you less than $100. In fact, the one who made this guide only had to spend around $50 for this.

The owner of this guide used ani industrial shelving unit for this project.
However, if you don’t have one, you can make use of any rack or shelves that you have. Just make sure that you’ll have enough space for your lighting setup. Alternatively you can use cob led grow light which is are relatively compact in size.
What stands out in this guide is the use of aluminum foil as the main cover or walls of the grow space.

This is another DIY grow tent project that makes use of a reflective sheet. For this, a window shield was used to reflect the lights back to the plant. It kind of has the same idea of how the $2 DIY grow tent was assembled.
You just really need to hang the window shields around plants you placed in this setup. Depending on how many reflective sheets you have is the size of this grow tent.
The main challenge here is how you can keep the window shield fall straight, but it works great.
However, just like the hula hoop set up, you won’t be able to seal the grow tent in this tutorial. It means that it’s best to have this placed in a room where you can control the temperature.
I find this guide very creative. All the materials you need are listed, and you’ll only need a few tools. Your budget for this setup will be less than $100.
What you can do to improve your lighting if you follow this setup is to purchase mylar sheets that you can put up inside the tent.
