As for the next step-by-step procedure, I’ll be explaining how to you can build a grow tent using cheap and affordable materials.

What You’ll Need

Step-By-Step Procedure

1.) You need to choose the size of your grow tent, which somewhat depends on the size of the available PVC pipes. This can be either 4 by 4 by 6 ft. or anything larger than that, as long as the PVC pipes are enough to offer the size you want.

2.) You need to physically draw out your tent on a piece of paper. This helps you have a better picture of what to expect. Most importantly, it aids in counting the number of PVC pipes you’ll need, and thus determine how you’ll fix them up.

Basically, you’ll need 16 pipes (4 for the vertical corners, 4 for the horizontal floor, 4 for the horizontal roof, and 4 others for additional support on the roof).

3.) You can now start by connecting the PVC pipes together using the PVC connectors. Start with the floor, then the corners and finally the roof and its support pipes.

Once the pipes are connected, check for stability. Make sure the frame you’ve connected doesn’t wobble or move easily when pushed. The last thing you want is a weak grow tent, because you’ll be installing lighting systems and other components like filters and fans.

4.) It is time to cover the frame with a reflective Mylar material. Take your scissor and cut the right sizes to fit the frames, starting with the sides before going to the floor and finally the roof. Make sure there is no light leaking into the tent.

Use the duct tape to attach the Mylar onto the PVC pipe frames. Once done, go inside the grow tent and check again for any light leaking into the tent.

5.) You need to leave an opening at the front as the door where you’ll be entering into the tent. Use the Velcro to separate the opening. Cut the front opening into half and use one side to attach the Velcro.

6.) You also need to make openings at the bottom and at the top where you’ll place the fans forventilation purposes.

7.) Install an LED lighting system. A recommendable affordable option is the ShengsiteLED lights, which is pocket friendly. Make sure you have the highest yielding led grow light.

8.) You’ll need to install inline fans and install a carbon filter, most of which usually come in pairs. You can check out a few Carbon filters for your grow tent. You also need to have planting pots for indoor gardening.

Important Considerations Before Building a Grow Tent

Now that you have all what you need to make a DIY grow tent, it’s advisable to accustom yourself with factors affecting the effectiveness of a grow tent. This way, whenever you are making changes to the tent, you’ll know exactly what to do.


Always make sure the grow tent never leaks in any light. The intention of having a grow tent is to control the light absorbed by the plants. And if there is any leak, it interferes with the light intake and thus affecting your plant’s yield.

For lightproof, the reflective Mylar films are there to guarantee maximum light absorption by the plants. This improves photosynthesis, which then enables better and healthier plant growth.

Also, with the right LED lights for grow tent, you’ll be maximizing your yields.

Waterproof and Controlled Humidity

You don’t want a grow tent that is not waterproof. Remember, grow tents are used for indoor hydroponic gardening. Therefore, when building your grow tent, make sure it doesn’t have any openings where it can leak water.

You also need the tent to maintain required humidity for the plants. You don’t want a tent that’s too humid or less humid. It has to be perfect and appropriate for the plants.

For waterproof, the Mylar works perfectly. But you can also add a protective second layer over the Mylar but on the outside. This is to make sure your grow tent is never flooded with water. For controlling humidity, you can consider a humidifier for grow tent, and if there are too humidity, just use a dehumidifier in your grow tent.


This is where the fan and the carbon filters come in. A grow tent needs to have a well-balanced airflow into and out the grow tent.

You can achieve this with an appropriate inline fan, which should be attached to the top of the tent. Hence, when building your DIY homemade tent, make sure you create an opening at both the top and bottom of the tent. This allows for airflow within the grow tent.

Size and No. Of Plants

You’ll finally need to consider the number of plants you need to fit into the grow tent. This is usually calculated by determining the size of the grow tent. If it is a 4 by 4 tent, then about 4 to 5 mature plants will fit in the tent.

It is advisable to make space and leave some room for the plants to breath comfortably without competing for air. Do not overcrowd the grow tent.

Final Thoughts

 If you are looking for a cheap way of building a grow tent, making your own homemade DIY tent is the best option.

Although the pre-made grow tents are becoming cheaper and more affordable, some folks cannot cough up 100 bucks to get one. Rather, it’s a better option to come up with something of your own, that you’ve built using what’s available around the house.

You can actually build a grow tent from a cardboard or a used tarp from an old picnic tent. The ideas are unlimited. You just need to make sure the tent is waterproof, lightproof and has the best ventilation.
