After doing some simple math, you’ve reached a value of 3000W and now you know that, for example, if your light fixture consumes 400W and your exhaust fan 150W, it comes down to a total of 550W and the max wattage for that circuit is 3000W so everything should run smoothly.

This is why a grow room must be 100% light-proof, it will not only allow you to maximize light usage but will also avoid any problems with your plants.

An air-tight grow room 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.

Helps control humidity

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.

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.

Proper ventilation also helps you maintain humidity levels on point because it is super important, especially during the flowering stage so by having a good ventilation system you can get rid of the excess moisture caused by the water the substrate retains and the moisture your plants release through transpiration.

Waterproof

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).

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.

Once your shelving, lights, and wiring is all good to go, pull out your panda film or mylar and start wrapping the rack to create your tent. Because the tent is made to keep all of your light inside, reflecting, and focused on your plant, make sure that there are no light leaks and that your chosen wrap creates a floor and a roof to completely encase the structure. Leave one side of your box open and create a door using more of your chosen tape and with a pair of velcro or magnetic adhesive strips. You’ll need to access the inside of the tent to water and feed your plant(s), adjust the light height, and eventually, harvest your buds, so making sure your door is both accessible and light-sealed is important.

The first step to assemble your grow tent is putting together your frame, or in our case, the wire shelving rack. Once you’ve put in a top shelf to hang your lights from and a bottom shelf to hold your plant(s), use zip ties or a wire hanging kit to string your light below your highest shelf. Zip tie and duct tape your wires and timer along the frame of the rack. Set up your fans to circulate the air and push any heat generated by the lights towards the top of your shelving.

Traditionally, the structural bones of a grow tent were made out of PVC pipe or wood. For the construction novice though, using a ready-made wire rack for your grow tent frame is by far the easiest option. The removable, adjustable shelving units will allow you to easily hang lights, fans, and hold your plants without building a micro-ballast or custom shelves. A standard 36” x 12” x 54” shelving unit is perfect for housing 1-2 plants, while a wider 36” x 24” x 54” rack could potentially fit 3-4 small pots.

What material do you need for a DIY grow tent?

Thanks to the legalization green rush, the cannabis grow industry is thriving. That means that there are plenty of relatively cheap pre-built grow tents available if you don’t have the time or energy to make one yourself. If you’re committed to a DIY grow tent, though, the first step to sorting out your material list is deciding on a frame and size.

The next step is setting up your ventilation system. To ensure proper ventilation, cut a hole in the top quadrant or roof of your tent and connect your ducting to the exhaust fan and make sure you can funnel the forced air either outside or into an attic or basement to keep the eventual odor down. If you’re really worried about the smell of your indoor grow, install a carbon filter in the middle of the exhaust set-up. If you want to get fancy, set up a thermometer, humidifier, and dehumidifier in your grow tent for peak environmental control.

Just because your apartment doesn’t have the same acreage as a farm in the Emerald Triangle doesn’t mean you can’t grow your own ganja. In fact, with just a few trips to your local hardware and garden supply store and some simple assembly, you can construct a DIY grow tent and produce your own weed year-round.

Why build a grow tent?

To recap, here’s a checklist of everything you’ll need for your DIY grow tent:

To keep the light focused and reflected as much as possible onto your plants, the next thing you need is the “tent” part of your grow tent. Using a material that is bright and reflective on the inside and black on the outside will properly direct the light onto your plants while ensuring that no light leaks out. This kind of rack wrap can be built on the cheap using reflective space blankets and layers of black trash bags. For just a little more money, we recommend investing in black and white panda film or one-sided mylar wrap.
