How to build a grow tent for weed

All you need is a hula-hoop and reflective blanket material called Mylar. It was initially developed by NASA and is extremely reflective, ideal when trying to make the most out of your lighting. Make sure the hula hoop is large enough to fit around your light. This is because you’ll hang the Mylar from it, surround the light, and make it more efficient.

A lot of good LED grow lights are designed to be hung from thin cables. Therefore, you’ll have to figure out a way to fasten the hula-hoop around the light. Then you need to attach the reflective blanket to the hoop. The guy in the video attached his sheet using duct tape. Something tells us you won’t need Frank Lloyd Wright-like engineering skills to figure something out.

Test Your Light Without a Grow Tent First

Are you looking for a nice little 420-weekend project? Or have you always wanted to make a marijuana grow tent for next to nothing? If the answer to either question is ‘yes,’ then this step-by-step guide is for you.

Here is how the light compares with and without the Mylar at the three distances:

How to Build the Cheap “$2” Grow Tent for Weed

Not long ago, we came across a YouTube video from HowToHydroponics. It documented how to make a marijuana grow tent for $2. Given the average price of a grow tent, it is hardly a surprise that the title caught our eye.

The best way to hang your grow light is using rope ratchets if you can; they are cheap and easy to set up. Rope ratchets make it incredibly simple to adjust your lights at any time without the chance of dropping the light on your plants. Sometimes it’s helpful to be able to quickly put lights up or down, whether you want better access to the back of the tent without the light beaming on your head, or even just to take better pictures of your plants. Make sure whatever you use to secure the lights (rope ratchets!) can handle at least twice te amount of your light just to be safe!

After everything is set up, turn on your grow light and exhaust fan for a day to test out your new space.

You can dramatically reduce the sound of fans by hanging them as opposed to letting them sit on something. Keeping fans clean will also make them as efficient as possible while preventing sounds from developing.

Grow tents also let you easily set up a perpetual harvest. This grower (Manzfoo) keeps young plants in the purple LED tent, and older plants in the yellow HPS tent. As soon as he harvests the big plants, he rotates in the young ones and starts a new batch. This lets him harvest every 2 months or so!

Some grow tents don’t look particularly suspicious. On the left is a homemade stealth grow cabinet and on the right is a 2’x4’x5′ grow tent that looks vaguely like a clothes wardrobe. They’re just about equally nondescript!

If you want to double your yield from a 2’x4′ but don’t want to have to set up a whole grow room, a 4’x4′ is the way to go! It’s big enough for monster yields (a pound or more!) but still small enough to be manageable by just one person.

Before getting started, make sure you’ve freed an afternoon to dedicate to this project. Take a minute to clean up the space you will be building your tent, as it’s easier to do it all in the beginning as opposed to while you’re working. Make sure to put together your tent at its final destination! You don’t want to build it only to realize it doesn’t fit through the doorway

How to build a grow tent for weed

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.

That’s where a grow tent comes into play. Technically, you don’t need a grow tent to start an indoor plot, but unless you have access to a commercial grow warehouse, odds are your basement, garage, or closet is not a perfect set up for cultivation. Indoor growing is all about creating a micro-environment for your plants. By constructing an enclosed space, you can maximize light coverage, keep out pests and debri, filter air, and moderate temperature and humidity.

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.

Why build a grow tent?

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.
