How To Build A Grow Room

The first step after deciding to grow weed is to set up the space to do it in. There are pretty much 2 options when it comes to setting up a grow room.

1. Buy a pre-made grow tent

2. Build your own grow room.

The first option is obviously pretty simple. Just order the size of the tent that you want, they come in a ton of different sizes now and are pretty affordable.

The next option (in our opinion the better option) is to build your own room. Building your own room can give you the following benefits:

More Space
Can prepare an entire room
Can be any size you wish.
So lets get started building your own grow room. The first step is to obviously pick a room that you can use for a long period of time. This may seem obvious, but making sure you are in a room that has an adequate power supply has caused many growers problems. Depending on how many lights you plan to run, you may actually have to do electrical work. If you are running two 1000watt bulbs in a room, on a standard 120v connection , you need to have at LEAST 16amps available on that circuit breaker. The equation works like this.

Watts / Volts = Amps used.

So with two 1000watt lights on a standard circuit for a house you would have:

(1000watt + 1000watt) / 120 volt = 16.6 amps

Now if your room has a 15 amp circuit, you are already screwed. You can do electrical work to run a new wire to the room, and use a larger circuit. Or you can use smaller wattage lights. If it comes down to it, you can run extension cords from another outlet on another circuit in your grow room for more power.

Hopefully you have found a room with adequate power. Now you need to think about ventilation. Does your room have window that you are going to use? Venting the heated air from your lights out of your grow room is important. If the temperature of your room gets too high, your plants will suffer. There are 2 options when deciding how to vent your room. You can either vent the heated air to outside of the house, or outside of the grow room to the interior of your house. Either way you go, I would recommend a Hydrofarm Active Air 6 inch In-Line Fan 400 CFM because they not only work great, but fit with most light fixtures, and charcoal air filters.

Both options have benefits and drawbacks. Venting the air out of the house gets rid of the heat. However, the air that is being pushed out of your house needs to be replaced. If you are running heat or a.c. that air is going to be exhausted out of your house, therefore air is going to leak into your house to make up for the space. This could raise your electric or gas bill by having to run your furnace/ a.c. more to keep your house at the temperature you want. Also the exhausted air needs to be cleaned to get rid of the smell before you dump it into your neighborhood. Charcoal filters do this, but for a good one, they are not cheap.

Venting the air back into the interior of your house will cause the temperature to rise slightly. If it is winter and your furnace is on anyway, this will not cause a problem. If you are running your a.c. it may raise your energy bill. The smell will also encompass your entire house unless you use a charcoal filter to scrub the air. . Ventilation will often depend on the room you are using, its shape and size, even the location of the room in the house. Typically growers have rooms available in their house and pick the one that is most suitable.

So after you have considered the ventilation and power supply for your grow room, you are ready to begin.

The first step is to clean the room as thoroughly as possible. Begin by vacuuming everywhere possible, even the walls. Next you want to clean every square inch with a disinfectant. Using a pressurized sprayer
will help you spray every square inch. Then wipe down all of the excess water and disinfectant to prevent mold or mildew from growing in pools of water. Let the room dry completely.

You are now ready to begin actually constructing your grow room.
If you are using a room with a window, the first step is to cover the window with a blind or shade that will look normal from the outside. Then you can cover it with drywall, cardboard, plywood, pretty much anything that will create an airtight seal and block the light from being seen from the outside. If you are using it to vent the air outside, you will want to cut a whole with the desired size for the air duct to vent out of. There is more on this in the video posted below.

If you are worried about police seeing the temperature difference in your house with a flir camera you may want to put up insulation or infra-red barrier to block the heat signature. If you are in a room that is on the exterior of the house, or in an attack, this is something you may want to consider. It is not absolutely necessary, in the U.S. it is not legal for the police to drive down the street with a flir camera looking for houses to raid. However, it is always best to err on the side of caution then to not take steps to ensure the safety of your grow room.

If you are using part of a room, you want to erect 2×4′s to partition the room into sections. I will leave this step up to you because every room is going to be different. I would recommend that if you are going to put up a wall to break the room up, space the 2×4′s out as if they were studs so that you have support for your Visqueen.

Keeping your plants off of the ground is very important. The ground tends to stay cool, so you are going to want to keep the plants elevated slightly to ensure the roots are kept at a suitable temperature. One way to do this is to put down sheets of Styrofoam on the ground to act as an insulator. Depending on the system that you want to use, there are endless options to keep the plants off of the ground.

Now it is time to cover your walls and ceiling with Visqueen. Using plastic sheeting with one white side to reflect the light, and black on the outside to prevent mold and fungus growth is the best way to ensure the viability of your plants. You want to cover all of the walls, ceiling, even the floor. I recommend using a staple gun to secure the plastic sheet to the walls. Be sure to pull the sheet tight before securing to the walls. You don’t want to have loose hanging plastic dangling from your walls or ceiling, it can lead to the growth of mold or fungus.

Hopefully now you have a room covered in Visqueen with adequate power supply and ventilation. In the next installment we will begin selecting and putting up lights for the grow room.
