Get your hard hat on! It is time for a marijuana grow room. Growing Marijuana Guide – Indoor Grow Room Basics
Building your grow room will probably the most physically exhaustive part of growing your own marijuana indoors. The room can be anything from a bedroom closet to a home-built grow box. There are a couple of things to take into consideration when choosing a grow space.
Temperature: The temperature of the grow room should not be excessively cold or hot. Marijuana likes temperatures between 70 and 85 degrees. Keep in mind that the lights will raise the temperature. If you want to grow in a space that cannot provide temperatures within this range, you will need to bring in heaters or air conditioners which can be hard for a first-time grow.
Humidity: The room should not be excessively damp or dry. Marijuana likes around 40-
60% humidity, so make sure you can maintain the humidity in this range. You may use a humidifier or a dehumidifier if necessary.
Light: The grow room should be isolated from external light sources. Light leaking out of the room can tip people off that something is going on and if you are trying to hide your garden from somebody, this is a dead giveaway.
More importantly, though, the plants need to have as minimal light as possible during their lights-off phases. Cardboard and duct tape are a great way to seal light leaks.
Size: The location you choose will need to be high enough to support an adult plant (depends on strain) and will need to have enough surface area to support however many plants you choose to grow.
Location: Location is very important. You don’t want the plants in high traffic areas where they might be spotted or people may interfere with their optimal growth. You also don’t want to plant somewhere next to electrical equipment or heating systems. If you need to get repairs done, the repairman might spot your crop.
Once you’ve found a suitable location to build your grow room, it’s time to start building. The first task is to work on your circulation. For small operations (1-3 cannabis plants) circulation can simply be opening the door to look at your plants every day, but having good circulation is important to maintain temperature and humidity.
Also, plants exude waste materials through their leaves and if this accumulates, it can be bad for the plants. A good source of circulation is a simple CPU fan connected to an AC adapter.
These can be connected relatively simply, but any fan would work. The fan should be used to take air in through some opening and should expel it at an exhaust hole on the other end of the room. Be careful not to let too much light leak through the exhaust system of your marijuana grow room!

Next, you’ll want to do is cover the walls with some reflective material. This can be as simple as painting the walls white, but for maximum reflectivity, I recommend using Mylar wall-covering. Mylar is available relatively inexpensively at any grow supply store.
This should be placed on the walls smoothly and as completely as possible. Duct tape works for adhering it to the walls.
Then you will want to have some kind of platform to hold your lights. This can simply be a board holding CFL’s in clamps, any number of fluorescent tubes, or an MH/HPS ballast. The platform should be of an adjustable height to accommodate the growing marijuana plants. I recommend using a chain connected to the ceiling so that it can simply be hoisted up as the plants grow. Make sure whatever you
I recommend using a chain connected to the ceiling so that it can simply be hoisted up as the plants grow. Make sure whatever you attach the lights to can hold the weight of the potentially heavy lights. Connect the lights to an automated timer that will control the light cycles.
You are now basically done. The final task is to ensure the area is sealed in terms of light. It might be beneficial to place some kind of plastic surface on the bottom to avoid water damage. The way you build your grow room is up to you, but this guide should help a little. Be creative and have fun, you’ll be spending a lot of time here. Now you can germinate your seeds, or learn how to avoid damaging pests in your marijuana grow.
This guide assumes you are only going to have one grow area. If you are planning on operating a larger grow operation in which you would like to be harvesting as often as possible, you may want to consider have two separate areas or two separate grow rooms altogether, one for the Vegetative Stage and the other for the Flowering Stage.
