This guide is about growing hydroponic marijuana inside, so that the growing will be done inside. Where to grow your marijuana is dependent upon what space you have available.
An loft, closet or similar space will do, but a room devoted to growing is preferred. The largest problem most new growers face is maintaing the right temperature for the plants. A room with an exhaust fan on the ceiling is a good selection, if it is available. The exhaust fan on the ceiling will help in keeping the temperature cool, and if necessary, you can upgrade to a more robust fan to get rid of a bigger volume of hot air ( made by the grow-lights ). A piece of a cellar also makes a good area to line up a grow room.
An loft will work but heat could be a real problem unless very well ventilated. All grow rooms need unpolluted air ( from another room or outside ) to replace CO2 the plants breathe when the grow light ( s ) are on. About any grow room will require some kind of exhaust fan which will move hot air out of the grow room.
After you have decided where you are going to grow, you have got to clean the area and keep it clean. That suggests cleaning walls, cleaning apparatus, washing floors, for example. Carpets should be removed, if feasible. Everything in the growing area should be cleaned then sterilised with something similar to lysol, bleach, or some other germ killer to stop the marijuana plants from being mistreated by germs, bacteria, molds, and so on. If you’re going to grow in an area where the floor may be ruined by water spills ( there’ll be some ), the area where the hydroponic system is placed should have some type of floor covering which will protect it. A thick drop fabric ( the plastic sheets painters use to guard items from paint damage ) will do a good job.
Once clean, you can paint the walls and ceiling with white paint to reflect light or use black / white visqueen plastic. Commercial reflectors like mylar are often used for this reason because they’re better. Don’t use mirrors because they absorb light.
