I want to turn my closet into a growroom, I was planning on doing a hydro grow. The closet is 2x7 x 7high
From your description it sounds like a standard closet with those bi-fold doors.
If this is the case, How are you planning on venting it?
If your thinking of a 12inch oscillating fan was all you were planning on using.
Then forget it....Your plants will suffocate and die.
Those small ass closets get hot...very hot.
You could setup a passive intake into another room then setup an exhaust blower, blowing outside a nearby window.
Plus, I hope you have an outlet inside there that's is on it's own circuit and has 20 amps at least.
Your going to be running some serious wattage, with all your lights, pumps, and fans. Forget about using extension cords, that's a good way to set fire to your house. It's happened to alot of people.
If it doesn't have an outlet inside the closet your gonna have a shit load of cords coming out of your closet.
Also, how do you plan on sealing off your closet. It's gonna seriously stink up the entire house, if you don't seal it off.
Just some things to think about, Believe me when I first got into growing, my bedroom closet was my first idea. But when I gave it alot of thought, I knew it would of been a huge pain the ass.
