So, I have a crazy idea for stealth grow box, I'll use a large subwoofer box, it should be 1 x 1 ft wide and 2 ft tall, is it good enough for 1 - 4 plants? And I want to use a power supplier from computer to provide power for fan and lighting, do you think it's possible?
I wouldn't do 4 plants in such a small area. They'll be good for the first few weeks, but unless you're doing lst it's gonna be hard having even more than one. You also have to think about ventilation and how you're going to water them. It's a good idea, but the smaller the room, the less space you have to work with, and if you've done this before you'll know how crowded things can get with even a single plant. Not a bad idea, though. You might just have to get surgical with the amenities, such as light setup, watering, ventilation, etc. Good luck, man.
