Hi, I'm trying to build a small grow box under my bed and the space I have allotted for it is: Length: 24 inches Height: 30 inches Width: 30 inches I would be growing one jack herer plant and one super lemon haze plant. It's my first grow/grow box and I'm planning on making a simple wooden box with supplies from home depot. I'm very open to suggestions/advice about any factor of the process. I can also make a bigger space, but that's the space I would have if I kept the box under my bed, I'm thinking of using air ducts on the sides to circulate air.
