Well 400 watt models are historically the most energy efficient model (and differences can be dramatic) I think 400W is good size even for two very healthy plants.

Shovelhandle Reviewed by Shovelhandle on . Home depot lighting I am going to grow 2-4 plants inside a cabinet I am building. I'm going to make the cabinet about 30 inches deep or so and 5 1/2 feet tall and 4 feet wide. I was at Home Depot and saw some 240watt and 450watt lights. They were about 35$ a piece. I think they were MH or something like that. Is one of those enough? Do you think I could add a couple more types of lights that I could buy from Home Depot? Fluorescent maybe? Ideas? Second question...Can anyone recommend a good high potency plant Rating: 5
