start off with some smaller CFLs to get the plants started, then when they get big enough go ahead and get a 250w or 400w HPS lamp, just like shake said, those things get hot, so make sure to get some type of ventelation.
JMORGAN Reviewed by JMORGAN on . rookie at work Hello everyone! First timer with a space to use. It is 21in. deep by 76in. wide by 78in. high. I have read lots of stuff but am still confused, was thinking of using 400 watts and try the sea of green approach. What do you guys think? Any and all suggestions are appreciated. thanks! Rating: 5
