Well I'm also a new grower. I have the usual questions and usual probs. Although my first harvest was not a huge yield, the potency was through the roof. I'm trying to figure out if 1 400 watt setup is going to do it for a 5"x3" area. (I may expand the grow space depending on what I hear.) I'm thinking of picking up a couple Sun system 250/400 all-in-ones. What do you guys think? I just finished my last grow and am anxious to start #2. Any input will help. Thanks guys and keep Oregon green!
