hey thanks for stopping by man! right now I have 6 x 23w cfls in an 18"x15" space. So thats 138w in 1.875 sq ft of space. It's hard to say what an average weight is because I have harvested some that got bad treatment and were less than a gram but I harvested one that was 2 grams and the Resin Hessassin clones I'm harvesting this week look like they will be over an eigth so it's hard to say, but I think my average will be going up very soon. Also I going to be incorporating 2x 55w Plls and expanding my chamber and possibly putting in a few more supplemental cfls.
