Thank you
I've been growing with a 200w CFL for over a year with great results, but i was in my local grow store over the weekend and the owner had a used 400w lumatek electronic ballast, 400w bulb and the socket for $100 and figured why not. I've have a room with 2 x 600w at a different location and love the results. I do all my experiments and breading at home and now dont have to guess how they'll grow when i put them under HPS lights, theres a big difference from CFL vs HPS. though dont get me wrong if you know how to grow under CFL you'll be surprised what you can produce.
