So come on then Merlin it's time for some feedback on some of your numbers ,oz per plant,average quality(yes you have showed some lovely bud shots.....but.....I'm more interested in all in quality)eg,with your lights being VERY high it must effect the bud lower down(below the top 24inches)and finally.I can't seem to in any way justify these ballasts you r using the cost is just to MUCH(£600)the 315s do save on power)... but ....apart from that surely a 600 digi, personality I've been using the I Sun pro ballasts with built in timers(no need for autopilots or such things) for 4 years now with £25 sunmaster duel spec bulb(good for at LEAST a year) with a half decent adjustwing reflector for £160 all in would have been ALOT more cost effective......again please don't think I'm disrespecting you i just can't get my head around WHY someone would go to so much expence in such a big way(grow) when the same if not better could have been had for HALF the expense......
