I have only got one grow of these beuts under my belt at present. I tried 1 Russian rocket fuel under 250w cfl 6400 for entire grow in 150mm square pot. grownin coco, 1/4 nutes for 2 weeks & did not want more than half till harvest.Performed ok, looked awesome,bout 70 days fromsprout on 20-4 but yield was disapointing. Also grew 1 strain called assasin, veg in 250cfl for two weeks then chucked it in main room on 12-12. Also I cut the bottom of pot out, filled up another one & sat it on top so roots could grow down more. Fuck me it loves it! On 3/4 nutes same as my girls, I would say it will put anothercouple of weeks on because of 12-12 regime but hps is the way forward
if I had the choice I wouldleave her on 20-4 but hey! I wouldsay yield on this one going to be 1.5-2 dry compared to .5-.75 under cfl. So IMHO 4 pots under yourhps will give you quite a nice grow but deep pots are important I think,
like I say I have only just started on the auto route but hopefully this little bit of info helps,
cheers
