Will 80-85 be ok?
hi chester, depends where u measure from, i would be happy with that though. take the temp at soil level, the plant will be ok with higher temps near the light. I have mine as close as poss without touching.

the 15L pots will be ok, you should flush them when going into 12/12 and before changing to the higher P bloom ferts.

I'm doing a grow with 200w CFL at the mo. I lst'd a few plants and they are now on day 39 flower - there's a grow log wiv lots of pics from when they were little. http://boards.cannabis.com/showthread.php?t=88633
