DutchPimp... I know you spoke highly of the 'White X' line from Attitude. Any idea as to how well they handle heat? I have a feeling temperature's going to be a factor during flowering in the generation after these.

I stay below 85 degrees. I measure that; in the space between the light and the canopy.
(offset, out of direct light rays)

I don't know what the max limit might be? Good light + good soil + good temps = good weed

Bottomline: if things get too hot?...raise the light until temps improve.
