I was asked to post these pics on another forum and I am pretty proud of them so I wanted to share them here.
This is over last year through the winter while I ran tests with the 600w
Hortilux Blue MH, the
Hortilux 600w Super HPS and the Phillips 315 cmh 3100k bulb.
I was planting a seed or cutting and harvesting a plant every week. Ran clones of favorites 3 times each.
Room is too hot for the third lamp in summer.
I like 2 hps and 1 cmh or maybe 1 of each best. And the 600 blue is showing the same benefits as cmh but at a bigger footprint and higher yield.
But I lost 30% yield with a 315 and got looser lower buds and too much leafy bud growth compared to a 600 HPS.
Guess it is all and always will be hype. :-)
I do think multiple 315's in the same space would kill.
