Good luck!:jointsmile:

That's the thing: I have CFL's coming out the yin-yang from previous grows, I wanted (as an experiment) to do 12/12 from seed using the same lights...I have read about growers using HPS throughout rather than switching from Fluo or MH during vegetative to HPS for flowering...

Not having a proper light fixture for my 125 watt CFL doesn't help matters either. But...given the shaky start this grow is having, perhaps switching to CFL until sexing would be the right thing to do? :wtf:
