hello everyone I've been thinking about making the switch to double ended hps. however I've heard from a few ppl that there is a 2-3% drop in THC as in going from 25% to 23% . is there any truth on this when these lights are properly used? I'm well aware of the many benefits of DE HPS but would like to hear any problems you might be having with these setups before I carry on.
