From reading through the forums, it seems like many people chose to supplement their MHs with VHO lighting instead of PC. Especially when building a canopy. I was wondering if there is a reason for this?
For me, it's because VHO actinics look signficantly different/better then PC actinics (even the "true" actinics). You'd like that given the same phosphurs used, they'd look identical. But that isn't the case in my experience.
