I am weaning myself from HPS. My last grow was 90% CMH lighting; and surprised me at the results.....:thumbsup:

My current grow is half CMH and half HPS. Very disappointing...so far..(6 weeks flowering, with exactly the same criterial)

The plants are rotated...so everybody gets an equal share. This is the last time I do that experiment...:wtf:

UVb an experiment Quick background: I have been using UVb supplemental lighting for many years now and have always thought it added to the finished product in a couple of ways. I had never promoted it's use on these boards because I felt it was dangerous and had real potential to harm people. That changed a few months back on the other UVb thread, and I came out of the closet in strong support of it's use. Well some here who's opinion I respect (like Weezard) held the opposite view and those discussions led me Rating: 5
