I have a Iguana and hes has grown through out the years leaving me with alot of light fixtures and his Repti-Glo 5.0 UVB Flouresent lights. I was Wondering Because i have TONS of these if i could use them for growing?
You can use them to supplement other lights, but probably won't get the job done by themselves. Like l3ored says, there is some evidence that it can increase resin production when used during flowering. Here's a thread with some good, more technical info: https://www.rollitup.org/advanced-marijuana-cultivation/96571-10-0-uvb-light.html
