hello all. Check out my journal to see whats in the mix as of right now. I made this thread because i recently added a UV B light to my 2 plant micro grow but i was wonder if anyone has done tests as to how long to leave the thing on for. Right now it turns on for 5 hours in the middle of my 12 hour on schedule. Ive seen a few videos, ive read some threads but im just looking for feedback from people who have used a UV b themselves. Mine is 14w 5% uvb btw
