  1. Does anyone know if I can grow useing mercury vapor lights? Also whats the pros and cons on MH vs HPS lights?
  2. mv can be used but a hps is better in useage of powerx end yield.....go for a hps over the mv.....Peace out.....Sid
  3. I have used Mercury Vapor and it will work as Sidious said. One major disadvantage I found with the MV is that it produces alot more heat than the other types. Dried a few tops out before I clued in.
