I would get a HPS converter bulb 400 watts, you will more than double youryield with the HPS.....Good luck!!!
budman2000 Reviewed by budman2000 on . Environment change during flowering I started flowering under 300W of 2700K CFLs 10 days ago. I unfortunately need to move my plant from its current growing situation and the only place it can go is under a friend's 400W MH bulb for the remainder of the flowering stage. What can I expect? =/ Rating: 5
