Excellent advice i appriciate it cheers, i too am only growing for fun its kind of a addictive hobby that got out of hand! i was only thinking of having 4 plants under EACH light so from what youve said it should work a treat.
Also are you growing Hydro?? if so what supplement you using & where...
The Vipar B3x3 is far better value and more powerfull output than the budmaster, infact you can use it for flower or veg. ive stalked the uk for the best LED lights for quality and value! vipar B series works fantastic!
