400w HPS 9 inches
too close...should be 13-17 inches...depending on the reflector. (not all reflectors are created equal)
Dutch Pimp Reviewed by Dutch Pimp on . Curling Day 18 flowering. 400W HPS on first pic with curling. 3 gal pots soil grow. T5's are not curling the HPS is. Any ideas? All nutrients are the same for HPS and T5's The only difference is the amount of fan, which could contribute to cold or the HPS. Any ideas? Rating: 5
