I always keep them under the fluorescents for a few days before putting them under the hps.
Rubberbubbler Reviewed by Rubberbubbler on . Transplant and Change of light I am currently growing under 2 florescent T12 40w tubes from seed for 2 weeks and am going to transplant into 3 gallon plastic pots. I am also going to change the light source to a 400w MH and 400w HPS. Would it be ok to do both of these at the same time? Or would it be too much stress for the plants? Rating: 5
