The size difference is the ones under the T5's are about 8 inches taller than the HPS. However, they experienced the tremendous growth under the HPS not the T5's. I felt bad for the ones under the T5's so I switched the whole batch around. I have always grown thru flower in 3 gal but for some reason, as soon as I replanted into the 3 gals, about 4 days later the roots where coming out the bottom. Thats a first for me. I have been putting off going to the 5 gallon because then I would not have enough light. Only 1 400w HPS and 1 8bulb 4ft bank of T5's that is 2 ft wide. I will try adjusting the ph first and see if that does anything.
turksteelman Reviewed by turksteelman 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
