I would also like to add that even though the 4ft T5 bulbs emit 54 watts or whatever of light, they are not emitting from a single point light source like HPS bulbs do. Therefore the intensity is going to be much much less. The light is spread out across a 4ft area. Moving the plants closer to the T5s will make up for the lack of intensity. I just flipped one of my plants under 2 red sun, 2 fiji, 4 flora sun to 12/12. Will see how the buds compare to my monsters under the HPS. Unfortunately all my monster buds got pollenated. The cutting I got must have been a mutant. I'm not sure what they are doing over seas with these strains, but it sure has been creating a lot of hermies. I'm off to go search for a cutting that is pure 100% female. No more of this mutant hermie trash. It's possible the HPS had something to do with the pollenation so if it happens under the T5 I know that it was just a trashy cut. I'm pretty down about it because the one plant I had flowered got a LB off of it. Now it is riddled with tiny hard seed crap.
