Yes, the right bulbs are in the T5's and I have grown from veg to flower with T5's successfully before. What happens is that the yield isn't bad with the T5's but then again, if you aren't also running HPS on the same batch as a baseline, you never know what yield loss you are suffering. The same seeds, veged 1 month under T5's and then 4 of them taken and put under an HPS. The growth in the ones under the HPS was much better. They doubled in side shoots and buds under HPS.
