@gorillamotors Just things that I've heard; no real knowledge from my own experience... the high output t5 bulbs are like a 1/6th to an 1/8th of the cost of the full spectrum bulbs, but are very close to the same light spectrum and the overall output in a side by side comparison is minimal. Like 10% better on the full spectrum grows, but way more expensive. I'm not experienced enough to really site he stats, but I'm willing to hear em if you feel those are way better and my cost function is wrong.
