Why wouldnt you lst (at least slightly) while using T5s?
Im not trying to come off as douche but i have a few questions for you.
Why did you use t5s? Were you really pressed for space?
6oz= 168g. 400watts*(.42) = 168, so nearly .5 gpw not bad
But it took 18 weeks? Holy shit you're patient. I'm asking all of this because im on the fence btw a 150, 250 hps, and t5s.
From what ive gathered hps is going to pack on the weight, and it seems more lumen efficient, however its going to cost you in fans and electricity. T5s run warm (vs hot, but only because they are not single source like hps) so I suppose you can get them closer and make up for any lumen gaps, you can also use all kinds of PAR specialized bulbs to hit sweet spectrum spots like a kungfu expert.
So what's the deal guys? HID lighting is to vikings as T5 lighting is to ninjas
I would LOVE to hear more information on t5 yeilds, as hps yields are very easy to find online. But from what ive seen, its much easier to press .6gpw > with hps than it is with t5s.....
