Will this 4 bulb T5 HO fluorescent fixture provide enough light in grow tent?

Not sure what reality you live in, but it's a simple fact that T5s, cfl and led cannot produce the same lumen output as HID for an equal amount of energy consumed.
High lumen output increases resin production and all around performance of the plant.
You could not be more wrong, lumens mean absolutely nothing to plants, tis a measurement for how humans "see" light

WOW. I'll agree that there's a certain point at which the plants stop taking in light, but that point is way beyond the lumen output of T5s.

I've been flowerin with T5's for years LMAO
I didn't say it can't be done, hell I veg under 432w of T5 but sure as hell ain't gonna flower with them and expect a decent yield or high potency. Outdoor is nowhere near as potent as indoor, wanna guess why?

I use 1000 watts of T5's in an 18 bulb setup (clic sig link) all I care about is potency, yield means nothing and yet my garden yields just fine

Have you personally compared HID to T5 side by side? I'll bet you'll switch over if you ever do. I'm not slamming T5s but the heat from 18 of those bastards with no inline cooling would be unimaginable for me.

Actually newer t5 with newer ballast are very close to hid. Withinn a few % of being the same efficiency of single ended hid.

T5 produces a better product in my opinion.

They're a pain in the nuts to keep cool tho. HID still puts out more lumens, easier to cool and penetrates the canopy deeper than T5.

How far do you need to penetrate? The will put out about the same heat for equal watts.

Lumens mean nothing.
