T5 grow light help

What brands or features should i look for in t5 bulbs and will they work the same with a regular 4 ft florescent light fixture?

I use pioneer t5 fixtures and swapped out every other bulb with power veg bulbs they won’t work in a regular fixture like a shop light if that’s what you are asking

I was not sure about that. I have plenty of those florescent 4 ft shop lights and was hoping to use them but no big deal ill just get a whole light. Thanks gardenguy

you can use one or two of those shop lights for germination and seedlings i think, if you have the room to spare.

The ballast inside of the fixtures will usually indicate which bulbs are compatible. Most of the standard shop lights are t8, not interchangeable with t5.

T-12 and T-8 floro tubes will veg plants great,
the bulbs have to be very close to the plants tho,
T-5 HO allows a little higher hanging height.

r u needing T-5 just for veg or for veg and flower (germ to jar).?


I have two of these t-5 lights for veg. and upgraded both with powerveg bulbs and I like the results. I do have a set of bulbs for flowering I can swap to if I need to flower in the veg. room.

with the powerveg bulbs

This was taken at day 14 of veg.

Just for veg for now may try them for flowering down the road how well do they do for flower with the correct bulbs

they can flower good if u keep the canopy only 8-12" deep,
it takes 60+ wpsf to flower well under T5 HO,
a 2x4 area needs 480w-560w of T5 in flower for great colas,
where as 216w will veg the same area.!!
a 432w 8 bulb 4’ T5 HO for veg will allow the lights to be a bit higher, like ntmaremach has in the pics above.!

I use a Quantum BadBoy T5 with Eye PowerVeg lamps and average 200 grams per White Widow Autoflower. I use (4) Full Sun + UV and (4) lamps in the blue 400 series. I change to 600 series for bloom (reds).

HO T5’s can grow great weed with decent lamps… not my first choice in lighting but still, they work :+1:t2:

Happy Growing!!
