One t5 one t8 florescent tube lighting?

[en4cer21]

Ok forgive me if this is already on here somewhere,but im getting a two florescent bulb fixture and im thinking of having one t5 and one t8 florescent bulbs. Im wondering if this is good for growing from start to finish

Fine for veg and can produce buds, but not at all ideal for flowering.
Why 2 separate fixtures? Doesn't sound like you are doing separate veg and flower areas.

I was going to use 2 t8 bulbs but then I seen a lot of people on here using t5 bulbs so I thought maybe using both but I thought I'd ask first

If it's all you can afford run it all way through to harvest. If you can use LED. I had T5 it's hard to keep temps down, even with proper ventilation. Leds are much cooler and it's a hassle adjusting lights everyday just about. My T5s burnt the leavesyo close. An was hard to keep even canopy. I'dsay if you grow photoperiod an keep topping you'd get huge yield, depends how good you use it

T8

I dont think t8 bulbs will fit in a t5 fixture(at least the ones I am using) if you could get a T5 Fixture with some H.O. Bulbs it will be more efficient then T8 but I don’t think by much. But with that being said T8’s are more available and easier to find, at least where I am at. A lot of the bulbs come in a 2 pack any ways so if it was me I would use the same for both bulbs.

I’ve had good luck with the Sunblaster 6500k T5 H.O. I use 4 of these for veg and when it’s time to flower I put in 2 softer ones to widen the spectrum I think the softs are 2800k.

Not understanding the reason you want two different bulbs.

I used T8 LED ballast bypass tubes and rewired the fixture. Less power and heat, about the same light. MIne are 5K.

T5 HO's work great if you know how to use them.

I don't want 2 different bulbs I was simply curious if two different bulb types would give different benefits from both and if anyone has tried this if so what was the results

You can get different light spectrums with the same type bulb, from 6.5K to 2.5K, that is where the difference comes in. T5 HO's are higher wattage, but need a specific ballast to run them. T5's are smaller diameter, so more can fit into the same area.

its rare these days for anyone to use shoplights or even T5's

but with patience you can get a better grow outta these than even the more popular LEDS

one or the other My preference is for the T5's about 30% more heat over T8's but to many on here thats not noticeable

go either one or the other and duel T8's /shoplights are cheap as chips to buy and use too

hang from chains in a tent or 3x4ft closet, adjust daily to hang within an inch of the leaf tips

VIP/ to ensure at veg you use 50% cool white to warm white for correct vertical growth

later in flower switch out the cool white to go 100% warm white also remove all lower laterals

as the light don't reach that far and makes great ventilation use the scarps as clones

good luck

Thanks that helps a lot i really appreciate your input

T5 HO 2 spectrums

actually we never used those over priced 'grow' lights as the tubes were 30% more expensive and 33% less effective than typical office lights ..lol

ensure you have a good mix of tube kelvin of warm and cool shites

to get them lights to really shine

you can double the ballast so each tube has 2 ballasts

for 2x as much light tho it does make them burn out 2x as fast

same trick can fly with CFL's tho tricky soldering an extra tiny ballast to a cfl

good luck
