T5's work great, but they need to be super close. Quantum boards penetrate a lot deeper into the canopy. They don't have the UV unless you add it, but they kick ass.
use what you like I'M not trying to convert anyone. for me T5s work great and they are popular enough that they will be around awhile
Great looking plant!! That main cola is
For flower cycle I'd say no, maybe with side supp?...... Look at the umol/s and that's with China marketing bias.
Iplan on using them as supplemental lighting to add more red during flowering.. eavh bulb produces 132 umoles at 12 inches so 4 would give you 524 umoles an efficient flowering level. my main light produces a little over 700 umoles so flowering power is not a problem
Those are spot measurements for PPFD. 168 watts of those lights do not have a PPF output of 524 μmol/second. It will be less than that, likely a lot less.
I'd lean away from them imo...... but It's your money, only one way to find out grower
we don't learn without experimenting
