    100W CXB3590 vs 100W LM301H QB

    What would be better for my 2.3’x2.3’ tent? Single 100W CXB3590 3500K chip with lens or LM301H 3500K QB? Thanks for all advices. Edit: I own the single chip CXB3590 light, and it works really well, just want to know if it’s worth to replace it with QB.

My first bar...

    CXB3590 6500K, 5000K, or 4000K for 4-5 week veg, with moderate LST?

    I would like to avoid too much early stretch, as the girls cannot get much taller than 4 1/2 feet from top of soil, when flowering is complete. I do plan on some moderate l.s.t, to keep them fairly short to max out yield and even out the canopy. My flower K rating of the same model is 3500K...
