hey y’all i’m about 2 months into a grow, gonna switch to 12/12 soon, but first i’m swapping in a 600w Cree COB LED array to replace a 180w fluorescent setup i had for veg.

dude who sold me the light said it should be 3ft from the canopy, but i’m working with under 5ft total clearance in my crawlspace.

everything i’ve read online says 20-26” should be fine, but now i’m pretty worried about frying these plants i’ve been working on for what feels like the longest winter ever....

Might need to dim them a bit, can take time to harden up from flourescents

ok word. i topped and have been aggressively LSTing for a while to keep my plants as flat as possible, so right now i’m able to get about 26-30 inches between the light and the canopy. do you think that’s enough distance to harden them up without dimming? (i’m not sure it’s possible to dim the output with this Meanwell driver)
