My cobs are running 70% output about a foot from the canopy.
I haven't seen any bleaching. Well. That I've noticed.
And yeah. Old/budget led tech sucks. Despite LEDs being directional lights. They can't quite throw photons as deep into the canopy as hps,mh,cmh,etc.
Even a hid light can bleach plants. Having too much light and/ or too close a light will do it.
I honestly don't know man. I cracked it at the water only method. And moved them all into the cloner.Sweet so your older clones rooted?
Cheers. I think I'll get a decent amount this time round.gd luck
