my 2 cents get some UV into your room 2 or 3 weeks before harvest, stimulating UVR8 receptors will make a difference in end quality.I do want to get myself a uvb strip tbh it’s something I’ve been looking into! Just more on the chlorophyll atm , I’ve been pumping the T.A fulvic acid at max doses ( 2ml ltr ) and will be stopping that very soon, but will be continuing to use the mills vitalize slicic acid at the lower dose of 1ml per 10 ltr up to flush,
