How to measure lumens of a full spectrum LED light.Since a lux meter only measures certain spectrums of light, how do I use a lux meter to determine the right height of my full spectrum grow light? I have it at the recommended distance but I have signs of light stress. Bleaching of some upper leaves. I moved it up 4 more inches?

Grow Lights Is it okay to use an LED Light 1000 watt (4x4x80" tent) & a UV Light 1000 Watt in a 4x4x80" grow tent for 3 plants. I want more light, I have plants growing slowly so I'm hoping to adjust the amount of light I have would speed up their growth. LED is white spectrum & UV blue-veg

How can I reduce the heat in my 5x5 tent (650w light bar/6" ac Infinity and a ton of fans) without AC? Do I have to leave tent open?5x5 tent is in a kind of lung room (utility room) that stays around 20C/68F. The tent always seems to be at 30C86F with lights on. Ive added and moved fans, opened more intake vents. I have AC, but its -25C/-13F outside. Id like to drop the daytime temp 5ish degrees for flower.

How much light - PPFD - without CO2?How high in power should I go with my lights without CO2 enrichment? I can comfortably provide 1200 PPFD to the canopy, but I'm holding it down near 900 because I'm not sure the extra power used would yield an increase in, um, yield.

Back To 24 Hour Light - Auto Flowers My autos switched from 24 hour light to 16 about 2 weeks ago to see if it would help make them bloom faster. Can I turn them back onto 24 hours or could that mess things up? I would like the most amount of light time. They should have 2 more weeks left
