Back To 24 Hour Light - Auto FlowersMy 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

Lifespan of led grow lights?Lifespan of LED quantum boards?
Hi
I'm looking for anyone who has first hand experience with the lifespan of the led grow lights. I'm not looking for the manufacturer guidelines. Just anyone who has noticed any difference in performance from the LEDs over time..

Lightning questionHey, Growers! This week I had to open together the two boxes, so now all the plants have both kind of lights. Do you think, it can have a negative effect on them, or maybe it's good at least for the 140cm height White Widow,because the bottom parts get some more light from there?

Колличество светаCan anyone explain why all the guides and manuals say that autoflowers need 500mmol/cm2 during flowering while photoperiods need 700, when in reality, under sunlight, the plant in the wild gets 1400-1600? Why not give the same amount of light to plants indoors?Week 9

regarding the light spectrum ratio. what is the ideal light spectrum for both the vegetative and flowering phases?
Do you use 3500K lights during the vegetative stage, or only use cold white lights at 6000K? do you then switch in flower to 3500K lights along with 370-780nm?

Do you lower light intensity and temps towards the end of flower?So I’m in mid flower, start of week 7 to be exact. I’m curious on when you guys start pulling back light intensity and going with a little cooler temps. I’m running a 240W S33 from AC infinity in a 3x3.
Should I be going strictly off of PAR or VPD at this point.Setup. Lighting
