3200k my personal or 5000k a mixture of both would be Ideal I don't know why you would want to only chose one though. This is all LED based I assume are you counting MH bulbs they can be very good for vegative growth just expensive to run.

Light distance for Seedlings
My question is my 2 seeds have popped out and I am using 3- 8.5 watt 5000K LED lights to light them up. Both plants are under humidity domes so how far should I put the lights above them? I have them in a make shift grow tent for now as my regular tent is finishing up a grow.

24 or 18 and 6
Been running my lights 24 hours a day on my seedlings. Since I am growing autos, should I be at 18 and 6 now? Or should I keep running them 24 for the first couple of weeks to help veg up little before giving rest? This is my 1st time growing autos and 1st indoor grow in 20 yrs

Can I change my autoflowers light cycle withou reducing their yield significantly?
I am having humidity/mold problems and was thinking of changing the cycle so the grow goes off at noon ( currently it goes off at 1am and its winter and gets real cold with 88% humidity). Even if I stress them, it would be better to not have mold than reducing the yield, right?

Kind LED XL600 series 2 heights?
Hey, I’m running 2x Kind Led xL600 series 2 lights and seen people running much much lower hanging heights than recommended (18inch instead of 30inch) and wondered if anyone has any PPFD or PAR readings at anything lower than 30inch or any reasons why they run them lower. Thanks

Switching from led to hps for flower?
Howdy, does anyone switch from a blurple led board for veg, to a hps or similar style light for flower? Why, why not? Is it worth the little extra hassle to buy and install? I like my led just fine, but wondering if there’s more to be gained in flavor, quality & yield. Thanks!

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
