Cloning area lighting
I have a 4x4 tent that has 2 plants growing, and 1/4 of it I wanna create a little box that light cant get out if for clones to grow, and set an LED in there. If I take clones, set my main plants to flower, takes 4-6 weeks, how much light is needed for the clones to survive?

Changing lights for auto flower
At the beginning the light schedule was 18/6 after 2 weeks I changed it to 24hrs because the light was too weak (10w) I now got different stronger lights (600w)(finally arrived) With the stronger lights can I change it back to 18/6 ? It's autoflower.🤔🤔

Alright so this morning from 8am to 4pm my power was out. I transplanted last night and soaked the medium pretty well. Will this power outage hurt my girls. Did the temps being 10 degrees lower all day hurt them. How soon will I know if I get root rot or anything of that nature?

Currently running my KingLED 2000 with both Bloom and Veg switches on. Is this the correct time to go just with the Bloom lighting? There's no harm in running both throughout; correct? Except to the power bill of course. Any thoughts?

What lights for a 2'x3'x6' tent?
What light or lights for a 2x3 footprint? Veg and flower. Deciding between 2x Viparspectra XS 1500, 2x HLG RSpec 100, or a combo 1 of each. Budget is 200-300ish. Cheaper is better. Open to suggestions. Not sure if I should have 2 of the same lights or mix n match.

Light hanging distance
I’m not sure how high to hang my light. My plants seem to be all staying extremely squat and not stretching, though all seem healthy. I’ve been fiddling between 18-28 inches and 600-800 ppfd (ios meter app) and I can’t find a distance that seems to make them happier. D26 autos

Is this enough? 2 mars hydro 600 TS or 200 watts of led in a 24x24x36 tent,
Using a 24x24x36 tent, I have 1 mars 600 ts (100 watts) in there for one plant. I’m going to throw another mars 600 in there as well and grow amnesia haze with my northern lights. I have good ventilation, will this be enough wattage or should I get some CFLs for under canopylight
