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?

Contemplating putting 2 plants outside. I have 8 in a 3x3 with Mars hydro tsw2000. It’s pretty tight in there. What do you guys think? Is 8 too many for the size and light? Or should I just leave them as is? I think the the pots are 3 possibly 5 gallon.

Temperature VS More Light which is better for buds size and potency
Should I continue to use two LEDS if temps are reaching 87f during flower (day 1) or just move plants more towards center of tent and use one LED for better temperatures (75f) (only growing two plants). lights are 1000w bestiva and are in a tent that is 24"x48"60".

I’m here again with another silly question Or not I’m not sure🤣 I have a 600w ballast with a 600&400 switch on it and I’m wanting to downgrade to a 250w lamp. Will my ballast power it okay or will it kill it🤔 or should I get a 400? Thanks!

raise lights during stretch?
Should I raise the lights during flower stretch to maintain the same distance from light source to canopy? I notice that my plants continue to get taller than most. I know the stretch is natural, but I'm wondering if constantly raising the lights with growth is the right approach

Less light for an auto? Maybe 12/12?
Been going with 18/6 for my cream autoflower from growers choice from Day 1. Now 5 weeks into flower I’m wondering if she would benefit from less light, like 12/12, as you would for a photo period plant. What do you think? Would she be happy flowering in some more dark period?

Lights for auto plants, very low budget.
I have a 250W CFL 6000K for small grow tent 1.75x1.5m First do i need a 3000k bulb for flowering? If so, i was intending to buy normal LED bulbs instead 1 big bulb. About 6 to 10 bulbs 15w 1400lumens each bulb. My question is, am i going for much worst than with the single CFL
