Grow LightsIs 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-vegLeaves. Tips - Burnt

Auto and regular plants in one box.I got an auto plant in a box, waiting for flowering to start very soon. Light schedule 20/4. Now I planted a new photoperiodic seed in a same box.

My grow tent is sitting in my basement, which normally sits at 10C in the winter, so I set the heat in the room to 18C and the LED and 2 fans heat it to 20.4C in the tent.
Anyone have a similar setup but using their grow lights as a heat source? Heating a basement is expensive.

Do I keep dimming my light to try to get proper DLI?Currently at 22" above soil at 50% intensity and still getting ~50DLI at Germ/Seedling stage (too high?). It's a 240W LED. Do I keep dimming the light or do I change light schedule (24h currently) to get proper DLI?

Slow indoor seedling growth4 days since sprout, issues with light timer, seedlings ended up getting 48 hrs of light after they sprouted, and this AM I found that the timer did not turn the light back on so it got 11 hours of dark last night instead of 6. Could this be detrimental to seedling?

Floodlight for bloom supplementI have read that my vipar is not the very best for bloom. I want to encourage and support the flowering with my philips 50w 4000k floodlight, what do you think, will this make a worthy difference? (Until I get a new all arounder light)

Can I switch my lighting schedule ?Hello everyone. 1st grow here. I'd like to swap my lighting (automatic plants) from [4am:midnight] to [4pm:noon] just to keep the temperature a little higher at night. Is it doable while not hurting the ladies or should I shift it an hour per day to change the cycle ?
Thanks !Setup. Lighting
