Flowering lights never turned off
Power outage messed with my system and lights didn't shut off. Need a little advice. Should I just stick to the original schedule and she will just get 30 hours of light for one day or should I turn them off.

General question about raising lights.
Gotta question for what most of you are doing to raise your lights? Currently I've just set it static and move as needed. But I'm curious if anyone has a easier method or know of anything made to aid in the raising of the LED light fixtures ?

Trying to get setup right
I know I prob need to get a nicer light and ditch all the crap lights but for now I have what I have. Perhaps after some success I may be able to get a new light to replace all of them. But how far should it be? 2 feet above rockwool cube? And what watts per plant

Should I substitute sunlight with a grow lamp on cloudy days?
It’s overcast here today and I’m wondering if I should turn my grow lights on to compensate for the lack of direct sunlight. If so, should I drop the intensity to compensate for the additional natural light? Can you overdo the amount of light (not heat) a plant gets?

Light set up.
My only question i have is about my light set up. My plants are 7 days today and i noticed that my plants are all facing towards the light. I have my light at 60cm from the top of the plants and 75% on the dimmer. The light is also 1000 Watts. The tent size is 4x4.

Add on lighting
Hey Growdiaries. I’m about to start my 2nd grow but I’m not happy with my Viparspectra 300 for flower. I want a cheap add on for the flower stage? CFLs look like a cheap, low energy use, add on as I’m only growing two plants in a small w3xd2xh3 ft tent. Any advice plz & 🙏🏼

LED Kelvin Temp 3000k-6500k
Is there a massive difference in colour temperature/kelvin of LED's if the lumens, PAR, watts, intensity and every other aspect you can think of is the same but its temp/kelvin is lower? I use a 6500k LEDs, may mix in or switch to 3000K for better flowers if its proven to work.

HLG UVA supplement
Introduced this hlg 30 uva light as a supplement to the twin 260s. I've read just 3 hours a day increasing 1 hour per week up to 4-6 hours before harvest. Anyone recommend anything differently or just run it 18/6 with the lights?

Can a 1000w LED grow light be closer than 60cm (24") to a seedling?
Different sources are saying: 1000w LED light should not be closer to a seedling than 60-75cm (24"-30"). The seedling should be getting 5000-7000 lux, 100-300 PAR (PPFD 18h) and 12-20 DLI. Question: Can I put the light closer at ~40cm, dimmed to match the needed lux, par and dli
