Change lights off time?
I'm having trouble with temperature control. My nights get too cold. My current lights off time is 12am-6am. Is it possible to change it? I really want my lights off to be from 9am-3pm. I think that would help me a lot. How do I change it? Let my lights run for 27 hours?

Wow. Thank you so much for the reply. I have been playing with LUX meter app and my light. I was bit skeptical about the lumens that I would get from the 15W but as it turns out, it receives well enough ppfd. Still skeptical about the spectrum i am having.

About the 1200w light
So I did already in fact order the 1200w led light for the 60x60x140 before asking for advise on it, which was stupid of me. Is it possible to use the light with the door open and fans to decrease hot points?

Light schedule
I am doing an outdoor grow and also have a grow room set up for germination. Outside is only getting about 14 hours of light, is it beneficial to bring my girls in under my LED's for 4 hours to make sure they're getting a full 18 hours of light? then bring them back outside

LED distance to plant advice
Interested in how close I can get my 630w LED with a rating of 2.7μmol/W and 1700 PPF to my canopy. I had it hung 48cm (19 inches) on 380w and just upped it to 500w day 8 in flower. Does this sound too close at 500w or is this ok? Temp is 25C (77F) humidity 55%.

Shifting outdoor plants from outdoor to indoor
So I was wondering if outdoor plants(week 2) getting regular sunlight (~12-13 hours) can be shifted indoors for faster growing (18/6 or 24/0 or 20/4)? Anyone tried before? it is safe? Will it cause to make them hermaphrodite?

Grow light question
I bought a cheap light by KingLED. It’s only 100 Watts and I’m unsure if it’s enough for one plant. The light has 2 switches, one for veg and one for flower. Should I always have both on since it will be an autoflower?

Swapping day/night light cycle during flower
Day 22 of flower. Lights are on during the day, 8am-to-8pm but we need to switch to 8pm-to-8am to use the colder night air to cool our lights without using a/c. Would it negatively affect the plants at this point in flower to give them 24hrs dark & completely swap light cycle?

Is this light good enough?
Will this be enough for 2 auto flower plants in a grow tent? Or will it work for one? The tent is 20x35x64. Or should I get another one or a different light altogether? Thanks!!

How to switch to flowering
It's been about 5 weeks from germination. I think we're ready to switch to flowering. I'm just not certain on how to go about it. Do I gradually reduce 18/6 of the veg light down to 12/12 (over a week?) then pop in the flower bulb? Or do I just make a hard switch?
