Confused with light schedules for outdoor growing
Hi fellow growers, I'm really confused with light schedules for outdoor growing. Everywhere I see 18/6 for veg and 12/12 for flowering. However at my place I get ~13hours of daylight (not always sunlight) Would my plants get into flowering if daylight is reduced to ~11 hours?

Changing light cycle on seedlings?
Can I run autoflower seedlings under 24/0 light cycle until they reach mature veg stage, and then move them into an 18/6 light cycle? I’m starting seedlings in a space tote, then transferring to a large tent to mature. Will the light cycle change have negative consequences?

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%.

regarding the light spectrum ratio. what is the ideal light spectrum for both the vegetative and flowering phases? Do you use 3500K lights during the vegetative stage, or only use cold white lights at 6000K? do you then switch in flower to 3500K lights along with 370-780nm?

How to reveg plants after preflowers by the end of april outdoors?
How big are the chances to bounce the plants back to veg after preflowers by the end of april and 14h of day length? Mostly cloudy weather, warm day temperatures (30c) and cooler nights (8c)in the old greenhouse simulated probably to much end of summer vibes.

Lights for heat- 24/7 okay?
I really need the heat of the lights to keep the inside of my tent warm. To warm the air around the tent 24/7 would be expensive- much more expensive than using the lights all the time. But will this work with 24 hour lights? Will that stress the plants? Using auto flowers.

When to switch LED to 100% power?
Another question. I appreciate everyone's response to the last ones. I am finding it difficult to google this one. When do I switch my LED to 100%? Currently, I am running it at roughly 60% at about 24in. Am I in 'true' veg? Its working on its 3rd node that has 5 fingers.
