Since most of us start our summer grow indoors then move to outside in May, I'm curious how others handle their lights schedule to avoid the problem of plants starting to flower when they're transitioned to outdoors. With Indicas and hybrids it doesn't seem to be too much of an issue but the last 2 summers I've tried Sativas outdoors and they seem much more sensitive to light schedule changes, all of them stretching like crazy and one even going into full flower in early June, even though the night length was <10 hrs when they were put out.
After experiencing a huge stretch in May last year I thought I'd be clever and start the girls indoors mid-April and move them outside while they're still immature. My thinking was that the "stretch" is tied to sexual maturity, but no go. No flowers developed but tall, spindly, stretched plants was (again) the outcome.
I assume the best way to avoid this is to keep them on a 14.5/9.5 schedule from seed, then the outdoor dark hours will equal the indoor schedule when they're put out and they should just continue with a normal veg. Alternatively, I guess I could just start them outside in a greenhouse and let them deal the weather, but not optimal growing conditions.
I suppose it doesn't harm anything, but right now I have 3 8-foot girls in the garden which doesn't do much for stealth and makes it a bitch to manage since the tops are so high. What do you all do?
