Starting indoors and finishing outdoors

I've gone 14.5-15 hours length of day for years and growing in a few different locations, but daylength depends on your proximity to the equator, and whether you're in the Northern or Southern hemisphere. Typical outdoor start here in Ontario is end of May, usually on or right after the May 24th weekend. That happens to coincide with both moderate temps where you typically don't have to worry about cold nights, and the day length.

Reason I say after 14 hours is from time to time I've done 14/10 cycles indoor to get my plants pre-stretched before going into my flower room. Most will just stretch and start pre-flowering but several strains have started full-on flowering in that cycle.
Yep, you guys up north have crazy long days in the summer. {although you pay the piper for that in winter} Here in NW Florida, our days are not as long in summer, but they don't get as short in winter.

I had always heard 13 1/2 hours was safe, but these days with the early strains, they can be touchy as hell. Last year when it rained 21 straight days in June, all my shit started to flower.

I'll put my older strains out first, then the newer stuff as the season progresses.

Yeah you got it, if you know the strain you can adjust one way or the other. A lot of variables so if someone's asking I'll typically suggest the safe route for suggestions on timing.
