Outdoor Spring Grow and Day/Night Cycle Question

If you put a plant for outdoor grow right after the last frost, say on March 10 - 20 (this is when D/N ratio crosses 12/12 for most of US), how long will you have on a pure D/N ratio before the plant stops flowering and goes back to Veg?

Seems like you would have a month or more where the D/N ratio was transitioning through 13/11 and then 14/10. Lets say you put them out on that solstice day or w/e of exactly 12/12 and they were Vegged indoors approx 4 weeks and ready to flower, what would happen? Will you get any mature bud to smoke by say April 15 or May 15?

Depending on location, D/N will not cross 14/10 until about April 10 - 20. Will plants still be flowering around that time? Or put another way, what will the D/N ratio have to be to stop flowering and send to veg? Is it 14/10, 16/8 or 18/6?

And I am sure a bit of it depends on the strain. Maybe this is why Autoflowers are so popular, for a spring harvest no matter the D/N ratio?

That was very confusing :confused:. Dont put them out too early encouraging early flowering ,reveg then flower again, it reduces the final autumn weight. Put them out after april 20.

It still might rain ,under a cover or in a greenhouse provides protection. I would just put little clones out or sick plants right now. In pots you can move them under an awning but in the ground watch out for late rain and mold.

18 hours of day light, where you're from Alaska? ;-) in my location just like your's, 13 hours of day light is reached around 10th of april. longest day of the year is 15 hours and 20 minutes long. equator days/nigths are always 12/12.
I'm really no expert here, but my guess is that too early of planting could only stress the plants (flow-veg-flow???). but I don't know how early it is so they would or wouldn't start flowering. I'm interested in that too. my guess is that other things like temperature, sunshine/rain and strain also play some part. plus you can count on it that plants feel spring and day lengthenig, they will flower when they will want. it's different than indoor. nature is a funny thing. even if you had some bud in spring it would be 10g instead of 200g. are you sure autoflowering strains are not what you're looking for??

I have heard of people putting clones out really early and being able to get an early harvest off it in spring, then have it re veg to have a second harvest from it in the fall. I see a lot of people putting clones out in early spring and they start budding out. I think its anything below approximately 14 hours of light each day will begin to trigger flowering. You can start seedlings much earlier in spring under natural lighting. Seedlings, unlike clones, are not sexually mature until they reach a certain age, approximately a month before they could even begin to bud. I can start my seedlings in mid april and not worry about them budding out. I do not put clones outdoor until end of may, to prevent them from flowering early.
