Flower about a month under lights, then move outdoors?

[Tijeanster]

I have trouble getting photos to finish with my local fall weather. Thinking next summer to have a couple of plants flipped and enough flowering time under lights then move outside sometime past mid July. I am about 47 deg. N . Dont know how close I would have to snch. the daylight hours so they dont revert to veg.

Is it a crazy idea or is it something that is done.

Sounds doable, I would get something that has a short flowering time.

Auto flower strains for outdoor.

Light deprivation is probably your best bet for photos Could start pulling a tarp (or setup an automated retractable covering) in July, every day for a month or so, until mid August. By then the hours will match the same deprivation schedule, so you can quit tarping them off the rest of flower. They'll be halfway done already, and starting to stack before they would naturally start flowering without light depping. Finish a month early, when the sun is still high

Thanks for the input; sounds like it would be an over complicated experiment. Do-able, but not simple! It is easier to put light on than it is to keep light out!

I’ve seen many greenhouse growers that use light deprivation blackout cloth to force flowering early outside. Without a greenhouse it would be a pain in the ass, but it is doable.

If I already had them flowering for a month inside, it would be a matter of preventing them re- vegging. Would they need the same degree of light deprivation to hold them? I expect that different cultivars may have different precise day length figures to trigger them. Tales of "light poisoning" spooked me

If you matched the hours of darkness it might work

I veg under lights; then move outside to flower. (I use the gas lantern technique to veg them for a few weeks longer once moved outside.) But you're already flowering under lights? I guess, I don't understand why you would want to move them out now?
