Force flower white widow

I have a question, I live up in Canada and I have 2 white widow plants growing inside pots under the sun right now but it's still to cold to put out. Now the flowering time of white widow is really long which doesn't suit my climate because we dont get anywhere near 12/12 hours of light until its almost freezing at night. So I was wondering if before I planted them outside, i gave them 12 hours of light and 12 hours of darkness and they started too flower, could I put them outside and they would still flower even when i'm still getting about 18 hours of light outside.

Thanks

This is a very important lesson about outdoor crops.

Plants do not start to flower @ 12/12 outside.

They flower way before then. Like the middle of August where I live.

Outside plants know when the days are getting shorter, and when it gets short enough the plants are triggered into flower by their hormone levels.

This happens at about 14 hours of daylight, not 12. But this can be strain specific. Some will flower will less light some with more...

Now, white widow is an Indoor strain. So I dunno how well its gonna do outside. And in Canada you have a shorter season then I do.

you could always just bring them in at night, or put a black bag over it to block light.

Yes, this should work, although I'd try it a little bit later in the season than right now... perhaps start covering them in early-July for a mid- September harvest or mid-June for an early-September harvest. You could do it now, as well... just make sure that they are pretty well along in flowering before switching from the 12-12, or else they could revert... I'd give them at least 3 weeks, maybe even a month on the 12-12 before releasing them to the full intensity of the sun.

Do you mind if I copy and paste this from now on instead of typing it out over and over again?

This post should be a sticky. ^^

By the time the light gets to 14/10 where I live it's August 25th and our first frost is September 15, Ive also seen half a foot of snow in late September and it hit -10 C at night.

So how long do i need to cover my plant at 12/12 so I make sure it won't revert back to vegetative? Would 3 weeks work?

Yes, if you're going to force flower, then three weeks should work.
