Happy St Patty's Day!

I have these plants, all of them are photo. Some have been started from seed some are clones. Right now they are under 15 hours of light and 9 hours of darkness. If I put them outside and I am only receiving 13 hours of daylight will they start to flower?

You can also put them out earlier and put lights around them for a few hours at night to make sure they don't start flowering. I did that with a single plant a few years ago, and it worked just fine.

Did you wait until June?
I'm in a similar situation. I'm running 18/5 light cycle and planning to reduce the daylight cycle by 30 minutes a week until I'm at 13/11 and then put the plants outside mid spring. I'm hoping if I do it gradually half an hour per week instead of a big jump from 18-13 then the plant might stay in veg. Also the plants are unfeminised so if they did show signs of going into flower in this period it might help me to work out which ones are female and which are male. Just interested to hear what you did and how it went for you?

I put them out in mid May, 14 hrs 50 min of daylight. All but 1 clone had powdery mildew. The one clone I kept is doing great in flower. All seed starts are fine. I post pic tomorrow.
