Question about starting plants this late in Colorado.

I recently got 12 1-2 foot tall plants that I've set outside in my greenhouse in Colorado. Right now I'm getting 14 hours and 56 minutes of daylight give or take a couple seconds.

Last year I did this but the plants had been set out in May, and flowered in mid august. I'm worried this time though that these clones will flower early.

So my question is, will these plants start to flower? I'm pretty sure they've been under 18 hours of light since being rooted.

Clones are Grape Ape, Purple Train Wreck, and something called Hollywood.

~Thanks!

Bump! Any advice? I am wondering if I should put lights out there and just do supplemental for couple hours a day.. Would really appreciate any info.

I need this stuff to last awhile, so I think I will do some supplemental lighting, I'll post pics tomorrow.
