Transfer to greenhouse

[asum]

I just transferred some thai stick from under lights that were at 18 on and 6 off, right now we have just over 14 hours of sun, my question is by moving from 18 hours of light to 14 hours will they go into flowering. I have not did this before and was curious.

Autos will do what autos do. Photos should be ok....

welcome aboard!

I’ve flowered indica strains at 14 on and 10 off before. A sativa should be ok at 14/10 for vegging. Some of the Thai Stick plants I’ve seeen lately don’t really look very sativa though. The age of the plant matters too. If it’s only a couple months old, I suspect your fine. If it’s a root bound mother that’s 18 months old, she’ll look for any excuse she can to start flowering.

I would be careful doing it if they are reasonably old and well-established! Photos should be able to still keep vegging under 14 hours, but you definitely want to slowly reduce the light schedule until you are matching the outside schedule

I had a bunch of clones (some big and established, some still cuttings that were rooting in little solo cups) that went from 18/6 in a tent to 14.5hrs of daylight outside, and because I didn't gradually reduce the light, they started flowering... Every. Single. One. Haha so that was some work to get everybody to switch back to veg

They were a few different strains, but mostly sativas

In my area I wait for 15 hours of light. In my experience they will start to transition with less.
I try to run my plants that are going outdoors with the same light hours as they will have when I put them out. Always 15 for me.

I may have rendered a bad opinion on the outdoors thing - can we see a pic of what size the plants are?

They are less than a month old but are close to 24 inches tall really healthy looking plants, have no pics, I'll just keep a close eye on them.

Reduce your lighting gradually or just wait another week. I put plants out about this time last year and they were fine.
Growing season in Thailand is pretty long.... a real Thai strain wont really do well unless they have a long flowering time. Thai need to be tamed back with some indica genetics to get a reasonable flowering time (+90 days 120 is preferable).

They are hard to grow even in a greenhouse for that long flowering time.
