One of my strains went into flower immidiately. It was not suppossed to be an auto flower strain. However, it was supposed to be a super early flower strain. Other strains that were started the same way and put out at about the same time veged for a couple months before going into flower.

Do you think that the one hour difference is what caused this one strain to flower immidiaty?

What schedule do you start growing your plants under before putting them outside?

Thank You !
It probably wasn't just the one hour difference.
Anytime you give a cannabis plant more than 6 hours of darkness in veg, you are setting it up for flowering. Darkness releases hormones that are a 'gateway' to flowering.
As long as the plant gets less than 6 hours of dark, it shouldn't release these hormones, so it shouldn't go into flower unexpectedly (unless it's an autoflower strain, and then it would be expected anyway).
By giving your plants 8/16, you were essentially teasing them into flower at the first sign of change.
