Hey guys
I grow my VFTs indoors under growlights and now that dormancy season is coming up, I want to see if its possible for me to reduce the photoperiod to local sunrise - sunset (10 hrs where I live) without altering the temperature too much. I heard the main drive of dormancy is reduced photoperiods but I haven't read anything about keeping the temperatures so I wanted to double check.
thanks in advance!

I have heard the same thing, photoperiod. All of mine are indoors. It doesn't get as cold in east NC as some people think.

IMHO cold temps are necessary. Think of where they come from. But good luck with that.

I lived there though. It didn't get cold like you think. Infact, I never wore a winter jacket. I think at most it was a hat and hoody.... hoodey? Hoodie....

I have roughly the same question cuz I lived in Columbus county NC aka the green swamp and like Cross said its a temperate area near a coastal region. So during winter it warms to 50F days and roughly freezing at night. At least that’s wat I remember. I’m basically doing the same thing with my lights since my basement stays around 50F
and for the fact of the matter I wore a coat lol.

For dormancy there does need to be a temperature drop and reduced photo period. The amount of a drop is what is in question. Freezing temperatures are not required but a period of lower temperatures, perhaps under 60, are needed to start the dormancy. As has been reported other places, dormancy is not "require" but skipping it requires special conditions and practices. It also seems to be dependent on the cultivar. Some do better than others. Refrigerator dormancy is required for those places where the temperatures never get below 70.

That would be cold enough. Typical indoor temperatures are higher than that and are not suitable for inducing dormancy.
