Guys, what's the temperature (in °C) that a VFT will undergo dormancy successfully?

Photoperiod matters more. I’m in subtropical Florida, and have barely been below 60 F, and mine are dormant.

I would say the same, since I was a big fan of the short-photoperiod dormancy, except I'm a bit concerned about the photoperiod trick now. A few of mine are putting up flower stalks currently indoors under my growlights (turned on 8am-5pm and room temp at 74*F). Maybe I need to make the lights run 9am-4pm.

Anywhere around 7c is really good. That's a nice, solid, safe dormancy temperature but as stated, photoperiod is more important.

Yeah. My night temperatures this time of year drop into the sixties regularly, fifties occasionally.

Can you check my dormancy post, I'm in Florida (Miami) so I thought you might know. Thanks.

The recommended ideal is 3-10C however I have had mine in an outside bog with a large mass down to minus 15C with a light covering of fern fronds over, and didn't loose any. Occasional freezes aren't detrimental in large mass.
Frequent freeze and thaw cycles, desiccating wind and how wet they are kept, are generally the killers.
Cheers

I'm in southeastern North Carolina. My plants are outside and I assume dormant. But they are still putting out new growth. Almost all my typicals are sending up flower stalks. a few are about to bloom. Tonight it will nearly freeze but be 60f tomorrow. vfts only get 3 to 4 hours of direct sun. Some of my cultivars have stopped or nearly stopped growing while others just keep growing. I'm going to cut the flower stalks off.

This flowering typical has been very aggressive its whole life.
