Dormancy seems to describe two phenomena. One is the actual process and the other is like a deep sleep. The process part is what a plant is naturally going through as the photoperiod decreases, beginning in the summer. The temps are still hot and the days are still long. The plant is still growing, but things are changing. This process contimues through the summer and fall, culminating in a deep sleep in the lat fall/winter. The process part and the deep sleep part often get confused. Conversely, in the middle of winter, the photperiod is increasing while the temps are still cold. But it will soon be time for the plant to be waking up.
Your plant typically should be experiening the process of dormancy right now, though it won't be in a deep sleep for another several weeks. It needs a dormancy, just as we need sleep.
People tend to think of dormancy in terms of temperature, disproportionate to photoperiod. but light seems to be more significant, certainly more significant than, relative to temperature - but both are important.
A dormant VFT exhibits little or no growth when dormant. Mine were cold enough so that the 3 traps the were in development when it went into a deep sleep, just stopped developing. When I took it out of the fridge and placed it on a cold window sill to warm up slightly, the traps continued to develop.
My VFT's are outside, experiencing 80 degree temps, but the light has been decreasing since late June. It is still putting out leaves, but it is also "easing" into dormancy.
