A certain 0° wouldn't phase me in the least. The freezing point of tobacco is below - 3°C. But if it reaches that, it's screwed. It would be better to harvest early via stalk harvesting, and try to cure it.
Well, what I said about light period works both ways for tobacco. Lack of photo period response.Although this is my first season growing tobacco, I'm trying to do the opposite. I want the plant to spend it's energy making leaves, not flowers.
Shortening the light cycle of photoperiodic plants will cause them to go from their vegetative growth phase (where they spend all their energy producing strong stems and leaves), to the flowering phase that's all.
I was incorrect. It wasn't Don. It was @Ben Brand .Ethrel. Don used it once and was happy with the results.
Ethrel
Ethrel is a growth regulator used in major horticultural crops and cereals. It promotes ripening in tomatoes, reduces curing time and promotes colour development in flue-cured tobacco, accelerates fruit maturity in apples and blueberries and loosens mature fruit from the stem in cherries for...www.cropscience.bayer.ca
This spring i'm growing 2 strains, prilep and ahus. I started all seedlings in the same cabinet under an LED growlight, with 16 hrs light and 8 hrs darkness. The Ahus began putting on blooms a few weeks after transplant and only 4 to 6 leaves formed. The prilep has shown no signs of blooming and is growing rapidly. So I would say the ahus is a photoperiod type and prilep is not. All plants are being grown exactly the same way, so it must be that going from 16 hours of light per day to about 12 hours a day triggered the ahus to flower. Will not be growing the ahus again.This question (and answer) has come up before. I'm going from memory rather than looking up a reference, but I recall that only a small number of tobacco strains have been shown to flower based on length of night. White mammoth being one of them, i think.
