Scent, that would be a good idea. BW likes very warm soil and will take off quickly once the soil temps reach 75+ degrees. Nothing wrong with what tooln did, and I think it is a great test, but the risk of slower than normal growth and the risk of losing the whole thing to a late frost is very real in that situation. I honestly don't want to see tooln's plot get frosted out, but it would be interesting to see, if it did get down to about 26 degrees or so, how much frost tolerance it really does have in the early vegetative growth stages, as we all know that frost will smoke the mature plants later in the season. I have a theory that the young growing plants might just be able to survive a bit lower temps than the mature plants that have used up their energy producing seed.
