Again, just my experience here in the South, but I would say that 30-40%
humidity for Sarrs. is very low. Here in Tampa, at the southern fringes of
Sarr. country - with breezes off the ocean- 60-70% humidity is low for any time
of the year. The southern US where Sarrs. grow has high humidity all year
round (80+ easy). High heat with low humidity I would say is very risky.
