I am doubtful when it comes to relying on farming folklore to grow cannabis.
I agree with the moon phases, effecting all growing plants. My Dad said " plant seeds, by the dark of the moon"...so, I do.

He grew hemp during World War II. They planted it along the fence row, about 6-10 feet out, that way it didn't affect normal crops, like corn, etc. They said it was taller than the corn and twice as thick; as far as the eye could see.

I'm sure farmers over the past 200 years; noticed a trend, about what works best.
