For me, the best time to germinate is when I need to start the next crop.

Altho I'm sure the practice came in handy back before banks started giving calendars to farmers, I am doubtful when it comes to relying on farming folklore to grow cannabis. Especially indoors where we control every aspect of growth, and (for the most part) have no worries about a coming frost.

Curious...have you ever done a side-by-side comparison of results?
