yeah, I may end up calling it at 10 weeks this time as I want to wrap up and get things shut-down and incognito/hidden so I can have contractors in the house. That may derail the experiment but 8 weeks has passed, they look nice and fat but haven't checked for any amber yet or any of that jazz.
Probably let them set for at least a few more water-only cycles a few days apart and then start the harvesting process.
Would be interesting to see controlled scientific studies that looked into this - the commercial grows aren't interested enough to be funding that research though.
