It can be true..with going too long but it was said to be 9 week strain and I kept it 10 weeks to be shure...and its said its rare to over due then under do them...I was using my mini microscope (what is crap by the way,,I am going to get my self one much more suitable one)..like daily trying to make sense of the ripening state...but there is always so many buds in different plants in different stage..AND NO I AM NOT GOING TO START CHOPPING A PART NOW AND PART LATER...when I chop I take all down so I can dry them in that room in dark+ I have space to work with them..
Definetly good idea to take a sample soon as the window opens, a few runs you'll find the " sweet" spot.
If its sticky, swollen, and lowest buds are mature enough, i chop now.
(51-53 days)
I also back them way off the light ( 3 ft from vert 600) when they are swellling.
This is seed grow? If it was a clone of a known donor than there is some tweaking that needs to be done to bring those notes out.
Seeds on the other hand, (that doesnt include you're 3-5 hit and kind of quit hydbrid that tastes and smells good and not much else) can be a little more work to find your Winner.
