Lol. Harvest window does not decide effects of the strain. Genetics do. Harvesting early doesn’t give you a sativa like high or racy high. And harvesting later does not give you an indica type cochlock high There only one way to harvest cannabis. On time
Actually harvest time totally changes the effects. But I'm not suggesting to intentionally chop early though. If you want a more sativa high, grow a sativa strain, and if you want an indica, grow an indica.
I've grown a Sunset Sherbert a bunch of times and harvested a bunch soon when I'd see nanners. Even though it's an indica, it smokes like a really mild sativa when you chop it early. I've done 28 day, 35 days, and some other early ones that I forget how long I let them roll. I did make it the full 70+ days a few times though. Still have a box of that strain.
Anyways, the early shit is my wife's favorite. She loved the 28 day stuff, and is now on the ~35 day stuff. She just had me fill her little jar today so I grabbed a pic too for fun when I was filling it.
Full disclosure: I do not support chopping early, lol.
