She looks really nice and fat.
She's definitely in the harvest with window. As you said you like a more C high.. so yup harvest.
You have some different drying options.
The best I've done. Was soft flushing my synthetic nutrients out I did a few tests. And I can say drying the plant in the soil (leaving it on a low ppfd) and your plant will start to dry out. Then pull from the roots and bag the roots if you can clear the sub. (Do not wash off) This was my best tasting weed.
Or you can harvest whole and water an hr before harvesting. And then if you want you can dark rest for 48hr but make sure there's no light hitting it as it'll dry out the soil. Pull out at night or chop from the stem and leave trim on. After a few days before the leafs curl into the bud I usually take them off and. These are the best tasting plants I've harvested..chopping it from the stem is very stressful. (But if you not dark rest and just chop. Be sure she has 2 hrs of dark to stop photochrome (this is when your plant sleeps. So it's less stressful. That's why ppl dark rest and also it is said to enhance resin glands.
Enjoy your harvest.
