you can harvest now or in a few weeks time, it depends on what your looking for in a high, chop early and you get a somewhat racy high, leave it to fully mature and you get more of a couchlock high. but ppl prefer to wait, get a little cbn on the plant
nutty gives some great advice, as do the others, no bad info on the thread,
you can chop parts as they mature is another way, wait till the top of the plant matures, the top matures faster then the lower part, so multiple harvests from the one plant.
so its down to the growers personel prefrance
