Help with when is the right time to chop

Hey! Harvest window opens when you start getting amber pistils(hairs). The best way to check is looking at the trichomes. Clear trichomes haven't reached their full potency, cloudy ones are full of THC and amber are losing THC while gaining CBN. So depending on your preference whether you want more of a head high or body high. I normally start to look at trichomes when there are about 50/50% white and amber pistils. I harvest when after examining and finding 70% cloudy trichomes and 30% amber trichomes. For me that's a prefect combination, depending on the strain as well. With some strains I go with lower amount of amber trichomes but always attest 10%. As for what they look like, clear trichomes look like glass, cloudy like plastic and amber like resin. To look at the trichomes you need at least a 60X jewelers loupe, you can find it for 5-7€ anywhere.. Good luck and happy Growing!
