when its time to chop down

I'm just wondering when it time to cut the plants down should you wait until the lights come on or do it before or does it matter.

It doesnt really matter. You are going to cut them down anyways. But if you need the light to see what you are doing, cut them with it on, lol.

light degrades thc. alot of people will keep it in the dark 1-3 days b4 harvest to make it push all its remaining energy into the buds and draws out resin.
