the hair colors should be a genetic trait. do you mean should the trichromes turn amber? then yes. you should harvest when you have ~75-80% amber trichromes.

once again, flower time is plant specific. is it gettting at least 12 hours of uninterrupted darkness?

headshake Reviewed by headshake on . Another noob question on harvesting first thanks to everyone ive read many threads and its been very helpful. but here comes the noob question. when a plant is flowering and its getting ready to harvest will all the white hairs end up turning brown? and is it comon for plants to take longer than 90 days to flower and if they are how would u speed it up?
