I was wondering what month is considered a late harvest, end of october or november? I have a greenhouse so I can cover them with plastic when the rain comes. But I would like to keep the heating to a minimum. I plan to have the greenhouse open unless it rains but how low temps can the buds take with no rain? Do I have to cover with plastic every night towards the middle of October or beginning of November? I heard marijuana can take temps up to about 38? I would like them to be open direct sunlight as much as possible and prefer not put the plastic on unless of a storm or rain. Sometimes I heard Southern oregon gets lucky and doesn't get much rain till december or end of november. I would like alot of amber trichomes because I have bad insomnia. I don't want risk cutting too early and getting too much of a sativa high. I want something to really knock me out sleep mainly but dont mind a trippy mind heavy sedative type either! As long makes me sleep hard I don't care if its mind fucker too!
