    I live in the midwest and I have 4 plants going outdoors in 6 gallon pots. The biggest is nearing 4 feet tall now. According to the farmers almanac my area gets its first frost in early september. The plant will not even be flowering for a month before this happens. The plants are in the woods where I wont be able to tend to them on a daily basis so im wondering CAN large healthy marijuana plants handle light frost if its brought on gradually as part of their enviroment? Is it worth it to risk it, well theres no other choice i cant put a 6 foot plant in my house :/

    Opinions please thanks

    frost will affect the leaves but not the buds. if the stems freeze, the plant dies. it usually has to drop below 30 at night to kill a plant, so quick snap frosts are not a big deal so long as it takes a while to get that cold, and warms up quickly.

    Yeah it will still be in the mid 50s during the days it just may reach frost point briefly on some nights but it still always gets above 50 during the days. Thats more what i was asking also will those brief frosts kill it. I guess ill just let it go and check it after any possible frosts. I'd imagine a hearty plant could adapt over many months to the cold coming. Also they are all indica/sativa hybrids if that matters at all. Just some bagseed

    almost every strain in existence is a hybrid. true land race plants are impossible to find unless you're in the know.

    indica dominants do much better with acclimation to cold temperatures, and some are very cold hard and frost resistant. acclimation is the key, and on nights where it may drop into the 20's, bring the plant/s inside if you can. simple frost bite will only effect some fan leaves, and will leave bud leaves and flowers to mature. a full freeze through will kill the plant, but not a snap frost.

    Well the plants will need to be out till late october to complete but temps at night could drop into the 20s by then. But if they can survive through september I should be able to have somewhat of a harvest, a couple weeks premature though :(

    you should be good as long as it doesn't freeze like someone mentioned.. the frost will actually cause the plant to make more resin to protect herself.. up until it can't survive any longer.

    Another question I ordering grow big off ebay and the shitty ass people sent me grow big hydro the stuff in the blue bottle. Which is 3-2-6 not 6-4-4 pretty pissed left bad feedback and they refunded me totally so it cost me nothing at least. But is this stuff effective for soil plants? Ive been using it and it seems to work plants are lush green.

    Hope you dont mind If i chime in on this frost thread and ask another question for I am curious myself. And Im trying to save that electronic Paperbongsmilie Anyone know what the temp needs to be for trichomes to be affected and lose the potency of the plant. I figured a plant can survive much colder temps but at some point your gonna have trichomes burst from cold temps correct?:bigjoint:

    Its my understanding when it gets cold it makes the plant throw out res like nuts. I would guess anything below 45 degrees would be very cold for a plant of tropical origin. I doubt anyone will be able to give a textbook answer to that. I'd imagine temps not quite freezing such as mid 30s would cause some intense budding! I can't wait till it happens. I'm going to make a thread all about it in here when it comes september because I think it would be a good little study showing pics of the plant and daily/nightly temps and effects of frost and whatnot :)

    Sorry long as paragraph I just smoked a joint im in the zone

    resin is genetic, and the result of your ability to provide proper conditions. correctly grown happy pot plants will produce the most copious amounts of resin. cold will have no effect on the chemicals within the trichomes. cold temps slow production a bit. ideal temperatures are 75-85 for flower.

    just saying ;)

    your hydro nutes should work fine for soil. i don't use fox farm, it's more formulated for tomatoes, imo. i like gh and an (or any comparable three part formula) plus cal/mag and a flower booster.

    Hey thanks for that answer about the hydro nutes for soil I had the same question

    But also I'm disappointed that the cold won't spur resin production

    Resin quality and profile is genetic.. but the amount of resin produced is no where near genetic.. the resin is a protecting/defense device.. there is a purpose.. not just to get you high man...

    and why do you think there's studies on UVB lights really bringing out the resin on a plant.. because it's protecting it..

    In canada... I was told by an older buddy of mine that showed me the ropes.. he grew outdoor for 15+ years.. and he said if you can leave it for the first frost.. do it.. it will put on some weight for you..

    I'm interested in seeing what happens to mine. I germed 5 seeds today and will put them outside when they're big enough, 2 OG Kush, 2 White Widow, and 1 Arjans Haze #2. First frost is supposed to be Nov. 7th, the winters have been rather mild lately though. I'm not expecting them to get too big, I'm just experimenting. Hopefully they will be big enough to yield at least 3 oz's between the 5 of them. If they do it will go great with the other 7 I'm growing outside.
