are you in californiaI ve been growing indica strains all round year from last year....those plants been in 60's in the day, i ve always move em in the house every night to prevent frost...they were perfect fine with beautiful purple pistills
I have two clones that been flowering about halfway to five weeks now...4 or 5 weeks more to go...average in my area is 50's in the night time and 70's during day....the pistills are still white, no color or purple anything like that yet...this time I will leave em outside at night time to see the end result. I should expect the frost by end of this month...it will be 27temp in the night time....Ill let ya know how those clones fare , next month !
keep share the exprience, growers

i am under the impression that if you keep a plant under a 24 hour light cycle until it is 4 or 5 feet tall and then stick it in the ground outside it will finish cen cals longest day of year is less than 14 hours of light ???

I don't even take a chance with frosts. Even though I started my latest grow outdoors in January in the northern hemisphere, I at least have the sense to keep my girls in buckets so I can move them into my water heater shed with a space heater during freezes. Fortunately it doesn't freeze here often and the daytime highs are already near 80℉. The lows at night are just above freezing, but I still take them in because I've awoke to 35℉ with frost several mornings already.
Oh, and I think it's damn funny there is a report option on my own replies.

Lots of strains of cannabis can handle a pretty strong frost. I've had plants handle frosts as low as 28 degrees F without killing the plant.
Things to consider, some strains are more sensitive to frost than others, if they are in pots this can make them more sensitive.
Sativa strains tend to be more sensitive to frost than Indicas. Indicas and Indica dominant hybrids are capable of handling frosts as low as 28F. but there have been reports of sativas handling frosts just as well.
I'll leave this sticky open to discussion for other experienced users to post their experiences, I will compile it into this. I felt this was needed as this question gets asked a lot when a frost comes by.
you can protect the plants if they are of manageable size or if you are handy enough to build a sturdy setup.
this can be as basic as a pvc greenhouse with plastic wrapped around, or even sheets if properly secured to not touch the plants... or as large as a full car port with greenhouse grade plastic secured.
how much the temperature rises the next day also tends to define how the plant deals with the frost. if it frosts and it rises up to 65 degrees+ with sun in the daytime, the plant is much more likely to take the frost and keep growing vs a plant that takes a hard frost and sees a 45 degree day with clouds....
cooler temperatures (55-40 degrees F) will definitely bring out some purpling in some strains, and cause flowering to speed up, nights that dip into the 35F zone boost this even more, bringing out even more color.
sorry for the organization of this thread, guess I'm too much of a stoner after all

Good morning,
Yes cannabis can handle some frost but I must warn you all (I live on the prairies in Canada) it does affect potency and any buds damaged by frost (frost bite per say) is no longer smokable. You will have to make oil. Another thing nite after nite of temps cooler than 45-50 degrees slows down maturation. Several nites of frost or near frost cuts potency I'd say up to 75%. I had plants inside and out and the difference made me wish I had a greenhouse. So I bought some plans online and built my own microclimate (and it keeps pests out). A small electric ceramic heater and I can grow until the end of September to mid October, the plants are great. here's a pic. C99's 60/40 Sat/Ind.
If anyone is interested I have some tips on storing solar energy (heat sinks) to be used at nite to help heat the greenhouse.

Sorry my experience growing above the 50th parallel doesn't jive with your experience growing below the 40th. I'm assuming you live in the south because of the time stamps on the photos. Jan 2 and Dec 19th
Nite after nite of 32 degree temps and daytime highs of 45-50 saps the life out of the plant. One or two frosty nites in the southern states is not as critical because of daytime highs are probably in the 60s or 70's. In late December you're only getting 9 hrs of sunlight why are you waiting so long?

anyone prefer to use autos outdoors to avoid the short growing seasons? or just let it go the longer route and run the risk of early season front and last season wet season?
