Not a newb but been out of the game for a while.

At what temperature does growth stop on the low end?

Temps in my area (N. Kentucky) are not expected to get above 60F during the day and in the lower 40sF at night for the next couple of weeks (maybe one day in the 60s). No frost warnings have been issued but i have been protecting them anyway.

Is there any point in letting them go any longer or do they quit growing below 60F or so?

Any responses are GREATLY appreciated.

can't remember where i read it but think that cannabis can grow in a reasonably vast range of temps, just means it won't have optimal growth

edit: sorry can't tell you exact temps but look on google for temps and i'm sure there will be something

I've got my girls in a green house so the frost won't settle on them, I live in norther NY where night time temps average 35-40 day time temps get up to about 50-55....I need to get at least 2-3 more weeks out of my plants, will the green house do?

Yes, the greenhouse will work just fine. I really think your plants growth is more affected by lumens per sq. ft. than by temps. Of course the two go together in varying degrees (no pun intended), depending upon where you live. I'm in Flori-duh so i grow straight through every season and have had to cover them with cloth from time to time when a frost comes around late jan. or Feb., but that's it. The rest has been gravy train.

Good luck!

out.

A temperature of above 82 degrees or below 67 degrees will very slightly slow growth, but it is not a serious problem that will stunt your plants. Temperatures below 60 degrees or above 95 degrees will stop growth. There is no damage, but there is no growth. An extremely high temperature in the upper 90s or below 58 degrees that lasts for days can slowly result in death of your plants. The most efficient temps for growth are between 72 to 80 degrees. Plants exist in over 100 degree heat in Afganastan, in low humidity, but they are stunted and short.
Plants can grow and thrive in higher temps if there is decent humidity. Plants can not take many days below 58 degrees, but can be revived.
This is based on my experience, and what I have read.
