how cold can my plants handle it?

How do y'all? Last night got down to 59 degrees in the grow room. I hear in general it should not dip below 60 or else thc becomes less potent.

My room will go down to that and lower during the winter, i do not notice any potency changes

any lower then 55f then its time to get concerned. the leafs will start to dye. or brown or turn red . time to get a small electric heater . should not run that much in a small room. get a good one. and in the long run it will save you electric a digital one would be best. should run you about 100 dollars. or if you have a nice grow you can get a window ac unit that has built in heat triple bang for your buck. can keep it any stable temp all year. and dehumidify. about 300 total

You're only 10F below the optimum low. They won't die until they start to freeze, but they sure won't grow any. A way to get your grow room a bit warmer if at all possible is what I'd recommend.

Theyll be fine. It hit 30 and had freezing rain before i chopped my outdoor shit. probably the only thing that kept it from getting molded. hahaha.

The weather snuck up on me and they only went through about 24 hours of that. But they looked fine the next day and i waited til night to chop and they didnt show any drooping or discoloration besides the usual fade they get from end of flowering.

as long as they are kept warm during the day with the lights on they will be fine
most likely show more coloring reds n purples etc
i have not seen it go below 55f but it will be around 58-55f in my winter months
i haven't noticed any slower growth over the summer months if so i would consider heating
but that really is a last resort as it could work out expensive
outside they will survive very low temps as long as no frost/ frozen roots

peace
