how cold is too cold???

out here in the midwest my baby has maybe a month left of flowering im not sure but all summer its been ideal temperatures but this week it has gotten cold in the 70s during the day and around 45 - 50 degrees at night it is spos to be 60 degrees on saturday but then warm back up to 80

i am just wondering how cold is too cold and should i be worrying?

i wouldnt start to worry about a frost till ur gettin into like the low 40s mid 30's at night,its been 40-45 at nights sometimes where i live in new england,but my plant still going strong bout 3 or 4 weeks left of flowering!

Normally the rule of thumb is harvest before or close to the first frost, when you start to see frost in the morning then you should be worried about your babies, but as long as it heats up in the day to a good temp you should be ok.

all depends on strain.some are more hardier than others.some can take a frost some can't.
