Low temperatures at night are OK down to about 60 degrees, then start to effect the growth in a big way. Mid 50s will cause mild shock and 40s will kill your plants with repeated exposure. *strain dependent -Nice avatar jmoney..those are 2 of my favorite things.
Then they should be ok? On thursday the temps are good and only get better from on out. Thanks I feel the same way.
[quote name='OCDinFL']40s will kill your plants with repeated exposure.quote] have you had a plant die because the temperture was in the 40s at night?
I had a plant germinate and sprout out side in the middle of winter where it would get down into the 30's and she ended up growing to be about 7ft. MJ is a very resiliant plant it show be fine
My plants have been growing for about three weeks in FL at first it was in the 30s every night but I brought them inside but I dont want to keep moving them around, I dont want hermies. So far they look very healthy they're growing consistantly but slowly I can see them growing faster as it gets warmer though.
40F = 4C = May be dead if left more than a few nights, strain dependent. I've done my share of guerilla growing and have lost several plants to cold weather. If possible, throw a tarp over it to contain some heat and humidity. Just one night shouldn't be a problem.
My plants have been outside for about 3 weeks now. The lowest temp. since then has been 28. They temp. still gets around 35 at night. Mine are doing fine. Anything 27F or below will kill them
