Cold temps

Probably. I used to have 8 foot pieces of 1/2" pvc that I would just shove into the ground, forming an arc over my veggies. Add plastic over that and you have a quick, shit greenhouse for a night
 
Soil temps are a big concern here.

The growth rate of the plant is seriously reduced by not just the air temps BUT, by the soil temps that the roots are in.

The key is how fast the soil warms in the sun available to the plants. Warm feet helps them. Just like warm air.

Watch closely and harvest immediately, if the plant shows signs of frost burn.....

Good luck!
 
I still have plants outside in North East Canada, we already had 5-6 nights of extremely heavy frost and temps below freezing didn't see to bother them at all. Over the past few years I never lost any due to the frost. The leaves and buds usually turn purple the colder it gets.
 
My biggest concern with frost would be the subsequent moisture left behind matched with cooler temps not drying it out quickly. Sounds like recipe for bud rot.
 
Ya that was my concern, I just covered all of them and then tarped the plastic cover to be safe they are fine this morning, seemed nice and cozy on the inside of the tent. Temps won’t dip that low until after I harvest next week! Thanks for the help all

I wouldn't leave them covered that will trap moisture and cause bud rot
 
I took the cover off early this am only covered for maybe 7 hours and it’s a little greenhouse so there was enough ambient air I’m not choking them out, there was gaps for air
