Setting fence posts in 30ish degree weather. Using red fast setting bags and my post holes are below the frost line.

Am I going to have any issues with the concrete curing at this temp?

I’m basically pouring a little water in the hole, dump the bag in and pour the rest of the where on top. Then I’ll use a long metal rod to mix it up a bit and let the water soak in.

Once if start to garden up a bit ill fill the top in with dirt.

My post holes are about 30 inches deep and like 12 to 13 inches wide. Using a bag and a half for each post
