nice..i did one a couple years ago with a sliding glass door over a about a 3 ft x 6 ft hole 3 ft deep..on sunny days the temp will be high but on cold nights and after a few cold cloudy days in a row the temps will be cold..not as cold as outside but too cold for like tomatos..it was cool to see the snow melt from around the edge tho..some type of added heat source is needed..hope u have better luck

@CheapEnergyIdeas If the earth itself is insulated around a

hotbed for a foot or two, it gets warmer from the earth beneath

it, it's just like being deeper in the ground. Also, if you use

an insulated cover over the bed before and after the majority of

the daytime sun exposure, it will remain warmer all night, which

keeps your plants from going dormant. Being deeper in the ground

and adding decaying material as a mulch blanket helps, as it both

contributes heat and insulates.

@ergenicplayer I will say overall it has been a warm winter so far. But we have a few nights that were in the teens and a few days that only reached the 30s. Thanks for the question, Lonny
