i'm going to see how certain types of peas will
weather these over night cold snaps.

it is a shame i'm so tired from doing things that i
don't really have much time to do good observations and measurements. i
don't even have a proper weather station.

the raised bed they are in is surrounded by some
rocks and slabs of concrete so perhaps those will hold enough heat in.

i've already been surprised by how quickly the peas
did sprout so perhaps they will all be ok.

good thing it was only a sacrificial round of planting
which i had no idea if they'd do ok or not.

If the mass can be increased, it's possible to have an improvement. The
specific heat of concrete is slightly less than most soils, so as far
as material properties it's no magic
