Soil temperature.

[Worth1]

I have been reading my soil temperature in the same spot for several days now.
While doing this I have been observing the growth of the plants.
They were doing so so at around 62F until it came a cold rain the other day.
This rain cooled the soil down a wee bit and the growth slowed down.
Today I noticed over night the tomatoes started taking off and I took another reading.
The soil temp today is 68F
Now my thermometer may be reading 3 degrees on the hot side and there is no way to calibrate it.
I cant find my good ones so I am using my electronic meat thermometer.

There are also two Black Prince tomatoes that are dark green that aren't growing like the others.
But today they are just starting to show some better growth.
The tomatoes that seem to show the best ability to take up nutrients in the cooler soil are San Marzano.

Just thought I would do this so folks could get a better idea of how the plants will do in differing temps.

One last note, I have been testing the roots also and from the time I put the plants out they have been growing.
The soil I think was 55F when I put everything out.

I am guessing that in the next two days if it doesn't rain the soil will be up to 70F or more.

I also have pinto beans starting to break surface.
