Just a reminder to calibrate your soil thermometer if you haven't. Test it against a known thermometer, and then adjust if it doesn't match, before you rely on it.
Yes, but you still need to calibrate it. They have an adjustment screw.Gilley11 said:Are there actually thermometer sold as soil thermometers? Couldn't you just use a normal bbq thermometer?

I think the soil ones are just a bit more durable,. I haven't bought one yet, but I damaged my regular one slightly pushing it into the ground. It still works; just a bit bent and the scale has some cracks.
I check the calibration by placing it on top of a thermostat for a few minutes.
It's digital and wall-mounted, so I expect it to have been pre-calibrated. I don't know if it can be user-calibrated. You're making me wonder though. I could always check it against another digital thermometer.Gibby said:What do you calibrate your thermostat with?Green said:Yes, but you still need to calibrate it.

I'll look into it, thanks. How did you do it? What did you check against?Gibby said:@Green mine are digital too and I had to calibrate them, 1 was 1.5 degrees off and the other was 2.5.

Outside of the device measurement error, your test method will have more error (eg. 3.5in of soil depth vs. 4in, time of day,). I think going by the greencast soil temp is more than good enough.
