Soil Temperature vs. Air Temperature? Help Please!
I'm doing test runs for temperature of my germination station I'm putting together prior to actually germinating seeds. I've read everything here and put together my own plan of action on how to go about testing my go at germination, but one thing I can't seem to find is what the soil temperature should be. Should it be in close range to the air temperature or should it be at a higher or lower temperature than the air around it? Any help on what others have had successful in the past would be great! I'm currently getting soil temps at about 90-100 (which I'm sure is too high for bananas, but believe great for cacti!) with air temps at 85-95. I'm using a digital meat themometer to take the soil temps. I'm now going to try lifting up the soil trays with cooling racks and see how much of a difference this makes with the soil temperature.
Thanks ahead of time!
