What is the Temperature of a Gro-Mat?
Q: "What is the factory preset temperature for the Gro-Mat built in thermostats for the SUPER Gro-Mat Mat Size 17 X 37 with Frame ? Thanks. Harrison.
Answer: 130 to 135 degrees F. This is considered the optimum germination temperature range. The mat and rack work together: heat travels upward through the 2 inch open space between the flat and the mat. Heat circulates into and through the soil.
Sincerely, Barbara
