The Pro Grow Heat Mat is a tried and tested essential for any indoor plant growers. It warms the root zone by 5-10 degreees Celsius, so if the ambient room temperature is 12 degrees, the roots would be up to 22 degrees. The warmth provides a bit of extra oomph which helps with seed germination and plant growth - especially during those cold winters!
Works perfectly for growing microgreens in our microgreen max trays.
