Seed Starting Heat Mat - Small

The most common reason seeds don't sprout indoors is because the soil is to cool. Sow seeds, place tray on heat mat, leave there until 50% of seeds begin to sprout. Then move to 16 hours of light a day until moved outdoors.

  • Seed starting heat mat has a built-in thermostat that maintains soil temperature 15-20 degrees above room temperature.
  • Warm soil leads to more seeds germinating and more quickly.
  • Grows bigger, healthier plants.
  • Mat can support 3 trays  (from 120-180 small blocks), 9” x 19”.

Here is what customers are saying about how soil blocking has changed their seed starting experience.

    Would have given 5 stars, but until I hear back from my nephew, the gift recipient, had to hold back 1 star.
