HOW IT WORKS: GRO-MAT is pre-tested. The thermostat is set to the correct germination temperatures. The mat and rack work together: heat travels upward through the open space between the flat and the mat. Heat circulates into and through the soil.
TEMPERATURE: GRO-MAT's electric heating element produces and maintains a uniform radiant heat. This heated rubber mat is thermostatically controlled: the heating mat is maintained at a constant temperature. The heating element is molded within the rubber mat to eliminate danger of fire or electrical shock.
PLACEMENT: Use GRO-MAT in an area not affected by another heat source. Avoid placement near a washer, dryer, television or heater. Keep the mat out of sunlight that comes in through windows. Light helps seedlings from getting too leggy but be careful of the heat effect.
Carefully locate mats to avoid damage to underlying surfaces. The heated rubber mat can discolor or crack some delicate surfaces susceptible to effects of heat. Use cardboard or similar insulating materials under mats placed on surfaces that may or may not be heat sensitive.
MOISTURE: In the beginning of seed germination, keep soil moist and watch flats closely. Added heat causes soil to dry out faster.
INSTRUCTIONS FOR HEATED PLANT MAT:
Plug GRO-MAT into outlet.
Place seed flats directly on wire cage.
For very small containers, place a wire screen or wood slats over the cage.
Water seeds with lukewarm water. (Cold water can kill or stunt seed growth.)
In extreme cold, cover flat loosely with plastic. Make sure there is air between the soil and the cover. Moisture forming on the inside of the plastic is a sign of poor ventilation: raise plastic if necessary.
After plants begin to grow, start new seeds by placing new flats closest to the heated mat. Stack the already-started flats on top.
Remove plants from heat 3-5 days before transplanting. This helps harden the plants to adjust to the cold.
Enjoy your colorful garden, delicious vegetables and heirloom plants.
