Ken Bar Agritabe Seed Tray Heater.
9" X 2 FT heat mat. Provides 85 degree heat for seed germination or rooting.The Ken Bar heater is a very good product to start cuttings because it can deliver the needed heat that most other bottom heating mats can’t. The mat can deliver 85 degrees to the bottom of your tray. That’s good because often times the cool days and nights can rob heating mats of the necessary heat needed to transfer all the way through the mat to the growing media. Remember that the growing media (not air and not tray) temperature should be between 72 and 76 degrees. The mat gets its power from a 24-volt transformer. That’s good because its low voltage. I get a little concerned about heating mats that are powered by 120 volts. These mats are always around water. High voltage, people and water are not a good combination. I’ve seen some 120-volt mats with no ground wire on their plug. How smart is that? This is a good safe mat heater. PS If you need more heat place insulting material under the mat. If you need less heat, place spacers under the tray to lift it up from the mat.
