Soil Warming Cables

Built-in thermostat automatically activates cables when soil temperature is below 74˚F.

  • Speeds germination and seedling growth, producing large healthy plants, ready for transplanting.
  • Use indoors or out to get a jump start to your growing season.
  • Cables are covered with a tough, moisture-proof PVC jacket.
  • All connections are sealed and waterproof.
  • Available in three lengths. To determine which is best for you, match cable length to square footage of your planter.
  • Team up with our Heavy-Duty Commercial Cold Frame (106363), sold separately, to create your own hotbed.
