These heating cables speed seedling germination and growth with gentle bottom heat allowing you to get a head start on the growing season. They have a built-in thermostat that automatically activates the heating element if the soil temperature drops below approximately 75° F which is the optimal root zone temperature for most seedlings and starts. If you want to maintain a lower temperature, you can use one of our plug-in thermostats with remote sensors. Cables can heat the soil 10-15° F above the air temperature. All connections are sealed and waterproof. Each heating cable includes installation instructions and helpful tips. 110/120 volt electricity required.

These have worked great for me so far. My seeds are sprouting much quicker and are growing like wild fire!

Not for seed starting

If you are looking for a heating cable you can use in an indoor made seed bed this isn't for you. I installed the cable as directed on a piece of hardware cloth that matched the size of my seed bed. It's a wood box using sand as the substrate. The cable does not provide enough heat to generate warmth for seed trays sitting on the seed bed. Possibly, If I buried each of my seed tray to be on top of the cable it might work but that is not practical. I formerly used incandescent rope lights in the sand which when buried generated a nice heat fore the seed trays sitting on top. This works if the bed is in a nice cool place out of the sun. If external heat gets to the bed, the rope lights get too hot. All that said, get the instructions before you buy and be sure it's only for soil warming where you are actually planting seeds.

ACF Greenhouses: These are made for heating soil not exposed trays. We recommend our plant heating mats for trays.

Excellent quality.

These were just what I was looking for. First thing in the morning I stick my finger in the soil and its slightly warm at the root zone. Helped me get a jump on my tomatoes. Good price and really quick delivery.
