Not much use in providing enough bottom heat for plant rooting or germination. The cables I use are can be used for both pipes OR imbedded into potting medium and are thermostatically controlled to turn off at around 75o.

Rhizo, you got mail.

Gardenfreak, apparently the Gardenweb email system doesn't work most of the time. I didn't receive any email.

Just copy the address and send me a message directly.

Just wanted to know what the cable is called and where you purchased it.
thanks

Don't remember where I got it, or the brand name but this is exactly what it looks like. I use cables to heat the soil INSIDE my plastic germination flats.

I'm almost certain that I bought the cables off the rack somewhere, probably over 10 years ago. You can find them on-line or in gardening catalogs now.
