Hi, just interested to know roughly how deep most bury their soil heating cables.
I am going to give one a go this season on one plant to see how it goes.
Any information would be greatly appreciated.
Cheers.

I prefer 18inches. I think others do 12" heat rises.

Yeah, I'd go as deep as you can to the sub soil.

Hi Shannon I would've thought 18 inches is too deep to impact temps on the surface? I assume at that depth you can leave them there perminatly and till rifht over them? Thanks

Ive heard we dont want to dig pits anymore, so thats something to think about. I wouldnt use the same exact planting hole each year so leaving them seems like a waste.

This year I used cables in two spots and another without, the plant without cables grew the quickest, I am not using any next year, to much work digging.

Hot air rises. Heat radiates. 6-8" works for me. When I'm too deep the soil won't warm up. I was fairly shallow once and it still worked.

I insulated the surface of my soil to trap the heat. It is always 80°

Cheers, so if i went with 12 inches deep, that should work fairly well.
Will be good to see how they work this season.
