Regarding a Leachate that has a high paramagnetic reading for homade compost tea. I Was informed that Gardenville Vulcanite has high para magnetic reading. Does any one South of I-30 Handle Gardenville Products. If not how can I be assured of a high paramagnetic that any Vulcanite or Lava sand might have. I'm willing to bet very few Garden centers have a meter to check this

That would be correct. Howard and I discussed this very topic and even the manufacturers do not check on a regular basis. We will have to trust the sources for now.

South of I-30:
Green Gardens in Duncanville
Petal Pushers in Cedar Hill
Greenery in Midlothian and Waxahachie

I am sure there is more, ck. the dealer listings on this web site
