Finding Hydrostone

[Discus]

I'm not aware of "hydrostone" but "hydroton" is certainly still manufactured. PrimeAgra varies depending on the batch; some appears to be better than hydroton, some not.

Hydrostone is a US manufactured, fired clay product, but not a lightweight expanded clay pellet like Hydroton or PrimeAgra.

May I ask where you get the information that PrimeAgra is variable in quality? I am the sole distributor of it, and ever since the original factory was closed, and the new one began production - about 8 years ago - it has been extremely consistent.

Ray,
until you responded, all the previous people posting were outside the US. I don't doubt you at all.
