Sasquatch Posted February 2, 2021 Share Posted February 2, 2021 What's in it? Surely it would take forever to break down like so many other of these mineral additives ? Just anther flash in the pan like the rock dust hype last year. Link to comment Share on other sites More sharing options...

Sasquatch Posted February 2, 2021 Share Posted February 2, 2021 OK so it improves drainage, whoopdeedoo. Plenty of other more easily available and cheaper drainage improvers around. 1 Link to comment Share on other sites More sharing options...
FarmerPalmersNT Posted February 2, 2021 Share Posted February 2, 2021 It provides a porous sponge like structure. That allows for colonisation by bacteria/fungi/microbiota across a gradient of conditions. So if your bed dries out or fluctuates environmentally your bed is seeded with bacterial refuges for recolonisation/recovery. And yes, also improves drainage, among other things. It's expensive but it retains its integrity for longer and is better than many of the alternatives. 5 Link to comment Share on other sites More sharing options...

FarmerPalmersNT Posted February 2, 2021 Share Posted February 2, 2021 That 24 minutes ago, ratdog said: https://hesspumice.com/pumice-pages/pumice-uses/horticultural-pumice.html Refers to pathogenic microbes. It won't 'host' them as a substrate in its own right, as its inert. Hence its suitable a sterile media. That's useful consumer info for purchasers. Once it's in soil soaked in nutrients, organic matter, water it absolutely will, without any doubt, host multiple micro organisms and biota. Therefore acting in the way I have described. 4 Link to comment Share on other sites More sharing options...
FarmerPalmersNT Posted February 2, 2021 Share Posted February 2, 2021 In fact this is precisely why it is such an excellent biological filter media for a variety of purposes, industrial and in aquarium filters for example. It is exceptionally good in this particular regard. Rapid and sustained colonisation. 5 Link to comment Share on other sites More sharing options...
modeflip Posted February 2, 2021 Author Share Posted February 2, 2021 It’s also more sustainable than perlite. 1 Link to comment Share on other sites More sharing options...
