Thanks Mikell and ahemait
Rice hulls are easy to source at any brew store … organic is proving difficult. Gaia Green is a great company and their glacial rock dust is quite easy to find. They used to sell basalt dust, but seem to be out of it at the moment. Their glacial rock dust has different qualities to basalt rock dust … in particular the paramagnetic characteristics and also the possibility of higher contaminants - just from the way it is sourced … each batch will be a bit different. Not a huge problem in outside gardening, but in a no-till setup, I would feel more comfortable getting basalt dust.
