Our Ultra Paramagnetic Andesite Rock Dust has one of the highest centimeter grams-seconds readings we've ever seen. Calculated to be 7000-10090cgs this high quality rock will encourage water retention, worm/ microbial life and resistance to predators and environmental factors which results in higher yields
Ultra fine products cannot be used to raise paramagnetic properties in a significant way and are typically around 1500cgs from our testing. This product is by far the best option for raising your paramagnetism without causing heavy metal contamination or excessive iron. Andesite is a grey to black volcanic rock with between about 52 and 63 weight percent silica (SiO2).
We no longer sell the ultra fine basalt due to unnecessary transportation. You can source this product yourself at your local basalt quarry for next to nothing, we recommend the crusher dust grade for most purposes.
