After the work and study it took for my first topic, The Ebner Effect on Cannabis seed I became interested in the electromagnetic interaction plants have with the air, soil, Sun and Moon.
What particularly interested me was the effect ParaMagnetic(attracts matter) Rock has on plant growth.
Otherwise known as lava sand, PMR doesn’t have any mineral value in and of itself, it does however increase the energy flow through the soil enabling plants to have greater access to diametric(does not attract) matter.

I do not yet have the resources to do a side by test as I really am intent on the continued development of my living soil recipe.
I won’t share much on that yet as I still think it needs a few more grows to prove it out.
One thing I have found is with PMR and other rock dusts, recycling your soil becomes an actual refining process as the soil becomes better with each grow.
