lava rock

I used to throw a bucket full of volcanic rocks in a cement mixer with some water and let it spin for about half an hour then tip the water in to a bucket to put on the garden and simply tip more water into the mixer for another batch of mineral rich water.
Now a friend makes and sells it commercially.
