The liquid is very convenient to just pour out on the ground, I was going to try cooking up a batch by boiling some chunks of mineral blocks, but does anyone have any knowledge in this area?

I have used that stuff,I think I got it at wall mart,you might be able to get the ingredients off the lable thats on the jug and get an idea of what its made from,hope this helps,by the way I think its only 6 bucks a jug,it may cost more to make it than it does to buy it,good luck
