Thanks a million for all the input!
@Dyllian I am very interested in the mushroom thing. I certainly have all the "tools". From what I understand, trees and woody shrubs like a more fungal soil. I am working on a largish bank of black currants with the thought of selling jam at the farmer's market. It would be a novelty here and I think I could make decent money at it. So, right now I am planting my currant starts in little row / mounds covered with cardboard boxes that are inoculated with mushrooms. I didn't really try to be picky... I just throw all my mushrooms between the flattened boxes. Not sure if its a good idea or bad.
@Michael Thanks for the links. I had seen this guy before, but not these particular videos. I have some experience with low-oxygen burns. I actually like the simplicity of the "kontiki" setup... and there was some guy that made a similar setup (if less efficient) with a 55 gallon drum laid on its side and a "scallop" cut out of it. That is what I am going to try with some of my coffee grounds. We'll see how it goes:
