I've noticed that many people use coffee grinds on some of their more acid loving plants. Has anyone tried this with success on their cp's? I roast coffee all day long and have a plethora of beans. However, I think that the grounds might harbor mold. A secondary product of the roasting process is "chaff" this is a thin skin that comes off of the beans when they pop during roasting. These skins flow with the heated air out of the roast chamber and into a collector. I have more than enough for a lifetime of experiments. For twenty years we've been giving this to customers and they keep coming back for more. I intend to grab two baby food jars sterilize them and add grounds to one and chaff to the other, seal them with just a little moisture. Although the grounds would be tainted just by the process of brewing, the chaff on the other hand is in a tornado of 450-500 degree air leaving it pretty clean. Does anyone have any thoughts on this. Would this be a fairly controlled experiment? I plan on using the same batch of beans and chaff i.e. brazilian beans and brazilian chaff from the same roast. I look forward to hearing your thoughts.
