ive yet to search online for it but the method is.
take a 55 galon trash can and line it with a trash bag. take a shower curtan made from polyester or sum material that wen u hold it up u can see light threw the tiny holes in between threads. put the shower curtian secured around the lip of the can and add ur cuttings and take wut i think he described as a basic paint stir and stir it against the fabric. and after 10 mins ur left with all the goodness on the other side of the curtain stuck to the trash bag. they say its better because wen making water hash the terpins get washed away so with this method u still have the plants taste.
