buy it off GE :D otherwise stick fruit harvested from crops that require 50+ farming to grow into the bin 15 fruit per bin. Stick it in, close the lid, and in ~1 hour come back with 15 buckets to empty the super compost you find inside. I find it convenient to buy the 80 pineapples from arhein @ catherby (talk to him, don't trade) and use those you can also use the compost mound and its special ability Dang, screw that, lol, I'm buying it. Thanks though!
