So based on what im getting here and through research around the interwebz ive come to the conclusion that unless you're using it for a TLO component that you plan to treat as such in the future, it is generally advised against reusing ffof as a straight amended medium. So based on research here im pretty sure im going to stop buying traditional soil and begin preparing a TLO batch that i can continuously use, feed and amend. I want something simple to start with that i can build into and adjust as the mix grows older. I saw your beginners post on TLO's, X. Lots of great info in there. Thanks for taking the time to post that man. The info seems a bit daunting at first but i think im going to enjoy digging into this organic thing =)
