[papercreters] Re: Papercrete as growing medium

Mix
---

You folks have a lot more experience than me with weak papercrete mixes, so what would you suggest? I'll do one with just pulp, and probably 2 with differing amounts of cement. Cost is critical, if cement cost per stick exceeds 30p (1.9kg) then its not doable, and I really want something much cheaper.

The other question is how to treat the papercrete after casting so it doesnt burn plant roots?


thanks
