Anyone know of a HBS or pet/farm supply store in E/SE melb that sells rice hulls (if pet/farm store then pesticide free!)? I know G&G have them, but I'd have to get them posted (reserved as a last resort). As for substitutes - I've got a stack of pea straw for the strawberries at home. Would that work if it was chopped/blended up (and rinsed)? There was mention of wheat bran (as in cereal) from a UK forum, but I'm willing to bet this might just be a silly pommy idea.
