processing coconut husks
I'm interested in using coconut husks as a medium- I live in rural Costa Rica and am surrounded by them.
I'm looking for advice on processing them. I have some dry, dead husks (I assume they should not be green) with the pits removed. So far my plan is to put them through a wood chipper. Will that grind it up enough? I've never actually seen coconut husks that have been processed as a growing medium, so I don't really know what kind of consistency it should have.
Then I'm thinking maybe it should be sterilized with, say, a 5% bleach soak- they've been lying around for some time, God knows what's living in them.
Then a rinse with clean water? Left to dry out again? Whaddya' think?
