This year we have decided to try make our own potting mix as the most easily available one
is not all that good and contains peat. Despite the distance coconut coir travels, it is a
much more sustainable resource than peat and we are very excited to try it as a growing medium.
Bat guano will be used as a nutrient source as well as trying some mycorrhizal fungi that I actually
first heard about via a TED talk on phosphorous depletion.
The above perlite and worm poop is a purchase from ebay, and will be included in our potting soil.
