It is sitting in heli soil I had from Amazon which is 70% cocopeat 20% rice husks and 10% coco husk shell charcoal. I believe the husks act similar to perlite to help drainage.
It sits on a south facing windowsill, unsure of exact humidity. I have it sitting in around 1cm of deionised water.
Temps are usually around 20c at the moment dropping to around 15c at night.
I will take a pic to upload tomorrow
