Holla all, recently took the plunge on a Thai Constellation and a few Alocasia Bagindas so I've decided to DIY my own potting mix. Which is as follows
2 litres Perlite/Vermiculite 1:1 mix
4 litres Coco Coir
5 litres Orchid potting mix
Do I need to up or down dosages of any components or is she all good?
TIA for any advice, scolding etc

that’s a lot of coco coir. i’d add another part of a chunkier grit like large orchid bark or size three perlite for instance
More chunk! Add perlite, pumice or chunky orchid bark. You can hand-sift the premade orchid mix you already have for bark, if you want.
I started using a coco husk product called “Chips-n-fiber” by Prococo in lieu of coco coir in my aroid mixes. I love it so much. I’ve never been happy with coco coir as it compresses and gets weirdly distributed in my potting mix .
My mix comprises of the chips-n-fiber, horticultural charcoal, chunky perlite, orchid bark and sometimes leca.
Add more perlite, pumice, sand for air to get to the roots. The vermiculite, coco coir and orchid bark all hold moisture.
Update: Mix is now
5 litres Perlite.
4 litres Coco.
2 litres Vermiculite.
7 litres Orchid Bark mix.
