Humid Vivarium Substrate Mix | DIY Substrate Recipe

Here's the recipe for the Vivarium substrate mix I've been using for a year and a half or so now in my dart frog and arboreal gecko enclosures. Several clients are now using it as well with great results for plant growth.
1 part coco fiber
2 parts top soil
1-2 parts tree fern fiber
2 parts orchid bark (can also use reptile bark, but it's just overpriced orchid bark)
1 part crushed charcoal
1 part chopped spagnum moss (can use milled as well)
If you prefer to just order finished substrate, message me through my page / engagingecosystems and I'll get some headed your way!
