We have found that this custom medium works great when potting Orchids! We learned this from trial and error over the years trying different commercial mixes. Your orchid will love our handmade medium! The charcoal helps combat fungus growth. The clay pellets and coconut husks retain moisture while the perlite aids in drainage. Add it all up and you have the ultimate Orchid medium! Try it...your Orchids will love it too.
