Our mix keeps it light and airy for easy planting, with a healthy dose of chunkiness for optimum drainage and aeration.

We also give you the option to add pumice to the mix. Pumice further enhances the structure and drainage of the mix, but we know not everyone likes the look of light-colored materials. It’s your project, so we thought we’d let you decide!

Orchid bark (and optional pumice) creates an airy, well-draining environment. Supporting a healthy water cycle and letting your roots breathe freely.

Moisture retentive

Our coco coir base supports those all-important humid, tropical conditions without weighing down your plants’ roots.


Horticultural charcoal forms the bioactive backbone of your self-sustaining terrarium, providing a natural platform for beneficial microbes, fungi, and bugs to thrive.
