Two of our own tried and true blends for all your Aroid & Hoya (and lots of other stuff!) potting needs.
The Indoor Formula has more coco coir for longer moisture retention and less frequent watering. This is also a great mix for nearly all terrestrial tropical plants grown in the house.
If you grow in a greenhouse with automatic watering or you want to be able to water more often without fear of rotting roots, then the Greenhouse Formula is the one for you. This is also best for outdoor growing in wetter areas like those of you in Florida, Hawaii, or other humid places with frequent rain and ample moisture in the air. It is also recommended for those growers with a tendency to over water. There is only a smidge of coco coir in this mix, so please know it dries out quickly & water accordingly.
*The appearance can vary from batch to batch due to availability & because it is hand mixed in small batches, yet it will not affect the performance.
Available in 3 sizes, approx: 1/8 cf, 1/4 cf, and 1 cf
