Epic for your cactus

This is such a great product. I use this for my cactus garden and it helps them keep infections and nasties at bay - Sydney = humid for cactus and I have had to put in an extremely hydrophobic soil mix. Adding the CalMag has been a revelation. I'll never buy anywhere else. The service and products are beyond expectations.
