As you Are am also a beginner in gardening even though a senior senior citizen. Have a small roof garden Where I am growing Archid flowers, other types of small plants and also some vegitables. As a starter am trying to experiment use of new meterials of gardening. Your material is used as a mix of potting material hence either success or failure cannot be attributed to one material. I am sure your material will definitely increase the efficacy. Once I use the Meterial will revert back.
