A must for orchids and all plants!
This is a high quality organic potting mix nutrient which consists of 96% calcium carbonate and many micronutrients. Provides a long-lasting, steady release of nutrients which regulates pH levels, improves fertilizer uptake, promotes healthy cellular structure, and reduces plant stress. Compared to agricultural lime, oyster shell chips have more irregular surface areas which increase interaction with the soil and create a better habitat for soil microbes. This allows the oyster shell chips to feed the potting mix as well as reduce potting mix compaction. In turn this creates a stronger and more expansive root system and a more viable and productive plant. USED BY PROFESSIONAL HAWAIIAN ORCHID GROWERS!
