Manufactured by Greencare The nutritional program at Michigan State University is vastly different from the majority of recommendations circulating within the horticultural world about the fertilization of orchids. Several years after the release of their wildly popular original blends comes a new blend called K-Lite. The K-Lite fertilizer formula (12-1-1-10Ca-3Mg) has been developed in response to studies suggesting excessive potassium, whether applied, obtained from, or accumulated in growing media can have a negative impact on the health of plants, especially in the absence of adequate calcium and magnesium levels. The RO Blend was the first fertilizer to address this, the K-Lite being an improvement on that formula. Some key data which was used to develop this formula is as follows: - Tissue data analysis from wild collected plants showed that calcium (Ca), and magnesium (Mg) concentrations were often greater than that of potassium (K), yet most fertilizers have it the other way ar
