mcgeary organics HORTICULTURAL 5-4-3 Soil-less Media Fertilizer McGeary's horticultural fertilizer consists of McGeary Organics 5-3-4 blended with micronutrients. This fertilizer will supply plants growing in soil-less medias such as peat, bark, or coir with nutrients that these substrates do not contain.
Note that this fertilizer will not be allowed for use is soils by organic certifiers due to NOP regulations requiring a soil test that shows a need for micronutrients before micronutrients are added. Unlike most soil-less medias which are largely inert, it is essentially impossible to find a soil that requires all of the micronutrients contained in McGeary Organics Horticultural 5-3-4.
