Plant Marvel Water Soluble Fertilizers

Plant Marvel is the "gold standard" in the water soluble fertilizer industry with  complete essential nutrient content. Established in 1922, Plant Marvel Laboratories pioneered and popularized the use of water soluble fertilizers.  We introduced our original 12-31-14 General Purpose Hi Phosphate formulation over 90 years ago helping to fuel the growth of soilless growing and hydroponics.  Some years later we found a way to incorporate soluble forms of minor and trace elements into our expanding line of soluble N-P-K fertilizers.
