General Hydroponics FloraMicro 5-0-1 vs Chelated Micronutrient Mix

These are not substitutes. FloraMicro is a complete base nutrient with nitrogen, potassium, calcium and trace elements, meant to be used with FloraGro and FloraBloom in General Hydroponics' three-part system. The chelated micronutrient mix is a trace-element component only, with no meaningful NPK, for growers building a custom program. Buy FloraMicro if you want a proven, simple base; buy the micronutrient mix if you already supply your own nitrogen, phosphorus and potassium and only need chelated iron and friends.

• Choose the FloraMicro if you want a ready base nutrient with calcium and trace elements that plugs into the Flora series and works in hydro, potting mix or soil.
• Choose the chelated micronutrient mix if you mix your own NPK salts and need a measured trace-element blend, especially chelated iron for soilless media.
