General Hydroponics FloraMicro

General Hydroponics FloraMicro is the foundation of the legendary FloraSeries, the original 3-part nutrient system introduced in 1976. Working alongside FloraGro and FloraBloom, FloraMicro provides the essential primary, secondary, and micronutrients plants need throughout every stage of growth.

As the core building block of the FloraSeries, FloraMicro supplies nitrogen, calcium, potassium, and a complete spectrum of chelated micronutrients that support vigorous growth, healthy foliage, and optimal nutrient uptake. By adjusting the ratios of FloraMicro, FloraGro, and FloraBloom, growers can create customized feeding programs for seedlings, vegetative growth, flowering, fruiting, and harvest.

Suitable for hydroponics, coco coir, soil, peat-based mixes, and soilless media, FloraMicro delivers exceptional flexibility for home gardeners, greenhouse growers, and commercial producers alike. Its fully soluble formula mixes easily into nutrient reservoirs and is batch-tested for consistent quality and dependable performance.
