General Hydroponics FloraBloom

General Hydroponics FloraBloom is one of the three essential components of the legendary FloraSeries nutrient system, the original 3-part hydroponic nutrient program introduced in 1976. Designed specifically for flowering, fruiting, and reproductive growth, FloraBloom supplies elevated levels of phosphorus, potassium, magnesium, and sulfur to help plants develop abundant flowers, larger fruits, and improved crop quality.

Unlike one-size-fits-all fertilizers, FloraSeries allows growers to adjust the ratios of FloraGro, FloraMicro, and FloraBloom throughout the plant's life cycle. This flexible "building block" approach gives complete control over nutrition from seedlings and vegetative growth through flowering, fruiting, and harvest.

FloraBloom delivers 5% available phosphate and 4% soluble potash while supplying magnesium and sulfur to support flower production, energy transfer, photosynthesis, and nutrient transport. Combined with FloraMicro and FloraGro, it creates a balanced nutrient program that adapts to virtually every stage of plant development.

Suitable for hydroponics, coco coir, soil, peat-based mixes, rockwool, water culture, and other growing methods, FloraBloom remains fully water soluble for fast nutrient availability and dependable performance in both recirculating and drain-to-waste systems.

Every batch is manufactured under strict quality-control standards to ensure consistent mineral content and reliable performance season after season.

For proper mixing, always add FloraMicro to fresh water first, stir thoroughly, then add FloraGro if required, followed by FloraBloom. Never combine concentrated FloraSeries nutrients together before dilution.

Available in multiple container sizes, FloraBloom is trusted by home gardeners, commercial growers, greenhouse operations, and research facilities around the world.

Original FloraSeries Formula

FloraBloom is part of the original FloraSeries nutrient system introduced in 1976.

Together with FloraMicro and FloraGro, it provides a flexible feeding program that adapts to every stage of plant growth.

Designed for Flowering & Fruiting

FloraBloom supplies the nutrients plants require during reproductive growth.

Its phosphorus-rich formula supports flower formation, fruit development, and overall crop production.

Building Block Nutrition System

FloraSeries allows growers to fine-tune nutrient ratios throughout the growing cycle.

Simply adjust the balance of FloraGro, FloraMicro, and FloraBloom to match changing plant requirements.

High Phosphorus Formula

FloraBloom provides 5% available phosphate to support flowering, fruit set, root activity, and energy transfer throughout the plant.

Potassium for Healthy Development

Containing 4% soluble potash, FloraBloom supports nutrient movement, water regulation, and overall plant vigor during flowering.

Magnesium & Sulfur Support

The formula contains 1.5% magnesium and 1% sulfur to support chlorophyll production, photosynthesis, enzyme activity, and healthy plant metabolism.

Fully Water Soluble

The concentrated liquid formula dissolves completely in water for rapid nutrient availability across hydroponic and traditional growing systems.
