General Hydroponics FloraBloom 0-5-4 Bloom Nutrient, 1 Gallon — P & K Boost for Flowering

General Hydroponics FloraBloom 0-5-4 is a liquid concentrate formulated to support plants through their flowering, fruiting, and seed-production stages when used alone or combined with the FloraSeries nutrients.

FloraBloom is part of General Hydroponics' three-part FloraSeries and supplies phosphorus and potassium-rich feed to encourage reproductive development in a wide range of crops. Designed for hydroponics and as a supplement for soil or container plants, this 1-gallon bottle mixes with FloraMicro and FloraGro so growers can tailor nutrient ratios to each growth phase and crop type. It’s a component for growers who prefer precise, customizable feeding schedules rather than single-solution fertilizers.

How does FloraBloom help during flowering and fruiting?

FloraBloom emphasizes the elements plants need during reproductive growth—primarily phosphorus and potassium—to support bud set, flower development, and fruiting. When blended with FloraMicro and FloraGro, it completes the nutrient profile for balanced, stage-specific feeding.

• High phosphorus and potassium content for reproductive stages
• Complements FloraMicro for trace elements and nitrogen
• Works in hydroponic systems and as a supplement for potted plants

How do I mix FloraBloom with the rest of the FloraSeries?

FloraBloom is built to function as one third of a modular feeding program. Typical use involves following manufacturer ratios: combine FloraGro, FloraMicro, and FloraBloom in water according to the growth stage, then adjust EC and pH for your system and crop.

• Start with a base FloraMicro dose, then add FloraGro for vegetative growth or FloraBloom for flowering
• Adjust concentrations progressively across early, mid, and late bloom phases
• Always measure and correct pH and electrical conductivity after mixing

What systems and plants are best suited for this product?

FloraBloom is versatile and compatible with most hydroponic setups—DWC, ebb-and-flow, NFT, and drip—as well as soil and container gardening as a nutrient supplement. It’s intended for growers who need control over nutrient ratios during reproductive phases rather than a one-size-fits-all feed.

• Ideal for hydroponic growers using FloraSeries programs
• Useful as a supplemental bloom booster for indoor and greenhouse crops
• Appropriate for flowering ornamentals, fruiting vegetables, and seed development

Who is this for? General Hydroponics FloraBloom 0-5-4 is aimed at hobbyists and commercial growers who want a customizable, science-driven nutrient program. If you prefer to mix feeding solutions to match crop stage and system type—or you need a reliable phosphorus-potassium component to complement trace-element-rich FloraMicro—this product allows precise control over bloom and fruit development. It’s not an all-in-one fertilizer; it performs best when used as part of the FloraSeries or when supplementing existing feeding regimens.
