General Hydroponics FloraBloom 0-5-4 - 2.5gal

Bloom-Phase Leg of the Flora 3-Part Nutrient System, 2.5gal

Flower set, fruit development, and essential-oil production all draw heavily on phosphorus and potassium, and a general-purpose fertilizer rarely supplies enough of either during that stage. General Hydroponics FloraBloom 0-5-4 is the bloom-phase component of the Flora 3-part nutrient system, delivering phosphorus and potassium to support flowering and fruiting in hydroponic, coco, and soil systems.

This 2.5gal container provides a larger supply for mid-scale growers and commercial flowering operations.

Key Features & Benefits

• Phosphorus and Potassium Focus — 0-5-4 ratio fuels flowering and fruiting without excess nitrogen
• Liquid Formula — dilutes and mixes directly into any nutrient solution
• Compatible with All Media — performs in hydroponic, coco coir, perlite, and soil systems
• Flora 3-Part System Component — pairs with FloraMicro and FloraGro for a complete staged program

Who Should Use FloraBloom

Growers using the GH Flora 3-part system who want precise control over bloom-phase phosphorus and potassium levels, across hydroponic, coco, or soil setups, will find FloraBloom built for that stage.

About General Hydroponics

Since its founding in 1976 by Lawrence Brooke in a Berkeley, California garage, General Hydroponics has grown into part of the Hawthorne Gardening Company brand portfolio, a subsidiary of The Scotts Miracle-Gro Company, following its April 2015 acquisition. FloraBloom supplies the phosphorus- and potassium-heavy bloom leg of its Flora 3-part nutrient system.

Frequently Asked Questions

What does FloraBloom 0-5-4 supply during flowering?

It supplies phosphorus and potassium to support flower set, fruit development, and essential-oil production, with no added nitrogen at this stage. That 0-5-4 ratio is proportioned specifically for the bloom phase rather than general-purpose feeding.

How does FloraBloom fit into the full Flora 3-part system?

It is the bloom-phase leg, working alongside FloraMicro for calcium and micronutrients and FloraGro for vegetative-stage nitrogen. All three follow the same Flora Series feeding chart, with the mixing ratio shifting toward FloraBloom as plants move into flowering.

What growing media is FloraBloom compatible with?

It performs in hydroponic, coco coir, perlite, and soil growing systems without reformulation. That flexibility lets growers standardize on FloraBloom even if they run more than one media type.

Can I use FloraBloom without FloraMicro and FloraGro?

It is designed as one leg of the three-part system, so using it alone would leave a plant short on the calcium, micronutrients, and vegetative-stage nitrogen the other two components supply. Some growers still dose it alone briefly, but the full three-part chart is the intended use.

Which FloraBloom size fits a small home hydroponic setup?

The 16oz and 32oz bottles suit home growers and small hydroponic setups running the Flora 3-part program. As reservoir volume grows, most operations step up through the 1gal, 2.5gal, and 6gal sizes before reaching drum or tote quantities.
