General Hydroponics FloraGro 2-1-6 - 6gal

Vegetative Leg of the Flora 3-Part Nutrient System, 6gal

Stem elongation, leaf expansion, and root development all draw on nitrogen and potassium during the vegetative stage, and a bloom-formulated fertilizer will not supply either in the right ratio. General Hydroponics FloraGro 2-1-6 is the vegetative-growth component of the Flora 3-part nutrient system, supplying nitrogen and potassium to drive structural and foliar development in hydroponic, coco, and soil systems.

This 6gal container provides a mid-range supply for growers maintaining multi-system vegetative programs over extended periods.

Key Features & Benefits

• Nitrogen and Potassium Focus — 2-1-6 ratio drives stem elongation, leaf expansion, and root development
• Liquid Formula — mixes directly into nutrient solutions in any reservoir system
• Compatible with All Media — works in hydroponic, coco coir, perlite, and soil systems
• Flora 3-Part System Component — pairs with FloraMicro and FloraBloom for stage-by-stage adjustment

Who Should Use FloraGro

Growers running the GH Flora 3-part system who need precise vegetative nutrition for structural and foliar development, across hydroponic, coco, or soil setups, will find FloraGro built for that stage.

About General Hydroponics

General Hydroponics got its start in 1976 when founder Lawrence Brooke began developing nutrient formulas out of a Berkeley, California garage; the company has been part of the Hawthorne Gardening Company brand portfolio, a Scotts Miracle-Gro subsidiary, since April 2015. FloraGro supplies the nitrogen- and potassium-forward vegetative leg of its Flora 3-part nutrient system.

Frequently Asked Questions

What does FloraGro 2-1-6 supply during vegetative growth?

It supplies nitrogen and potassium at a 2-1-6 ratio to drive stem elongation, leaf expansion, and root development. That nitrogen-forward profile is proportioned for structural growth rather than flowering.

When should I switch from FloraGro to FloraBloom?

Switch as plants move from vegetative growth into flowering, shifting the mixing ratio toward FloraBloom per the Flora Series feeding chart rather than stopping FloraGro abruptly. FloraMicro stays in the mix at every stage regardless of that shift.

What growing media is FloraGro compatible with?

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

Can I use FloraGro without FloraMicro and FloraBloom?

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 bloom-phase phosphorus the other two components supply. The full three-part chart is the intended use.

Which FloraGro size fits a small home hydroponic setup?

The 16oz and 32oz bottles suit home growers and small hydroponic setups evaluating the Flora 3-part program. Larger commercial operations typically move up to the 6gal through 275gal Tote sizes.
