GH Flora Gro Pint (Case of 12)

Structural and Vegetative Growth Nutrient, Pint 12-Pack

Vegetative-stage plants need a different nutrient balance than flowering plants do — more support for structural growth and root development, less emphasis on the phosphorus and potassium that flowering draws on heavily. GH Flora Gro 2-1-6 is formulated specifically for that vegetative window, supplying nitrogen, phosphorus, potassium, and secondary minerals to build strong roots and support healthy structural growth.

Part of the General Hydroponics Flora Series, Flora Gro is designed to pair with Flora Bloom once plants transition into flowering.

Key Features & Benefits

• 2-1-6 nutrient ratio — formulated to stimulate structural and vegetative growth.
• Nitrogen, phosphorus, potassium, and secondary minerals — work together to build strong roots and support healthy growth.
• Works in soil and hydroponic systems — flexible across common growing methods.
• Part of a complete nutrient program — designed to pair with other Flora Series products across growth stages.

Who Should Use Flora Gro

This nutrient fits growers running plants through the vegetative stage in soil or hydroponic systems who want a dedicated vegetative-growth formula rather than a single all-stage product. Growers moving into flowering should pair Flora Gro with Flora Bloom.

About General Hydroponics Flora Series

Frequently Asked Questions

What does the 2-1-6 ratio mean?

The numbers refer to Flora Gro's nitrogen-phosphorus-potassium (N-P-K) ratio, formulated to support structural and vegetative growth rather than flowering.

Can I use Flora Gro in both soil and hydroponic systems?

Yes, it can be mixed with water and applied directly to soil or added to a hydroponic system.

When should I switch from Flora Gro to Flora Bloom?

Growers typically switch once plants transition out of vegetative growth and begin flowering, at which point Flora Bloom's phosphorus- and potassium-forward ratio takes over.

How do I avoid over-fertilizing with Flora Gro?

Follow label application rates and monitor nutrient solution pH regularly, since over-fertilization can lead to nutrient burn regardless of which formula is used.

Is Flora Gro used alone or as part of a larger program?

It's typically used as part of a complete Flora Series nutrient program alongside other stage-specific products for optimal results.
