Grow More® Mendocino Producer's Choice Hydro 05-11-26 — 25 lb

Hydroponic-Calibrated Powder Built for the Uptake Dynamics of Water-Culture Growing

Soil buffers and cation-exchange dynamics change how a plant actually experiences a given NPK ratio, so a formula built for soil often isn't calibrated right for a reservoir where roots have constant, direct access to solution. Grow More Mendocino Producer's Choice Hydro 05-11-26 is a precision water-soluble fertilizer with 5% nitrogen, 11% phosphate, and 26% potassium, specifically calibrated for the nutrient uptake dynamics and solution management requirements of hydroponic systems.

The low-nitrogen, potassium-forward ratio takes advantage of direct root-zone nutrient access, and the 25 lb bag dissolves completely in reservoir water with no insoluble residue that could clog pumps or emitters.

Key Features & Benefits

• Hydroponic-Optimized NPK Ratio: The 05-11-26 profile is calibrated for the uptake efficiency of hydroponic systems without the buffering effects of soil media.
• 26% Potassium for Hydro Performance: Supports enzyme activation, water regulation, and cell wall strength in fast-growth, water-culture conditions.
• 11% Phosphate for Root and Energy Systems: Sustains energy production and root metabolism in soilless systems.
• Low Nitrogen for Controlled Vegetative Growth: Delivers what's needed for protein synthesis and chlorophyll production without overdriving vegetative extension.
• 100% Water-Soluble, No Clogging: Dissolves completely in reservoir water, protecting pumps, emitters, and distribution tubing.

Who Should Use This

Hydroponic cultivators running DWC, NFT, ebb-and-flow, aeroponics, or drip-to-waste systems who need a formula built for water-culture nutrient dynamics are the direct fit, along with coco coir growers who irrigate frequently.

About Grow More Inc.

Frequently Asked Questions

Why is the potassium so much higher than nitrogen in this formula?

In hydroponic systems, roots have constant, direct access to nutrient solution, making uptake more efficient than in soil. Potassium is heavily demanded by actively growing plants in these conditions, while excess nitrogen in a high-uptake environment can push overly vegetative growth.

Can I use this formula in soil or coco coir?

While optimized for hydroponics, it can be used in coco coir or other soilless media with frequent irrigation, though it may be less ideal in heavily buffered soil media where the high potassium can interact with cation-exchange sites. In soil, consider a lower application rate and monitor for interactions with existing amendments.

When during the crop cycle does Hydro 05-11-26 work best?

It's versatile enough for vegetative and early flowering stages. For late-stage flowering, consider supplementing or transitioning to a dedicated high-PK finishing formula.

Do I need to supplement with calcium and magnesium in hydroponics?

Yes, especially when using RO or purified water, since hydroponic systems strip natural water alkalinity and calcium and magnesium content. A dedicated calcium-magnesium supplement is essential alongside the Hydro formula.
