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

Grow More® Mendocino Producer's Choice Hydro 05-11-26 (25 lb) — Hydroponic-Optimized NPK Formula for Precision Water-Culture Growing

Grow More® Mendocino Producer's Choice Hydro 05-11-26 is a precision water-soluble fertilizer with an NPK profile — 5% nitrogen, 11% phosphate, 26% potassium — specifically calibrated for the nutrient uptake dynamics and solution management requirements of hydroponic growing environments. The low-nitrogen, moderate-phosphate, high-potassium ratio reflects the efficient delivery of hydroponic systems, where roots have direct, constant access to nutrients and require a different macronutrient balance than soil-based media.

In soil-based growing, macronutrients must overcome the buffering and cation-exchange dynamics of the medium to reach plant roots. In hydroponic systems, nutrients are delivered directly in solution, allowing for precise control and higher potassium efficiency. The Hydro 05-11-26 accounts for this dynamic, delivering a potassium-forward formula that maximizes the advantages of water-culture growing while maintaining the phosphate support needed for strong root development and energy transfer in soilless systems.

Key Features & Benefits

• Hydroponic-Optimized NPK Ratio: The 05-11-26 profile is calibrated for the uptake efficiency of hydroponic systems — higher potassium relative to nitrogen takes advantage of direct root-zone nutrient access without the buffering effects of soil media.
• 26% Potassium for Hydro Performance: High soluble potash supports enzyme activation, water regulation, and cell wall strength in the high-intensity, fast-growth conditions typical of productive water-culture growing environments.
• 11% Phosphate for Root and Energy Systems: Moderate phosphate sustains the energy production and root metabolism critical in soilless systems where root integrity is especially important for nutrient and water uptake.
• Low Nitrogen for Controlled Vegetative Growth: Minimal nitrogen (5%) delivers what's needed for protein synthesis and chlorophyll production without overdriving vegetative extension in the controlled environment of a hydroponic system.
• 100% Water-Soluble — No Clogging: Dissolves completely in reservoir water with no insoluble residue, protecting pumps, emitters, and distribution tubing in recirculating hydroponic systems.

Who Should Use This

Designed for hydroponic cultivators running DWC, NFT, ebb-and-flow, aeroponics, or drip-to-waste systems who need a macronutrient formula built specifically for water-culture nutrient dynamics. Also suitable for coco coir growers who irrigate frequently and benefit from a potassium-forward formula that accounts for the high-frequency feeding conditions of open or recirculating systems.

Compatibility

Optimized for DWC, NFT, aeroponics, ebb-and-flow, and drip hydroponic systems. Compatible with all Grow More® Mendocino Producer's Choice formulas. Supplement with calcium-magnesium and chelated micronutrients for complete hydroponic nutrition. Monitor reservoir EC and pH regularly; adjust reservoir feed concentration based on plant uptake and EC drift.

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 nutrient 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 lead to overly vegetative growth. The 05-11-26 profile balances efficient growth with the structural and enzyme benefits of high potassium.

Can I use this formula in soil or coco coir?

While optimized for hydroponics, the Hydro 05-11-26 can be used in coco coir or other soilless media with frequent irrigation. It may be less ideal in heavily buffered soil media where the high potassium can interact with soil cation-exchange sites.

Is this suitable for the full crop cycle or specific stages?

The Hydro 05-11-26 is versatile enough for use across vegetative and early flowering stages. For late-stage flowering, consider supplementing or transitioning to a dedicated high-PK finishing formula like the Crystallizer 05-10-40 or Flower Hardener 00-37-37.

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

Yes — especially when using RO or purified water. Hydroponic systems strip natural water alkalinity and calcium/magnesium content. A dedicated calcium-magnesium supplement is essential alongside the Hydro formula for complete plant nutrition in water-culture growing environments.
