Grow More® Mendocino Producer's Choice Base 14.5-0-0 — 25 lb

Grow More® Mendocino Producer's Choice Base 14.5-0-0 (25 lb) — Pure Nitrogen Base Supplement for Independent N Management

Grow More® Mendocino Producer's Choice Base 14.5-0-0 is a concentrated nitrogen-only powder supplement designed to independently raise the nitrogen content of a nutrient solution without altering phosphorus or potassium levels. At 14.5% total nitrogen and zero phosphate or potassium, this formula gives growers surgical precision when managing macronutrient ratios — an essential capability for cultivators running advanced, stage-specific nutrition programs in high-production indoor growing environments.

The Base 14.5-0-0 is particularly valuable for growers using multi-part fertilizer systems who need to fine-tune nitrogen levels independently without disrupting carefully calibrated P:K ratios. It can be added to any stage of a feeding program to correct nitrogen deficiency, push vegetative growth, or serve as a foundational nitrogen source when formulating custom nutrient solutions. As part of the Mendocino Producer's Choice line, it dissolves completely with no insoluble residue.

Key Features & Benefits

• 14.5% Pure Nitrogen — No P or K: Delivers nitrogen independently of phosphorus and potassium, giving growers precise control over macronutrient ratios without disrupting existing feed formulas.
• Nitrogen Deficiency Correction: Quickly addresses nitrogen deficiencies — yellowing leaves, slow growth, pale foliage — by boosting available nitrogen in the root zone without adding unnecessary P or K.
• Custom Formula Building Block: An essential component for growers building custom nutrient programs from scratch, providing a clean nitrogen source to balance with other macro and micro components.
• Versatile Application Timing: Can be applied at any growth stage where additional nitrogen is warranted — vegetative push, recovery feeding, or as part of a precision stage-specific nutrient formula.
• 100% Water-Soluble: Dissolves completely in cold or warm water with no sediment, suitable for drip systems, flood-and-drain, NFT, and foliar applications without clogging emitters or nozzles.

Who Should Use This

Designed for advanced growers who manage macronutrient ratios independently and need a clean nitrogen source to supplement or balance existing nutrient programs. Particularly useful for cultivators building custom formulas, operating multi-stage programs, or correcting nitrogen deficiencies without impacting phosphate and potassium levels in their nutrient solution.

Compatibility

Fully compatible with all Grow More® Mendocino Producer's Choice formulas and most commercial nutrient lines. Mix into nutrient solutions at the required rate after primary nutrients have been dissolved. Monitor solution EC and adjust total nitrogen contribution based on crop stage and target feeding levels. Compatible with drip, flood-and-drain, NFT, DWC, and foliar systems.

Frequently Asked Questions

Why would I use a 14.5-0-0 formula instead of a complete fertilizer?

The 14.5-0-0 is used when you need to adjust nitrogen levels independently without changing the P:K balance of your existing nutrient program. This is particularly valuable in advanced nutrient management where each macronutrient is calibrated separately for a specific crop stage or response.

What forms of nitrogen does this product contain?

Mendocino Producer's Choice Base 14.5-0-0 contains multiple nitrogen forms — ammoniacal and water-soluble nitrogen — to support rapid uptake and sustained availability. Check the product label for the specific guaranteed analysis breakdown.

Can I use this as my only nitrogen source?

It can serve as a nitrogen source, but it provides no phosphate, potassium, or micronutrients. It's most effective as part of a complete nutrient program, used to supplement or fine-tune nitrogen levels rather than as a standalone complete fertilizer.

Is this suitable for use during flowering?

The Base 14.5-0-0 can be used during flowering if nitrogen correction is needed, but most bloom-stage programs reduce nitrogen to encourage phosphate and potassium uptake for flower development. Use carefully during late flower and discontinue as harvest approaches.
