Grow More® Mendocino Producer's Choice Flower and Bloom 06-30-30 — 25 lb

Grow More® Mendocino Producer's Choice Flower and Bloom 06-30-30 (25 lb) — High-PK Flowering Formula for Robust Bloom Development

Grow More® Mendocino Producer's Choice Flower and Bloom 06-30-30 delivers a high-phosphate, high-potassium NPK profile (30% P, 30% K) with low nitrogen (6%) — a powerful flowering formula engineered to fuel productive bloom development from first flower through mid-cycle peak. The balanced high P+K ratio drives the dual demands of reproductive energy production (phosphate) and structural flower development (potassium) while keeping nitrogen low enough to maintain the plant's focus on flower production over vegetative growth.

As part of the Mendocino Producer's Choice line, Flower and Bloom 06-30-30 is a 100% water-soluble powder formulated for precision indoor growing environments where macronutrient control by growth stage is standard practice. It can be used as a primary bloom formula or blended with other Producer's Choice products to progressively shift NPK ratios as the crop advances through distinct phases of the flowering cycle.

Key Features & Benefits

• 30% Phosphate for Bloom Energy and Development: High available phosphate (P₂O₅) powers ATP synthesis, root metabolism, and the energy-intensive process of flower and fruit set throughout the bloom phase.
• 30% Potassium for Flower Quality and Density: Matching high soluble potash (K₂O) activates key enzymes, regulates water balance, and drives cell wall development — the foundation of dense, well-formed flowers.
• Low Nitrogen (6%) Maintains Bloom Focus: Minimal nitrogen keeps the plant focused on reproductive output rather than vegetative extension, preserving the hormonal balance that favors flower development.
• Equal P:K Ratio for Stage Balance: The symmetrical 30:30 phosphate-to-potassium ratio reflects the balanced macronutrient demand of mid-cycle flowering, where both energy production and structural development are simultaneously active.
• 100% Water-Soluble: Dissolves completely without residue in cold or warm water, compatible with all hydroponic and soil-based irrigation systems.

Who Should Use This

Ideal for indoor cultivators, commercial greenhouse growers, and hydroponic operators who need a powerful, clean bloom formula with equal high-P and high-K delivery. Works well as a primary flowering nutrient from bloom onset through mid-cycle, and pairs effectively with the Crystallizer 05-10-40 or Flower Hardener 00-37-37 as crops move into the finishing phase.

Compatibility

Compatible with all Grow More® Mendocino Producer's Choice formulas. Supplement with a calcium-magnesium and chelated micronutrient product for a complete bloom program. Can be blended with Crystallizer 05-10-40 in late flower to increase the potassium ratio further. Compatible with drip, DWC, NFT, flood-and-drain, and foliar applications.

Frequently Asked Questions

How does Flower and Bloom 06-30-30 differ from Bloom 01-10-18?

Bloom 01-10-18 has a much lower NPK concentration with minimal nitrogen, suited for early bloom transition. Flower and Bloom 06-30-30 has higher absolute P and K values with slightly more nitrogen — it delivers more total phosphate and potassium per application, making it more suitable for mid-cycle flowering when the plant's macronutrient demand peaks.

When should I use Flower and Bloom versus Flower Hardener?

Use Flower and Bloom 06-30-30 through mid-cycle flowering to fuel flower development and energy production. Transition to Flower Hardener 00-37-37 in the late stage when you want to eliminate nitrogen entirely and push the plant toward structural maturation and compaction.

Is 06-30-30 suitable for the full flowering stage?

It can be used throughout flowering, but many growers use it primarily through mid-cycle, then transition to the Crystallizer or Flower Hardener in the final weeks for a potassium-intensive finishing phase. This stage-specific approach is common in advanced high-production growing environments.

Do I need a separate micronutrient supplement with this?

Yes. Flower and Bloom 06-30-30 is a macronutrient formula. A dedicated calcium-magnesium and chelated micronutrient supplement is needed alongside it to provide complete plant nutrition during the demanding flowering cycle.
