Grow More® Sea Grow Bloom & Flower 4-26-26 — 25 lb

Grow More® Sea Grow Bloom & Flower 4-26-26 (25 lb) — High-PK Kelp-Enhanced Bloom Formula for Maximum Flower Development

Grow More® Sea Grow Bloom & Flower 4-26-26 is a specialized flowering fertilizer engineered around the macronutrient demands of the bloom phase — low nitrogen (4%), high phosphate (26%), and high potassium (26%) — enriched with botanical kelp extract containing naturally occurring plant hormones. The high P+K profile drives the energy production, flower site development, and structural maturation associated with productive, dense flowering, while the kelp fraction contributes cytokinins and auxins that enhance cell division and improve the plant's overall capacity to develop and fill reproductive structures.

The Sea Grow Bloom & Flower formula is part of Grow More's hybrid plant food line — combining the precision of targeted synthetic macronutrients with the biostimulant properties of seaweed extract, blood meal, organic carbon, amino acids, and carbohydrates. This comprehensive approach delivers a more complete biological environment than a simple NPK fertilizer, supporting both the plant's direct nutritional needs and the microbial activity in the root zone that improves nutrient availability and uptake efficiency. Available in the 25 lb format for all scales of indoor and outdoor growing environments.

Key Features & Benefits

• High-PK Bloom Profile (4-26-26): Low nitrogen keeps vegetative drive in check while high phosphate and potassium fuel the energy production, flower site development, and cell wall strength critical to productive flowering.
• Botanical Kelp Extract with Natural Plant Hormones: Cytokinins and auxins from the seaweed fraction support cell division and flower site development, enhancing the plant's natural capacity to produce and fill reproductive structures during the bloom phase.
• Blood Meal Nitrogen Source: Provides a naturally derived, slow-available nitrogen component that supports metabolic function without the sharp vegetative push of high-nitrate formulas.
• Amino Acids and Organic Carbon: Feed beneficial root zone microbes and provide organic building blocks for protein synthesis and secondary metabolite production during the demanding flowering stage.
• Carbohydrate Support: Natural carbohydrates from the kelp and organic carbon fraction sustain microbial life in soil and coco growing environments, improving the root zone biology that supports healthy, productive flowering.
• 100% Water-Soluble: Dissolves completely with no residue — compatible with drip, flood-and-drain, hydroponic reservoirs, and foliar spray applications.

Who Should Use This

Sea Grow Bloom & Flower 4-26-26 is ideal for growers who want both the precision of a bloom-specific macronutrient formula and the biological benefits of a kelp biostimulant in a single product. It is well suited for flowering vegetables, fruiting crops, ornamental flowering plants, and specialty crops grown in soil, coco coir, or hydroponic systems. The high-PK profile makes it particularly valuable for the mid-to-late flowering stage when phosphate and potassium demand is at its peak.

Compatibility

Compatible with soil, coco coir, rockwool, DWC, NFT, drip, and flood-and-drain systems. Best used from the onset of flowering through mid-to-late bloom. Supplement with a calcium-magnesium product and chelated micronutrient formula for complete nutrition. Can be used alongside Sea Grow All Purpose 16-16-16 during the transition from vegetative to flowering stages.

Frequently Asked Questions

How does Sea Grow Bloom & Flower differ from Sea Grow All Purpose?

Sea Grow All Purpose 16-16-16 uses a balanced 1:1:1 ratio suited for vegetative growth and general feeding. Sea Grow Bloom & Flower 4-26-26 shifts to a low-nitrogen, high-P+K profile specifically designed for the flowering stage, when plants require more phosphate for energy production and more potassium for flower development and cell wall integrity.

When should I transition from All Purpose to Bloom & Flower?

Begin transitioning as the plant enters the reproductive stage — when flower sites become visible. You can make an abrupt switch or gradually blend All Purpose with Bloom & Flower over 1–2 weeks to ease the NPK transition and minimize plant stress.

Does this formula contain enough calcium for flowering plants?

Sea Grow Bloom & Flower is a macronutrient and biostimulant formula. Calcium and magnesium demand remains high during flowering, so supplementing with a dedicated calcium-magnesium product is recommended, especially in systems using reverse osmosis or low-mineral water.

Can I use this for foliar feeding during flowering?

Yes, in dilute concentration during early-to-mid flower. Exercise caution with foliar feeding in late flower to avoid moisture accumulation on dense flower structures. Apply during low-light or lights-off periods to minimize leaf burn risk.

What is the source of the blood meal in this formula?

Blood meal is a naturally derived, high-nitrogen organic material used as one of the nitrogen sources in the Sea Grow Bloom & Flower formula. It provides a slower-releasing organic nitrogen component that supports metabolic function without driving aggressive vegetative growth during the bloom phase.
