Grow More® Sea Grow All Purpose 16-16-16 — 25 lb

Grow More® Sea Grow All Purpose 16-16-16 (25 lb) — Balanced Kelp-Enhanced Nutrition for All Plants and Growth Stages

Grow More® Sea Grow All Purpose 16-16-16 is a premium hybrid fertilizer that merges the precision of a perfectly balanced synthetic NPK formula with the biological richness of botanical seaweed extract. The equal 16-16-16 macronutrient ratio delivers balanced nitrogen, phosphate, and potassium to support every phase of the plant lifecycle, while the naturally occurring plant hormones — cytokinins and auxins — present in the kelp fraction work to stimulate root development, promote cell division, and improve overall plant vitality. Additional organic carbon, amino acids, and carbohydrates round out a comprehensive formula designed to support both the plant and the microbial life in its root zone.

The Sea Grow All Purpose is one of Grow More's most versatile formulations — suitable for vegetables, fruits, flowers, herbs, and specialty crops across soil, coco coir, and hydroponic growing environments. Its complete, balanced NPK makes it an ideal general-purpose nutrient for growers who want the combined benefits of kelp biostimulants and synthetic precision without managing separate products. The 25 lb format provides the right volume for home growers, boutique cultivators, and professional operations alike.

Key Features & Benefits

• Balanced 16-16-16 NPK: Equal macronutrients across nitrogen, phosphate, and potassium support every phase of plant growth — from seedling establishment through vegetative growth and early flowering — without overdriving any single element.
• Botanical Kelp Extract with Natural Plant Hormones: The seaweed fraction delivers cytokinins and auxins that stimulate root proliferation, encourage cell division, and improve plant vigor — biological benefits that synthetic nutrients alone cannot provide.
• Amino Acids and Organic Carbon: Support microbial activity in the root zone and improve the efficiency of nutrient uptake by providing the organic building blocks that fuel biological activity in living soils and growing media.
• Carbohydrate Energy Support: Natural carbohydrates from the kelp fraction feed beneficial microbes in soil and coco growing environments, improving the root zone biology that underpins healthy plant growth.
• Versatile Application: Compatible with all crop types, growing media, and irrigation systems — a single all-purpose formula suitable from seedling through early flowering.
• 100% Water-Soluble: Dissolves completely with no insoluble residue, safe for use in drip systems, foliar spray, hydroponic reservoirs, and soil/coco irrigations.

Who Should Use This

Sea Grow All Purpose 16-16-16 is ideal for growers who want the efficiency of a complete, balanced nutrient combined with the biological benefits of a kelp biostimulant. It is well suited for mixed-variety growing environments, home gardens, greenhouse production, and hydroponic operations where a versatile all-stage formula simplifies the nutrition program without sacrificing performance. It pairs naturally with calcium-magnesium and micronutrient supplements for a complete feeding regimen.

Compatibility

Compatible with soil, coco coir, rockwool, and hydroponic systems including DWC, NFT, drip, and flood-and-drain. Mix at the recommended rate in water and apply as a root drench, reservoir top-up, or foliar spray. Supplement with a calcium-magnesium and chelated micronutrient product for complete plant nutrition across all growth stages.

Frequently Asked Questions

What makes Sea Grow different from a standard balanced fertilizer?

In addition to the 16-16-16 macronutrient profile, Sea Grow incorporates botanical kelp extract containing naturally occurring cytokinins and auxins — plant growth hormones that stimulate root development and cell division. The added amino acids and organic carbon further support root zone biology in ways that standard synthetic fertilizers do not.

Can I use Sea Grow All Purpose as my only nutrient?

The 16-16-16 provides a complete macronutrient base, but for best results in high-production growing environments, supplement with a calcium-magnesium product and a chelated micronutrient formula. Sea Grow All Purpose does not contain sufficient calcium or magnesium for the full demands of fast-growing crops.

Is this formula suitable for the full crop cycle?

The balanced 16-16-16 performs well through vegetative growth and early flowering. For mid-to-late flowering, many growers transition to a higher P+K formula such as Sea Grow Bloom & Flower 4-26-26 to match the increased phosphate and potassium demand of the reproductive stage.

Can I use Sea Grow for foliar feeding?

Yes. The 100% water-soluble formula is suitable for foliar application. Dilute to a lower concentration than root drenching rates and apply during low-light or lights-off periods to minimize the risk of leaf burn.

Is the kelp in this product certified organic?

Sea Grow uses botanical kelp extract as an ingredient for its naturally occurring biostimulant content. For specific organic certification status, refer to the product label or contact Grow More directly for the most current compliance information.
