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

Balanced NPK Fertilizer Enriched With Kelp Hormones for Every Stage of Growth

A synthetic balanced fertilizer covers the macronutrient basics, but it does nothing for root-zone biology. Grow More Sea Grow All Purpose 16-16-16 merges a perfectly equal 16-16-16 NPK ratio with botanical kelp extract carrying naturally occurring cytokinins and auxins, plus organic carbon, amino acids, and carbohydrates that support both the plant and the microbial life around its roots.

Suited to vegetables, fruits, flowers, herbs, and specialty crops across soil, coco coir, and hydroponic environments, the 25 lb bag gives home growers, boutique cultivators, and professional operations one versatile all-purpose formula rather than juggling separate synthetic and biostimulant products.

Key Features & Benefits

• Balanced 16-16-16 NPK: Equal macronutrients support every phase of growth, from seedling establishment through vegetative growth and early flowering.
• Botanical Kelp Extract: Naturally occurring cytokinins and auxins stimulate root proliferation, cell division, and overall plant vigor.
• Amino Acids and Organic Carbon: Support microbial activity in the root zone and improve nutrient-uptake efficiency.
• Carbohydrate Energy Support: Feeds beneficial microbes in soil and coco environments, improving the root-zone biology behind healthy growth.
• 100% Water-Soluble: Dissolves completely with no residue, safe for drip systems, foliar spray, and hydroponic reservoirs.

Who Should Use This

Growers who want the efficiency of a complete balanced nutrient combined with the biological benefits of a kelp biostimulant are the direct fit — especially mixed-variety growing environments, home gardens, and hydroponic operations where one versatile all-stage formula simplifies the nutrition program.

Frequently Asked Questions

What makes Sea Grow different from a standard balanced fertilizer?

Beyond the 16-16-16 macronutrient profile, Sea Grow incorporates botanical kelp extract containing naturally occurring cytokinins and auxins that stimulate root development and cell division, plus amino acids and organic carbon that support root-zone biology in ways a standard synthetic fertilizer does not. The result is a single product that covers both direct feeding and root-zone biology instead of requiring two separate inputs.

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

It provides a complete macronutrient base, but for best results in high-production environments, supplement with a calcium-magnesium product and chelated micronutrient formula, since Sea Grow All Purpose doesn't supply enough calcium or magnesium on its own for fast-growing crops. Pairing it with a dedicated cal-mag product closes that gap without complicating the rest of the feeding schedule.

When during the crop cycle does Sea Grow All Purpose work best?

The balanced 16-16-16 performs well through vegetative growth and early flowering. For mid-to-late flowering, many growers transition to a higher-PK bloom formula 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 suits foliar application. Dilute to a lower concentration than root-drenching rates and apply during low-light or lights-off periods to reduce leaf-burn risk.
