Maxsea Grow 16-16-16 is a water-soluble, seaweed-enriched all-purpose fertilizer formulated to feed indoor and outdoor plants with balanced N-P-K plus trace elements.
Designed for year-round use, this concentrated powder dissolves easily in water to supply nitrogen, phosphorus and potassium along with a broad spectrum of secondary nutrients and micronutrients. The formula also contains seaweed granules that introduce more than 60 naturally occurring elements, supporting resilient foliage, quality blooms and productive fruiting without needing separate supplements.
Mix the recommended amount into water for a foliar spray or soil drench depending on plant needs; frequency and dilution change by crop and season. Use lower concentrations for seedlings and more mature plants at active growth and flowering stages.
This product delivers an equal 16-16-16 N-P-K balance plus sulfur and essential micronutrients like iron, manganese, zinc, copper, boron and molybdenum. The combination supports balanced leaf growth, root development, flower production and overall metabolic functions without the need for many separate additives.
The seaweed granules provide a natural range of trace elements and organic-based compounds that can enhance stress tolerance and nutrient uptake. These extra elements complement the primary nutrients and help plants make use of available fertilizer more effectively.
Keep the container sealed and stored in a cool, dry place away from direct sunlight and out of reach of children and pets. Use measuring tools for consistent dosing, and rinse equipment after mixing to avoid residue buildup.
Who is this for: Maxsea Grow 16-16-16 is suited to hobby gardeners, houseplant enthusiasts, and small-scale vegetable growers who want a single, water-soluble fertilizer that covers macronutrients and microelements while bringing the nutritional variety of seaweed into routine feeding. It works well for plants at all life stages when used according to label rates and is a practical choice for anyone seeking a balanced, easy-to-mix solution for consistent garden performance.
Q: Can I use Maxsea Grow on seedlings?
A: Yes — use a weaker dilution and apply less frequently to avoid burning young roots.
Q: Is this fertilizer safe for edibles?
A: Yes — follow label instructions for application rates and pre-harvest intervals if specified.
