Know before you buy

Yes, Seaplex is a water-soluble concentrate designed to mix easily into nutrient solutions. Because it is highly refined, it is safe for use in hydroponic systems, drip irrigation, and traditional soil applications.
Seaplex is a supplement rather than a primary fertilizer. With an NPK ratio of 0.01-0-0, it provides trace micronutrients and organic compounds to boost vitality, but you should continue using a balanced fertilizer to meet your plant's primary nutritional needs.
Cold-processing preserves the delicate enzymes, hormones, and vitamins found in the raw Ascophyllum nodosum kelp. High-heat processing can destroy these beneficial compounds, making cold-processed options more effective for plant health.
Yes, it is highly versatile and suitable for a wide range of plants, including vegetables, flowers, trees, shrubs, and houseplants. It is an organic-certified supplement that provides a gentle, natural boost to any garden.
