GreenPlanet Nutrients Ocean Magic Kelp Additive

Cold-pressing extracts kelp without applying heat, which preserves the temperature-sensitive compounds that make kelp biologically valuable — including amino acids, natural enzymes, and biostimulants. Heat-based processing methods can denature these compounds, reducing their functional potency before the product ever reaches your plants.

GreenPlanet's cold-press approach ensures Ocean Magic retains the full mineral and nutrient profile of raw Atlantic Sea Kelp, delivering maximum efficacy with each application.

For foliar applications, GreenPlanet recommends starting in weeks 2 to 4 of the grow stage, then continuing once weekly for the following 2 to 3 weeks. Always spray on dry leaves when no rain or high-humidity conditions are expected to ensure proper absorption and avoid fungal issues.

For root feeding, Ocean Magic can be incorporated into your regular watering schedule throughout the vegetative stage at 0.5 ml/L (2 ml/Gal), soaking the growing medium thoroughly with each application.

Root feeding delivers Ocean Magic's kelp compounds directly into the rhizosphere, where they support root zone development, improve nutrient uptake from the medium, and stimulate beneficial microbial activity. This is the primary application method and the one most directly tied to yield improvements at harvest.

Foliar spraying introduces the kelp-derived nutrients and biostimulants through the leaf surface for faster systemic uptake — a useful complement when you want a more immediate plant response or when root zone conditions limit absorption. Note that the foliar rate is significantly higher at 5 ml/L (19 ml/Gal) versus the root feed rate of 0.5 ml/L (2 ml/Gal).

Ocean Magic contributes only soluble potassium (K₂O at 5.0%) with zero nitrogen or phosphorus. At the root feed rate of 0.5 ml/L, the PPM contribution is minimal and unlikely to significantly alter your overall nutrient balance when used alongside a standard GP3 base nutrient program.

As with any additive, it's good practice to monitor your total PPM after incorporation — especially if you are already using other potassium-contributing supplements in your stack.

Atlantic Sea Kelp contains naturally occurring biostimulants — including cytokinins and other growth-regulating compounds — that strengthen plant cell walls and activate the plant's own systemic defence responses. Healthier, more structurally robust plants are inherently more resilient against opportunistic pests and environmental stress events.

Ocean Magic's foliar application method is particularly effective for this purpose, as it allows the biostimulant compounds to be absorbed directly through the leaf surface where pest and pathogen entry points are most common.

Yes — Ocean Magic is formulated as a vegetative-stage complement to GreenPlanet's full nutrient ecosystem and integrates with base nutrients like Medi One or the Hydro Fuel system without compatibility issues. Its neutral N and P contribution makes it straightforward to add to most existing feed programs without disrupting your NPK targets.
