GreenPlanet Nutrients 1-Part Medi One

Yes — Medi One is a complete, full-cycle base nutrient. Its balanced macro and micronutrient profile is formulated to support vigorous vegetative growth and then transition directly into the flowering stage without any formula change. The 4–3–3 NPK ratio provides appropriate nitrogen levels for leafy vegetative development while the phosphorus and potassium support resinous floral production.

For growers who want to layer in additives at specific stages, Medi One is the base for GreenPlanet's official Medi One Feed Program, which provides guidance on supplementing with targeted products at key points in the growth cycle.

Medi One has a scalable application range of 1–5 ml/L (4–19 ml/Gal), applied twice per week. The wide range allows you to adjust feeding strength based on plant size, growth stage, and medium type — starting lighter during early vegetative growth and increasing toward the higher end of the range as plants mature into full flower production.

Always shake the bottle well before measuring, add to your water, adjust pH to the desired level, and apply twice weekly throughout the growth cycle.

Hydrolyzed fish soluble extracts provide nitrogen alongside a naturally occurring amino acid profile — something synthetic nitrogen sources don't deliver. GreenPlanet slow-steams their fish extracts specifically to preserve these amino acids, which serve as direct building blocks for plant proteins and support microbial activity in the root zone.

This approach aligns with the formula's organic certification goals and contributes to the increased microbial life that helps break down organic particles in the medium into plant-available nutrients.

OMRI (Organic Materials Review Institute) listing means the product has been independently reviewed and approved for use in certified organic production in the USA. For medical growers, this certification provides assurance that Medi One's ingredients meet strict standards for natural sourcing and purity — with no synthetic additives or prohibited substances.

Combined with CFIA Exempt status in Canada, Medi One carries dual independent certifications that make it one of the most compliance-verified base nutrients available for organic and medical cultivation programs.

Medi One is formulated as a versatile base nutrient that can be used across soil, coco coir, and other grow media. Its organic, fish-based formulation is particularly well-suited to living soil and amended substrate environments where its microbial-stimulating properties can be fully expressed.

For recirculating hydroponic systems, the organic particulate nature of the formula requires additional consideration — reservoirs should be monitored closely for buildup and potential microbial activity in the solution itself. Consult GreenPlanet's feed chart for system-specific guidance.

Yes — Medi One is the foundation of GreenPlanet's dedicated Medi One Feed Program, which is designed to work in combination with GreenPlanet's full range of supplements and bloom additives. Products like GreenPlanet Nutrients Massive Bloom Formulation, GreenPlanet Nutrients Liquid Weight, and the Rezin Terpene Enhancer can be layered in at appropriate stages according to the official feed chart.

Always refer to the Medi One Feed Program chart for recommended stacking ratios and timing to avoid overfeeding and ensure each product's contribution is properly accounted for in your overall PPM target.

Because Medi One is formulated with organic, naturally derived ingredients — including fish soluble extracts — the heavier components can settle at the bottom of the bottle between uses. Shaking well before each application ensures the formula is fully homogenized and that every dose reflects the correct nutrient ratios listed on the guaranteed analysis.

Skipping this step could result in inconsistent feeding — with early pours being lighter and later pours being more concentrated than intended.
