GreenPlanet Medi One (4-3-3)
GreenPlanet Medi One (4-3-3) is a complete one-part liquid base nutrient designed to simplify plant nutrition from vegetative growth through flowering. Instead of combining several separate base fertilizers, Medi One provides macro, micro, and secondary nutrients in a single easy-to-use formula for growers who want a straightforward feeding program.
With a balanced 4-3-3 NPK analysis, Medi One supplies nitrogen, phosphorus, and potassium along with calcium, magnesium, sulfur, and essential micronutrients. Its formula incorporates organic-source ingredients, including hydrolyzed fish soluble extracts and mined potassium sulphate, to provide a broad nutritional foundation throughout the plant cycle.

Complete One-Part Plant Nutrition
One of the main advantages of GreenPlanet Medi One is its simplicity. Rather than requiring several separate base nutrient bottles, Medi One provides a balanced nutritional foundation in one liquid formula.
Its 4-3-3 NPK ratio supplies the three primary macronutrients plants require throughout their development. Nitrogen supports chlorophyll production and vegetative growth, phosphorus contributes to energy transfer and root and flower development, while potassium supports nutrient movement, water regulation, and several essential plant functions.
Calcium, magnesium, sulfur, and trace elements provide additional nutrition to complement the primary NPK profile.
Macro, Micro and Secondary Nutrients
Medi One offers more than nitrogen, phosphorus, and potassium. Its guaranteed analysis also includes:
- 0.95% calcium
- 0.6% magnesium
- 2% sulfur
- 0.01% boron
- 0.009% copper
- 0.08% iron
- 0.05% manganese
- 0.02% zinc
These secondary nutrients and micronutrients contribute to a broad and balanced feeding program throughout vegetative growth and flowering.
Formulated With Organic-Source Ingredients
GreenPlanet Medi One contains hydrolyzed fish soluble extracts that are processed to help preserve naturally occurring amino acids. These are combined with mined potassium sulphate to provide additional nitrogen, phosphorus, and potassium.
The organic components of Medi One are also designed to support microbial activity within the growing medium. An active root-zone environment can assist with the breakdown and cycling of organic materials, helping maintain nutrient availability around the roots.
One Formula From Vegetative Growth Through Flowering
Medi One is designed to serve as the primary base nutrient throughout the plant cycle.
During vegetative growth, its balanced nutrient profile provides the foundation needed for foliage, roots, and structural development. As plants transition into flowering, Medi One continues supplying essential macro, secondary, and micronutrients without requiring a separate bloom base fertilizer.
This makes it a convenient option for growers who prefer a simple one-part nutrient system instead of managing multiple base nutrient formulas.
Simple Application
GreenPlanet recommends shaking the bottle well before use.
Recommended application rate:
- 1–5 mL/L
- Approximately 4–19 mL/gal
- Apply twice per week
Adjust the concentration according to the plant’s stage of development and follow the current GreenPlanet Medi One Feed Program for stage-specific application rates. After preparing the nutrient solution, adjust the pH as required for your growing medium.
Designed for Soil and Soilless Growing Media
GreenPlanet Medi One is designed for use with:
- Soil
- Soilless growing media
- Coco-based media
- Indoor growing environments
- Outdoor cultivation
Its one-part liquid formulation makes it particularly convenient for growers who want to keep their feeding routine simple while maintaining a complete nutritional foundation throughout the crop cycle.
The Foundation of the Medi One Feed Program
Medi One can be used on its own as a complete base nutrient or as the foundation of the broader GreenPlanet Medi One Feed Program.
GreenPlanet’s full Medi One program combines the one-part base nutrient with complementary additives such as Ocean Magic, Massive Bloom Formulation, Rezin, and Liquid Weight. This gives growers the option of starting with a simple one-bottle base fertilizer and expanding their feeding program when desired.
For growers looking for a balanced and easy-to-manage nutrient program, GreenPlanet Medi One (4-3-3) offers a practical one-part solution for both vegetative growth and flowering.

Organic growing at it best !
Even though I grow with hydroponic nutrients in soilless mix, I use the Medi One when the plants seem a bit sluggish and they perk right up.
It makes my microgreens pop with even more green
