Ferro Osmosis Bloom A+B 5 liter - Standard Nutrient for Soil and Hydro

Ferro Osmosis Bloom A+B is a complete two-part plant nutrient for the entire flowering phase. Its composition is formulated for plants grown in soil or hydro systems using reverse osmosis or rainwater. This set contains 5 liters of Osmosis Bloom A and 5 liters of Osmosis Bloom B, providing a total of 10 liters of concentrated plant nutrient.

For reverse osmosis and rainwater

Ferro’s Osmosis nutrient range is formulated for source water with an EC of approximately 0.0. The separate A and B components jointly provide the primary nutrients and trace elements required by flowering plants. Always use both components in equal quantities throughout the entire flowering phase.

Directions for use

1. Shake both containers well before use.
2. Fill the nutrient tank to approximately 70% with reverse osmosis or rainwater. Ferro recommends a water temperature of 23 to 24 °C.
3. Add equal quantities of Osmosis Bloom A and Osmosis Bloom B and mix the nutrient solution thoroughly.
4. Top up the tank with water until the required volume and EC have been reached.
5. Check the pH and adjust it if necessary.

Ferro recommends an EC between 1.5 and 2.2 and a pH between 5.4 and 6.0. Apply the nutrient at every watering throughout the flowering phase and replace the nutrient solution at least twice a week.

Guideline dosage without pH and EC meters: 250 ml of Osmosis Bloom A and 250 ml of Osmosis Bloom B per 100 liters of water. Using pH and EC meters allows you to adjust the dosage more accurately to the plants and growing conditions.
