Nutrient instructions 1Kg
- Obtain 2 containers of at least x 2.5 litres. Ensure the containers are clean. Label one as A, and one as B. Fill the containers 2/3 full with water – using warm water will speed the process of dissolving the sales.
- Add the nutrients from bag A to the container marked A. Stir until dissolved. Add extra water to make up to 2.5 litres.
- Add the nutrients from the larger bag B to the container marked B. Stir until dissolved. Add extra water to make up to 2.5 litres. Repeat for the smaller B Mix well.
You will now have 2 containers of “stock” nutrient solution. To use these, add equal measures of A and B to the water. Never mix the stock nutrient in concentrated form.
The nutrient solution should be refreshed every 3 weeks in a Hydroponic system.
The amount of nutrient required depends on the feeding requirements of the plant.
For Low feeders such as lettuce and watercress, add 3ml/L of both A and B. This will result in a cF of approximately 14 (ec 1.4)
For medium feeders such as zucchini, capsicum or mixed crops, add 5ml/L of both A and B. This will result in a cF of approximately 22 (ec 2.2)
For medium feeders such as tomatoes or beans, add 7ml/L of both A and B. This will result in a cF of approximately 32 (ec 3.2)
- Do not spit the A and B bags into smaller quantities as this will potentially unbalance the nutrient formula.
- Never mix solution A and solution B together directly
- The pH of the nutrient mix is approximately 6. This will vary depending on the quality and pH of the water used when disolving the mixture. The importance of pH is discussed in the link optimal PH for growing
