Application

Apply appropriately
10 g per 10 litres of water; stir well.
- Base solution
- 10 g per 10 litres of water; stir well.
- Measuring
- Two level capfuls equal 10 g according to the front label. Weigh for accurate quantities.
- EC figure
- Label: +1.6 mS/cm at 25 °C. This is not a universal target EC for every starting water.
- Aerated Aqua36 tray
- Only for the Aqua36 tray with the optional aeration system: 10 g starter fertiliser in 12 litres of water, no higher than the maximum mark. The system instructions state approximately 1.3 mS/cm, taking the existing water values into account; measure the actual EC.
- 1 L water (base solution)
- 1 g fertiliser
- 10 L water (base solution)
- 10 g fertiliser
- 30 L water (base solution)
- 30 g fertiliser
-
Have system instructions ready
Follow the Aqua 36 system instructions for crop and water level.
-
Measure water
Measure the required water volume in a clean vessel.
-
Weigh fertiliser
For the base solution, weigh 1 g fertiliser per litre of water; 10 litres require 10 g. For the aerated Aqua36 tray containing 12 litres of water, follow the special case above: 10 g starter fertiliser and a check of the actual EC.
-
Stir in
Add the fertiliser to the water and stir well.
-
Check solution
Check the mixture before use; interpret EC figures together with the starting water and system instructions.
-
Supply the system
Use the prepared nutrient solution according to the Aqua 36 system instructions.
The older 3000 l yield in the system instructions is corrected: 300 g makes 300 l of nutrient solution at 1 g/l.

Which quantity or programme should I choose?
Two level capfuls equal 10 g according to the front label. Weigh for accurate quantities. Label: +1.6 mS/cm at 25 °C. This is not a universal target EC for every starting water.
What is the starter dose for the aerated Aqua36 tray with 12 litres?
Special case in the Aqua36 system instructions: When using the optional aeration system, the Aqua36 tray may be filled to its maximum mark with approximately 12 litres of water. For this initial fill, the instructions specify 10 g starter fertiliser in 12 litres of water and an EC value of approximately 1.3 mS/cm, adjusted up or down for the existing water values. Check the actual EC with a suitable meter. This applies to the aerated Aqua36 tray, not to other containers in general.
