ORDER OF MIXING

Stock solutions:

Notes:

  • We recommend using the entire product at once to ensure optimal homogeneity and correct ingredient ratios.
  • Weighing water is more reliable than measuring it in litres
  • Wear protective gloves, dust mask and safety glasses when transferring the powder.

MAke sure your mixing vessel is 10% larger

than the volume of stock solution you intend to mix

For example making 1 litres of stock solution, you will need a 1,1 litres vessel.

Diagram showing that the mixing vessel should be 10% larger than the intended stock solution volume.

1

FILL THE MIXING VESSEL WITH THE REQUIRED AMOUNT OF WATER.

For best results use demineralised or reverse osmosis water at lukewarm temperature (~35 °C).

2

SLOWLY ADD THE ENTIRE BAG TO THE WATER AND MIX VIGOROUSLY FOR 1 MINUTE.

3

WAIT 24 HOURS TO STABILISE THE STOCK SOLUTION.

4

ALWAYS STIR STOCK SOLUTION WELL BEFORE USE.

  • Dissolve 1 bag of 1 kg in 10 litres of water. (other sizes > check mixing ratios tabel)
  • Make sure your mixing vessel is 10% larger than the volume of stock solution you intend to mix (For example making 10 litres of stock solution, you will need a 11 litres vessel).
  • Fill the mixing vessel with the required amount of water. For best results use demineralised or reverse osmosis water at lukewarm
  • Slowly add the entire bag to the water and mix vigorously for 1 minute.
  • Wait 24 hours to stabilise the stock solution.
  • Always stir stock solution well before use.

Example Dosage

Basic nutrient solution with stock solutions:

Vegetative nutrient solution EC 2,0 mS/cm

1L WATER

ADD 7.6 ml WSP-A

stock solution

MIX THOROUGHLY

ADD 7.6 ml WSP-B

stock solution

MIX THOROUGHLY

ADJUST pH

READY

  • Dose 7.6 ml of WSP-A stock solution to 1 litre of reverse osmosis or demineralised water.
  • Mix vigorously then dose 7.6 ml of WSP-B stock solution to the solution.
  • Mix vigorously
  • Adjust the pH if necessary.
  • The solution is now ready.

Generative nutrient solution EC 3,0 mS/cm

1L WATER

ADD 9.3 ml WSP-A

stock solution

MIX THOROUGHLY

ADD 8.7 ml WSP-B

stock solution

MIX THOROUGHLY

ADD 8.1 ml WSP-C

stock solution

MIX THoROUGHLY

ADJUST pH

READY

  • Dose 9.3 ml of WSP-A stock solution to 1 litre of reverse osmosis or demineralised water.
  • Mix vigorously then dose 8.7 ml of WSP-B stock solution to the solution.
  • Mix vigorously then dose 8.1 ml of WSP-C stock solution to the solution.
  • Mix vigorously
  • Adjust the pH if necessary.
  • The solution is now ready.

Timing

WSP-A & B are intended as an ingredient in horticultural fertigation of hydroponic nutrient solutions. Therefore, WSP-A & B should be used at any time a nutrient solution would be dosed. WSP-C is intended as flowering fertilizer in horticultural fertigation of hydroponic nutrient solutions in combination with WSP-A and WSP-B. Therefore, WSP-C can be used during generative phases of plant growth at any time a nutrient solution would be dosed.

Frequency

Frequency of use should be adapted to the crop type, environmental factors, phenological stage and water application rate (Litre of solution per cubic meter of irrigation flow). Check our website or scan the QR code for grow guides with more detailed and elaborate information. For irrigation frequency and volume, please follow the recommendation for the substrate and the respective irrigation system. Online information is great but never specific to your situation. Always consult with your Agricultural Advisor for your specific fertiliser situation.

Storage

Store in original packaging protected from direct sunlight in a dry, cool and well-ventilated area. Partly used or damaged containers should be closed well. Store between -10 °C and 45 °C (14 °F and 113 °F).

USAGE ESTIMATION

MINIMUM AMOUNT OF FEED WATER

Calculated based on an average EC of 2.8
Actual feed water may vary depending on EC level and growing conditions.

1kg

=    10L stock solution

≈    1.000L feed water

5kg

=    50L stock solution

≈    5.000L feed water

10kg

=    100L stock solution

≈    10.000L feed water

20kg

=    200L stock solution

≈    20.000L feed water
