7G
Dip the test a second-stems in water, then shake to knock off the remaining droplets.
Leave on for a minute and see the color scale to read the result.
Store at a temperature below 30 °. Close the bag immediately after use.

Preparation of irrigation water: The hardness of the water partial carbonate causes spots independent
sirables on the leaves and continuously increases the pH value to the roots. When the pH exceeds
Of 10 °, we recommend for the welfare of your plants decarbonation. The latter becomes
necessary when the pH is greater than 15 °. A hardness of 10 ° = 178 mg CaCO 3 / liter of water.
Decarbonation, softening: Transformation of gypsum calcium carbonate. The salt content
Total not declining. Possible use to a hardness of 15 °.
Preparation: Dilute 10 cm3 of concentrated sulfuric acid per m3 of water per degree. As a
safety, let a hardness of 3 to 5 ° in water. Each acid intake, mix water for 30
min. and monitor the pH value.
Range of pH values set: 4.0 to 4.5. Use a basin acid-resistant.
Deacidification: Caustic potash carbonate required to neutralize an acid is very water
made from hydrated lime Ca (OH) 2.
Preparation: Hydrated lime 40g / 20 liters of water. 20 liters of caustic potash carbonate / 1m3 of water.
Mix the water for about 30 min.
Limit value for crops: Use rain water!
Highly sensitive crops: 5 to 8 ° d / KH = 90 to 140 mg CaCO3 / liter of water
Potted plants: 8 to 12 ° d / KH = 140 to 210 mg CaCO3 / liter of water
Beds: 10 - 15 ° / KH = 180 to 270 mg CaCO3 / liter of water
