Liquid pH Down is used to decrease pH in the nutrient mix. Consists of Phosphoric Acid.
Instructions: Add in small amounts of Liquid pH Down until the pH is reduced to the required level (5.5-6.5). The acid should always be added to the water and not the other way round, as acid splashes can be extremely painful.
Use in conjunction with a pH meter or good quality pH test kit.
Allow water to circulate for about 15 minutes before testing pH.
Liquid pH Down is highly concentrated and usually goes a long way for the average home gardener. Always test with small amounts at a time checking the PH level each time as well to see how much it was lowered. Add small increments at a time until you reach the desired PH level.
Extremely corrosive, avoid contact with skin and eyes. Do not ingest. Keep away from Children.
What is pH?
A measure of acidity or alkalinity of water soluble substances (pH stands for ‘potential of Hydrogen’). A pH value is a number from 1 to 14, with 7 as the middle (neutral) point. Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.
Acidity and alkalinity are extremely important factors in your crop’s water and root zone. A pH reading out of that range indicates conditions that very much decrease your plants’ ability to take in nutrients, grow well and produce large harvests.
