PH Up
There is no perfect pH. Higher values facilitate cation absorption and lower values help anion absorption : each pH level has compromises. The safest recommended average value is 5.5 to 6.5. Our advice is to stay in the lower part : 5.5 to 6.2.
Aquatic Earth pH+ :
Premium pH control and silica source for hydroponics, coconut and soil.
Controls pH and raises silica levels at the same time
While raising the pH seems absurd for growers in areas with hard water, it is a real problem with very fresh water or reverse osmosis. Terra Aquatica pH+ allows you this adaptation, and offers you an excellent source of Silicate - which is often missing in hydroponics because of its very low solubility. Adequate levels of silicate make a great contribution to the health of the plant and therefore we include it in products when we can.
Use:
CAUTION : Always wear appropriate protections when handling strong acids/alkalis.
pH+/- :
Add to the water or nutrient solution as needed. Re-test the pH and correct it if necessary.
