T.A. pH Up
Premium pH management and silica source for hydroponics, coco and soil.
Control pH and boost silica levels at the same time
Whilst raising pH level may seem crazy to growers in hard water areas, it’s a real issue with very soft water or when using reverse osmosis. T.A. pH up allows that adjustment, and offers a good source of available silicate - which is often deficient in Hydroponics, due to its very low solubility. Proper silicate levels make a big contribution to plant health and so we include it in products whenever we can.
Importance of pH
To maximize plant growth, the pH level of your nutrients should be slightly acidic. Experienced growers consider the ideal pH for most crops to fall between 5.5 and 6.5.
Users of General Hydroponics nutrient products generally do not experience problems maintaining the proper pH range because the formulas are pH buffered. However, some important exceptions do exist. pH can acidify to an unacceptable level when nutrient solutions are used with poor quality water, or pH unstable media, such as rockwool. High growth rates can also destabilize pH.
How to use
To adjust pH: Add a small amount to water or nutritive solution as required. Mix solution thoroughly. Re-test with a pH meter or good quality pH test kit.
- Only a small amount of the product is needed as it is very concentrated.
- Always wear appropriate protection when handling strong alkalies.
- There is no such thing as an ideal pH. High values help cation uptake and low values help anion uptake: every fixed pH is a compromise. The usual safe range recommendation is from 5.5 to 6.5. Our advice is to stay on the low side: from 5.5 to 6.2.
