Checking the pH of your media can make a big difference to a grow as elements absorb differently at different levels. While there is no pH where every one absorbs at maximum efficiency, it is around pH 6.0 that offers the best trade off. Measuring acidity in a hydroponic water tank is easy with a pH meter, but how can you find the pH of soil and coco? That’s where the Soil pH Meter comes in!
Simply push the probe from the Soil pH Meter into wet soil, wait 2 minutes and the needle will move to indicate acidity or alkalinity. The range on the meter is between 3.5 and 9.0 which should easily cover the vast majority of soils. With this information, you can adjust the pH of nutrient solutions that you feed you plants. You can always add mixers to the media to alter the pH too – peat or sulphate of ammonia to lower ph and lime to raise it.
The Soil pH Meter is very useful if you are planning on a bit of outside gardening too. There are many plants that prefer one type of soil over another and choosing the right ones for your soil can make things much easier! Included with the meter is a list of over 400 pH preferences for various plant that will help you select the best plants.
Acid soil plants – Heathers, rhododendrons, azaleas, camelias, potatoes, tomatoes and strawberries.
Alkali soil plants – Forsythia, chrysanthemum, delphinium, firethorn, brussell sprouts, cabbage, onions and cauliflower.
