Extremely accurate, the Rapitest Digital pH Meter allows you to instantly determine how acidic or alkaline your soil is. Plants need the correct pH level which controls how well they utilize the nutrients available in your soil.
All plants have a pH preference, so it is important to know what this measurement is. You can choose plants with the same preferences, avoid those that will not do well in your soil, or know how to go about supplying their special growing needs.
By testing your soil, you determine its condition so that you can adjust it more effectively and economically. Includes a handy plant care booklet listing the preferences for over 400 plants. Use indoors for potted plants, too!
