Lusterleaf Rapitest 1845 Digital Soil pH Meter
Plants need the correct pH level which controls how well they utilize the nutrients available in your soil. The Rapitest Digital pH Meter allows you to instantly determine how acidic or alkaline your soil is. 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 will determine its condition. You will be able to adjust the soil more effectively and economically. Includes a handy plant care booklet listing the preferences for over 400 plants. Not only for using outdoors but for potted plants (and houseplants) as well.
