It Is A Necessary Tool for Indoor and Outdoor Potted Plants. It Is An Ideal Tool for Home Gardening, Farmland Planting, Garden Care and Professional Garden Design. The Significance of Soil Ph for Plants: Soil Ph Directly Affects The Efficiency of Nutrient Uptake By Plants. Different Plants Have Specific Soil Ph Needs (E.g. Neutral Soil for Vegetables, Acidic Soil for Blueberries, Etc.), and Unsuitable Ph Can Lead To Stagnant Growth or Death. Significance of Soil Moisture for Plants: Proper Moisture Helps Plants Absorb Water and Nutrients. Too Much Dryness Can Lead To Dehydration and Wilting of The Plant, and Too Much Wetness Can Lead To Lack of Oxygen and Rotting of The Roots. 1. PH measurement range: PH: 3-8 2.
