Description: MOISTURE, PH, SUNLIGHT IN ONE: Test soil moisture, pH value and sunlight by one single meter. Quickly helps you to know when you need to water your plants. Control the pH value in the soil and know whether the plants are getting adequate sunlight. FASTER MORE ACCURATE READING: The premium double-needle design supports the accurate and reliable measurement of soil moisture and pH acidity. EASY TO USE: No batteries needed. Easily switch back and forth between moisture, pH, and sunlight position. Insert the sensor probes into the soil about 2-4 inches, adjust position of probe until pointer swings, and read the value. Clean the probe after each use. WIDE MEASUREMENT RANGE: Moisture Range: 1-10 (1-3 Dry , 4-7 Normal, 8-10 Wet), Relative Light: 0-2000lux (0-200 Low, 200-500 Low+, 500-1000 Normal, 1000-2000 High), pH Range: 3.5-8ph (3.5-6.5 Acid, 7-8 Alkaline) INDOOR OUTDOOR USE: Design to be light and portable and easy to carry around for outdoor use. Having Green Thumb Troubles? Have you ever been disappointed with the performance of your vegetables, potted plants or flowers? The pH level may be the problem. Plant roots absorb minerals such as nitrogen and iron only when they are dissolved in water. Now if this soil composition (mixture of water and nutrients within the soil) is too acidic or alkaline, some nutrients won't be dissolved, and as a result, they won't be available to plants. If the pH isn't close to what plants require, some nutrients, such as phosphorus, calcium and magnesium, can't be dissolved in water. And since plants drink their food instead of eating it, if the nutrients aren't dissolved first, the plant can't absorb them. Thus, your plants, flowers vegetables and garden won't grow or produce to their full potential. Most nutrients that plants need are readily available when the pH of the soil solution ranges from 6.0 to 7.5. Below a pH of 6.0 (acid): Some nutrients such as nitrogen, phosphorus, and potassium are less available. Above a pH of 7.5 (very alkaline): Iron, manganese, and phosphorus are less available. Please check pH level recommendations for your types of plants. Assists in Growing Healthy Plants Flowers 3 in 1 meter will assist in growing healthy plants and vegetables. It works well in vegetable gardens, flower gardens, lawns and potted plants. The best way to ensure your plants reach their full potential is by determining if you have the proper soil conditions. The pH Meter not only indicates the amount of alkalinity or acidity in the soil, but it also measures moisture content and light amounts. pH Meter The pH meter will measure acidic or alkaline soil conditions with its pH level meter. Moisture Content Meter To ensure you have the correct moisture content to avoid over or under watering, utilize the Moisture Content Meter. Light Amount Meter Plants and flowers need the correct amount of light. This meter as the ability to measure light amount. Compatibility: Plants, flowers, vegetable gardens, potted plants and lawns. Package Includes: 1 X 3 in 1 meter
