(National new practical patent. Special watering indicator for plants such as flowers, vegetables, fruit trees, etc.) The water measuring pen is a tool for measuring soil moisture. It senses the level of humidity by measuring the water absorption of the soil. All kinds of plants have their suitable soil water absorption growth range. For example, cucumbers need to be watered when the water absorption of the soil exceeds 20 kilopascals (Kpa). The attached table lists the upper limit of soil water absorption capacity of some plants. Above this value, for the plant, the soil moisture is insufficient and irrigation is needed, otherwise it will grow poorly and reduce production.
HDPE bottles offer stronger tensile strength than LDPE containers, are harder and more opaque, and can withstand somewhat higher temperatures: 120°C (248°F) for short periods, 110°C (230°F) for longer periods. High-density polyethylene cannot withstand autoclaving. HDPE (high density polyethylene) plastic bottles offer a mildly stiff impact resistant bottle, with a great moisture barrier. The HDPE plastic bottles are offered in a great range of sizes, shapes and color.Choose between flip tops, pumps, atomizers or standard lids.
