10 Irrigation Equipment and Identification Cards . The single-character identification cards are made of PVC, waterproof, directly inserted into the flower pot to identify the plant name or time of use. The plant waterer is made of clay, and due to its characteristics, it is a little fragile. The nails with clay automatically release water. The thinner the spike, the faster the drainage. Easy to use with long-necked wine bottles or plastic bottles. First dig a hole in the ground. Secondly, carefully lay the pouring pile into the soil. Fill the bottle or wine bottle with water, connect the bottle to a stake and turn it upside down. Insert 7/8 stakes into the ground for better release effect. The more heaps in the ground, the more water the soil can hold. Note: For heavier bottles, you need to put almost the entire stake into the ground to prevent the stake from breaking. The package includes 10 watering columns (bottles not included). You can choose used wine bottles or long neck plastic bottles to be compatible with wooden stakes. Watering your nails is the perfect tool to recycle used bottles while freeing up your work. Slow watering posts are used for vacation and business trips. There is no standard trigger time for spikes. Normally 1 liter of water can be automatically watered for about 7-10 days. The release rate of plant watering depends on the size of the pot, soil composition, plant needs and climate. The main purpose is to prevent the owner of the flower pot from overwatering on vacation or when traveling and ensure the water needs of the plants.
