10 irrigation devices and identification cards. The single character identification cards are made of PVC, waterproof, inserted directly into the flower pot to identify the plant name or usage time. Plant watering is made of clay, and due to its characteristics it is a little fragile. The nails with clay automatically release water. The thinner the ground 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 place the watering pile in 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 to ensure better release action. The more piles in the ground, the more water the soil can absorb. Note: For heavier bottles, you need to insert almost the entire stake into the ground to prevent the stake from breaking. The package contains 10 watering columns (bottles not included). You can choose used wine bottles or plastic bottles with long necks to be compatible with wooden posts. Watering your nails is the perfect tool to recycle used bottles while freeing up your work. Slow watering posts are used for vacations and business trips. There is no standard triggering time for spikes. Normally 1 liter of water can be watered automatically 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 while on vacation or traveling and to ensure the water needs of the plants.
