Working principle: Refer to the siphon principle. Fill the device with water, tighten the lid, and insert it into the soil to form a vacuum. As the soil dries, water droplets will slowly precipitate from the ceramic end of the irrigation device, gradually moisturizing the surrounding soil. .Durable material: The automatic irrigation kit is made of plastic and ceramic with good permeability. It is environmentally friendly and non-toxic. You can use it safely for a long time to make plants healthier, live longer, and make your life easier. .How to use: First, remove the lid and immerse the ceramic end in a water container for 15 minutes. Second, fill the interior of the irrigation equipment with water and tighten the lid. Finally, insert the irrigation device into the flower pot, and put the plastic tube into the water container. .Precautions: On the one hand, the inside of the equipment must be filled with water and the bottle cap must be tightened so that the equipment can form a vacuum state. On the other hand, the sink and flower pot must be kept at least at the same level. The high trough can speed up the drip irrigation process. .Scope of application: The drip irrigation kit is very suitable for indoor and outdoor plants, whether it is office plants, flowers, or potted plants, and vegetables. It is a practical solution for weekends and short holidays. This is an exquisite gift for plant lovers. .
