Drip Irrigation System: Self watering spikes for outdoor and indoor use. Plant Watering Devices: The tube end of automatic watering spikes has been sharpened, so just need to fill the container and then insert it into the soil for automatic watering. Upgrade Plant Waterer: Send the water directly to the mouth of the plant, which can last for a month. Even if you forget to water or travel, you don't have to worry about the plants drying up Application: "Irrigation Spikes" perfect for vegetables, potted plants, houseplants, water plants, patio plants, hanging baskets, desk pots, hanging plants and many more. Note: Both the water outlet and the water inlet are small holes at the bottom, so irrigation requires patience, and some soils with too dense soil will seep slowly.
