Prepare a water containers filled with water (a narrow bottle, such as mineral water bottles). 3. Make sure the pottery pieces filled with water, because the green plastic cover tightly with the pottery pieces. 4. Stick cone piece a little bit into the soil of plant. 5. Then it will automatically bring water into the other end of the container, to the plants. Tips: 1. In order to watering better, put the bottle watering device level below the high end of the green plastic cover. 2. Please Note the demand of each plants and pots size,and uses the appropriate pieces of watering devices. 3. If failure to water your plants, please repeat the above operation steps. 4. After months of using, the ceramic piece parts need to be cleaned so as not to affect the effect of continue-using. Issues you may have: 1. Too much water. Move the water bottle/jug a bit lower in height relative to the cone part. This will increase resistance and slow the flow. 2. Not working at all. You did not (a) fully submerge both pieces in water like in above steps or (b) the end of the tube is not low enough in the water jug. you cannot just stick it in the top or it will not work. 3. Probe waters too much. Just remove cone from soil and stick only the tip into the soil. This will reduce the flow of water drawn from the probe. 4. Probe does not water at all. You did not (a) fully submerge both pieces in water like in above steps, or (b) the end of the tube is not deep enough in water.
