We choose cork stoppers with lids to keep them moist. Therefore, we recommend that you cover the corks after spraying water. Fog and water droplets indicate that the humidity is sufficient, and there is no need to excessively increase the moisture. At this time, please place the glass bottle in astigmatism (not in direct sunlight). PS: If the color of the moss becomes dark green, it means that there is too much water. At this time, you can open the cork to ventilate and increase the sunlight. In addition, if other small grass grows in the bottle, you can also use tweezers to remove it.
