The drainage plug holes keep the planter from leaking and makes it ideal for indoor use. Incase of overwatering, you can simply wheel the planter outdoor and open the plus for the extra water to drain and wheel it in again.
Perfect for year round gardening! Even during the heavy snow or storms, you can just wheel your garden indoors and grow your favorite green in winters and enjoy! The self watering planter keeps the plants well watered.
The moisture gauge tube helps you water the plants sufficiently and give you an understanding of how much water your plants need and lets you know when it's time to water them again. No more overwatering and killing your plants.
