Sarosora Planter with Coir & Foam Stone

For your flowers, herbs or succulents, these self-watering pots are a great purchase. They include 6 quarts of coconut coir soil and foam stone. The self-watering system features an indicator that allows you to observe the water level at any time. If the water level is below or close to the minimum level, use the special water injection port to easily add more.

“This product is a life saver (at least to my plants),” says an Amazon reviewer. “I sometimes forgot to water my plants due to a busy work schedule and because of this my plants suffer from it. But this product can hold water up to about a week. But what I like most about this is the water injection. You can water your plants from a port where the water will go straight into the soil and not on top. I notice that when I water my plants, little flies always appear! But it hasn’t happen with this pot so I highly recommend.”
