If you accidently dropped the plant or seed into your system don't worry, we have the solution for this.
First, turn off your system and move out any plants that will be in the way of the bottom pods.
You can then use a drain snake to reach in and grab the plant that fell in. We provide these online as well as you can purchase them from local hardware stores.
If you cannot reach the pod you can also shred up the pods using the drain clog remover tool.
If you cannot reach it, try cleaning out the system (plant pods removed) with hot water and hydrogen peroxide in hopes it comes out of the drain.
