The Plantaform Pod Plugs are essential accessories for your Plantaform Indoor Garden, designed to serve two primary functions. First, they are used during the Rejuvenate cleaning cycle to cover all 15 open pod holes, ensuring the system is properly sealed during maintenance. Second, when harvesting plants, especially if you harvest them one at a time, the Pod Plugs help maintain optimal airflow and fog levels by covering the empty pod holes. This ensures a balanced environment for the remaining plants, allowing them to continue growing and thriving in ideal conditions.
