Open the CIPO recordAbstract From the Canadian patent
Molded strips of temporary planting pods are stacked together with growth barrier film between adjacent strips to provide compact package for seed germination or seedling growth. The film confines root growth to the strip in which the growth starts and narrow interconnections between the pods of a strip limit the growth of roots from one pod toward the next pod. After seeding and initial watering the stacked assembly can have additional water supplied from its bottom to encourage root growth toward that bottom. When planting, the individual parts can be readily broken or cut off and separately planted. Abstract of the Disclosure
