Uses:Preferred for seed starting of early planting annuals and vegetables. For seedlings needing more days in the greenhouse before transplanting such as eggplant, peppers and tomatoes. Also great for step up transplants to larger planting containers or direct transplants to ground post frost.
Commercially proven in step up to soilless bag cultures.
Shelf life:Once planted, the #4 square stays intact for up to 3 months in a greenhouse setting. If not planted and kept in a cool dry location, shelf life is indefinite (a dry location is critical).
