Metal frame for holding open paper chain pots for filling with potting soil and seeding. This is a required component of the paper chain pot transplanting system and is included in the Paper Chain Pot Opening Kit. Some farms, especially larger farms, find they may want additional frames if they have work crews seeding large numbers of flats at one time because the frames need to stay in place while using a dibble or seeder. For many small farms, the 1 frame included in the Opening Kit will suffice.
