The rigid metal frame holds the paper pots open inside the nursery flat while you fill the paper chain pots with soil. After soil has been added the frame can be removed, with the soil holding the chain pots open. If your farm is doing a lot of transplanting, then you may want more than one frame to allow multiple people to fill flats.
The spreader frame is a REQUIRED component of the paper pot system. You can’t use the paper chain pots without this.
This item is a single spreader frame.
Our Paper Pot System Starter Kit includes 5 spreader frames, which may be a better choice for new paperpot users.
