Non-chain paper pots are like growing in soil blocks but without the time, hassle, and expense of making soil blocks. The paper pots easily pull apart when it is time to plant. The paper can go into the ground where it will decompose or it can be discarded. Using the non-chain paper pots requires the same durable bottom tray as the paper chain pots (these pots will not fit in a standard 1020 tray). The pots are held open using simple plastic clips (sold separately). 50 count cells are 6.5cm x 5cm deep (approximately 2.5 inches square by 2 inches deep).
