Bootstrap Farmer 6 cell tray inserts are made for the grower that wants an easily removable insert when growing a variety of crops. Made out of food safe heavy duty polypropylene plastic. These are not your typical throw away seed tray inserts. They are built to be used for many years of use.
- Extra strength 1.8mm thick PP (#5) BPA free black plastic
- 12 inserts fit per 1020 tray (Due to the tapering sides of the 1010 tray, 6 cell inserts do no fit correctly)
- Drain holes at bottom of seed propagation 6 cell trays
- Seed trays are guaranteed to last at least 2 years
- Each cell in tray insert is 1½"" x 1½"" on top which tapers down to 1"" at the bottom
- Seed tray insert outer dimensions: 5"" x 3⅓"" x 2¼"" height
These are not the flimsy ones, they are solid. I wish I would have bought more.
