Ask a Question
  • Are the packs 60 trays or 60 cells?

    60, 6 cell inserts. 

  • How do you clean and disinfect for reuse?

    Use a hose to wash off any soil residue. They can then be washed in hot soapy water. For further disinfecting they can be dipped either into vinegar, 3% hydrogen peroxide, or a mild bleach solution.

  • What is the diameter of the drainage hole on a cell?

    The 6 cell plug tray inserts have slits that are about 1/8". Over the next 3 months, we will be redesigning them to have 5/8" hole on the bottom.

  • What can be used to push seedlings out of the holes at the bottom of these cells?

    Our Widger Dibber is the best tool for removing seedlings from cell trays! Here is the link to the product!https://www.bootstrapfarmer.com/products/widger-dibber-set?_pos=2&_sid=426392a8a&_ss=rhttps://www.bootstrapfarmer.com/products/widger-dibber-set?_pos=2&_sid=426392a8a&_ss=r

  • How many 6 cell inserts fit in the 1020 tray.

    12 of the 6 cell inserts fit in each 1020 tray.

  • Will these 6 cell trays fit in the 5x5 tray with humidity dome?

    They won't fit in the 5x5 trays.  They are designed to fit within the 1020 trays.

  • Will 12 of these 6-cell inserts fit into the 1010 seed starting flats?

    You can fit 6 of the 6 cell trays in a 1010.  However they won't sit completely flat.  They are better designed for 1020 trays.
