Ask a Question
  • how many trays are in a pack?

    We have 1, 5, 10, 25 and 60 packs available.  There is a drop down to the left of the "add to cart" button with the different sizes available with prices of each pack below.

  • Does the drainage flat sit in the solid flat so it is directly on the bottom (rather than being slightly suspended as some do), and/or vice versa? Also, will you have 128's in stock soon? Thanks!

    Our trays are suspended off the bottom of the drainage flat.  We find this advantageous since it allows your roots to get more oxygen and your roots will stretch down toward the water as they become more developed.  However we currently are in the process of creating a micro green flat tray that is shorter than our existing flat which would allow for the cells to sit directly on the bottom.

    Regarding out 128 Cell trays we should have more available the first week in March.

    Thanks for reaching out!
