Ask a Question
  • Hello - I would like to know exactly what kind of plastic these trays are made from? Are they polystyrene? Thank you.

    Our 72 Cell trays are made from polystyrene.  Our 1020 flats are made from polypropylene.

  • How many cubic inches of dry material will each cell hold?

    A little less than 3 cubic inches. The cells are 1 1/2 inches square at the top and 2 inches deep, they taper to 1 inch square at the bottom.

  • Does a/the depicted tool come with the starter trays ?? Also are there any other implements used for plant removal from each cell ?? Lastly, are there any starter trays for your 1010 no-holes trays? [Since I have at least 10 of your no-holes 1010 trays I just wanted to know if there may be a starter insert available for them or if the 1020 mesh may become available in 1010 for varied small scale micro greens growing.] Thanks.

    Here is what you can use for inserts on the 1010's: https://www.bootstrapfarmer.com/products/seed-trays-inserts-6-cell?_pos=1&_sid=6aaffcfe4&_ss=r    We also have 5x5's for small scale microgreens: https://www.bootstrapfarmer.com/products/5x5-grow-trays?_pos=1&_sid=ffb4992db&_ss=r    Regarding plant removal, we are working on plug poppers that will be out at the end of the year, but popsicle sticks, pencils or even just a gentle tug on the seedling will all work.

  • Is there an easier way to extract the plugs?

    You can use a tool called a widger dibber or a small stick/popsicle stick if you are having trouble pinching them out.  I find that extracting when the plugs are damp really helps too!

  • On the 72 seed starting trays how many are in a pack? I’m needing 410.

    You will want multiple 60 packs: https://www.bootstrapfarmer.com/collections/plug-trays

  • How many trays come in a pack?

    There is 1 tray per pack so a 5 pack is 5 trays.
