    Ask a Question
    • What is the measurement at the base of the tray cups. I have another brand 2.5" pot (for resale purposes), and it doesn't fit down in the tray 😔

      They are about 1 3/4" on the bottom.

    • 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

    • Will these fit into the bottom trays from jiffy or burpee? I have several of those in fine shape still that I would love to buy sturdy cell packs for!

      We cannot guarantee our trays will fit other brands, as ours are designed to specifically fit with our product line. I recommend checking out the product dimensions on the product page and comparing those to your trays.

    • One pack contains how many trays?

      A one pack has one tray, a 5 pack has 5 trays, etc.
