    QUESTIONS & ANSWERS

    Ask a Question
    • If I don't need the entire brick at one time, can I cut off how much I need before hydrating, or hydrate the entire brick and store the leftover loose product (after letting it fully air dry, I assume)? If the latter, for how long in what container can I store it?

      The easiest thing to do is either cut off a piece of the coco brick or just hydrate a potion of it and tear off what you need.

    • Are these bricks 1/3 cu ft before or after they are hydrated?

      The coco coir expands to 1/3 cubic foot after hydration. 

    • can the material be reused on several crops over time?

      We do not recommend reusing growing medium because it can contaminate future microgreen trays. You can find our recommendations for what to do with spent trays here: https://www.bootstrapfarmer.com/blogs/microgreens/reusing-spent-microgreen-trays

    Coco coir brick

    This is my second round of this product from Bootstrap. I love these bricks. I use them to make my own seed starting mix.

    EXCELLENT COCO COIR!

    This is some excellent coco coir. I even forgot to wash it and my microgreens still flourished. Almost tempted to make this my permanent seedling starter!
