All of the order size options depend on your intake. These can be added to everything from smoothies to pizza. If you are new to micro greens, we recommend starting with a 10"x10" box of four flavors first. Doing this will enable you to both try a variety and gauge intake from week to week. A full tray is 10"x20" and if ordered 8 days prior, you will receive a tray that has been planted just for you. This is ideal for families that eat microgreens for their nutrition in many dishes. Just cut when you are ready to use, the rest will continue to grow. The below pictured is a 10"x10" with different varieties. The small package is a 5"x 5"sample box used for samples. They are grown in organic hemp or bamboo pads and when purchased they remain in the grow medium ready to cut as you use.
