Our refill sets are designed to be used with our microgreen starter kits and base grow kits. Each set will help take the guess work out of continuing growing your microgreens.  Each set contains pre-measured seed packs and enough organic coco coir to grow them all.  Seed weights are either pre-measured for growing in our 10 x 10 propagation trays or our starter grow kit trays; click on each refill set for specific details.
