Tray Insert - 12 Cell Trays

12 plastic cell trays are ideal for growing personal and perfectly sized portions of microgreens and wheatgrass because they are much smaller than an entire 20x10 or 10x10 tray. Plastic 12 cell 5x2 trays are perfect for seed starting for much larger crops such as artichoke, borage, and especially onions. 2x5 plastic trays are ideal for growing your own onion starts for seasonal transplanting. When seeded densely, just one 2x5 plastic tray can easily germinate up to 30 onion starts for transplanting. 12 cell 2x5 inch plastic trays offer gardeners and microgreens more options and sizes to cater to your growing needs. If looking to experiment with new microgreens seed varieties, try growing in a small 2x5 to more easily manage the results without having to waste unnecessary seed.
