✅ ALL-IN-ONE MINI KIT: This kit includes a 1-inch deep mesh tray, a 1-inch deep no-holed tray, a 2.25-inch deep no-holed reservoir tray, and one sheet of our Silicone Reusable Grow Medium (large sprouting tray size). Together, they create a compact, easy-to-use Kratky system—perfect for growing microgreens at home, in small spaces, apartments, or on your kitchen counter.
💧 HYDROPONIC GROWING MADE SIMPLE: The Kratky method, created by Dr. Bernard Kratky, is a no-pump, no-electricity hydroponic system where plants sit above a nutrient-rich water reservoir. This miniature version works the same way as our full-size kit but in a smaller footprint, making it ideal for quick, low-maintenance grows.
✨ WORRY-FREE WATERING: The 2.25-inch deep tray holds enough nutrient solution to feed your microgreens for several days, depending on the crop. Once roots reach the water, they naturally absorb it—so even if you step away for a day or two, your greens stay hydrated without an automated system.
🌱 EASY TO START: Simply assemble the trays, add the reusable grow medium, seed your microgreens, and guide them through germination. Fill the reservoir, place under light, and watch your mini hydroponic garden flourish. Periodically check water levels and ensure roots stay in contact with the nutrient solution.

✅ Crafted with care from thick & Durable BPA Free PP (Polypropylene) plastic and comes with Silicone Mesh Sheets to allow for use with small seeds, such as broccoli, without using coco coir or soil.
