Mondi™, the original inventors behind the design, style, and performance of the patented Mini Greenhouse, introduces the latest innovation of the 4" Crystal Clear Mondi™ Mini Greenhouse - the ultimate humidity dome, engineered to deliver the highest propagation success rates. The 4" design offers a more compact space for seeds, cuttings, and young plants, and features the innovative Perfect Fit system for a secure fit with standard 1020 trays. Equipped with the Perfect 2-Finger Easy Vent, it allows for precise humidity regulation throughout the propagation process. Now manufactured using Avara Technology-a proprietary, food-grade material that is BPA-free, non-off-gassing, reusable, recyclable, and contains reclaimed ocean plastics-this dome sets a new benchmark in durability, safety, and environmental sustainability.
