Mondi Mini Greenhouse's 'perfect fit' system was developed to fit tightly on standard 1020 trays. The Mondi Mini Greenhouse has the most volume of space, allowing seeds, cuttings and plants more room to develop. The Mondi 'Perfect 2 Finger Easy Vent' allows for perfect control of humidity levels for optimal environmental conditions. Thick, heavy duty, high grade plastic maximizes light penetration and stands up to repeated use. The Mondi Mini Greenhouse gives seeds and cuttings the Mondi Advantage.
