The Stewart Medium Unheated Propagator is a reliable, high-quality solution designed to create a stable microclimate for young plants without using electricity.

Equipped with adjustable ventilation dials, it allows you to easily regulate humidity and airflow to ensure your plants thrive without damping off. Its compact footprint makes it a perfect fit for home growers, allotment planners, and hobbyists working with limited space.
