Our Outsunny portable greenhouse utilizes lightweight yet sturdy PE coverings built over a powder-coated steel frame. Combining these two elements is an incredibly durable plant nursery that can be moved from location to location, fitting in tight spaces as available. The three zipper doors of the hot house allow for easy access and ventilation, or it can be sealed to maintain the internal climate. This makes the plant greenhouse perfect if you want to reduce excessive heat or cold and keep your seedlings secure throughout the seasons.
