Meet John — Helping Gardeners Grow Better

Over 20 years ago, John started gardening to grow better food for his family, but quickly realized most greenhouses weren't built to handle real weather. Growing up in Lithuania, he began building stronger, longer-lasting greenhouses based on real hands-on experience, and today Dear John Greenhouses helps gardeners around the world grow with confidence.

Every Dear John greenhouse is designed with long-term durability and real growing experience in mind. Manufactured in our factory in Lithuania, EU — where winters are harsh, winds are strong, and weather conditions can change quickly — our greenhouses are built using heavy-duty galvanized steel frames with a powder-coated finish and thick UV-protected polycarbonate panels for maximum strength and insulation.

We focus on quality materials, careful manufacturing, strong weather resistance, and practical design details that help the greenhouse perform reliably through heavy snow, strong winds, extreme temperatures, and everyday growing conditions.
