Constructed with durable materials and engineered to stand up to harsh conditions, the cold frame is an economic option for stress-free overwintering.
For growers looking to keep their crops safe, especially during the overwintering process as cold temperatures are in season. The Coldframe also doubles as a shade structure and can be heated to create a warmer climate, depending on your growing needs.


The Coldframe Greenhouse is perfect for nurseries and entry-level growers looking for a more budget-friendly greenhouse option.
Cold frames are designed for the winter coverage of potted nursery stock. Cold frame greenhouses are not intended to be heated nor do they have any means of ventilation. The frame consists of galvanized steel mechanical tubing for strength and longevity. The endwalls and baseboards are treated lumber provided by the owner. The frame is covered with a single layer of 4 - 6mil white polyethylene greenhouse film.
