Collection: Mini Greenhouses/Cold Frames

Mini greenhouses and cold frames offer compact protection for seed starting, hardening off transplants, overwintering suitable plants, and extending production into cooler parts of the year. Because these small structures have limited air volume, they can heat and cool quickly as conditions change.

Choosing and using a compact structure

• Confirm the interior height and growing area for the plants and containers you expect to use.
• Place the structure where it receives appropriate seasonal light and can be anchored securely.
• Vent on warm or sunny days and monitor temperature and moisture regularly.
• Check the covering material, access panels, anchoring method, and replacement-part availability.

For larger structures, visit Greenhouses. You can also shop Frost Protection for temporary coverings or Greenhouse Accessories for compatible hardware and monitoring tools.
