The cold frame attachment is suitable for all Fleur De Lis Living raised beds with a shelf and is color-coordinated with the "Klara" raised bed, No. 1840. In just a few steps, your Fleur De Lis Living raised bed can be turned into a cold frame that is perfect for growing young plants: The 4mm -thick hollow chamber plates create ideal conditions for your plants to grow and thrive. The attachment is connected to the raised bed using the included hinges. The lid can be opened or closed using the two locking hinges. In addition, there is another flap on the front to regulate the internal temperature. The front flap can also be fixed and closed using two hinges. The attachment can be opened with lockable hinges. In addition, the flap on the front can be opened or closed with hinges to allow more precise temperature regulation. If you don't want your plants to get heavy rain on hot days, you can simply open the front flap, but keep the lid closed. This protects the plants from heavy rain, but the interior does not heat up too much. If you want to get particularly hot, you can easily open the lid and front flap. In this way, you avoid a too high temperature in the cold frame, which could damage the plants. The included hinges are simply attached to the raised bed and attachment and both can be securely connected to each other. Even in wind and weather, the cold frame is fixed.
