Growing Space - 8" (20cm) front panel enables seed trays to be placed right up to the front edge of the cold frame, with room for the seedlings to grow. The lid slopes up to an 8" (20cm) flat top, allowing smaller plants to be placed towards the front of the frame, larger plants towards the back. Cold Frame Shelf - 6" (15cm) wide x 48" (122cm) long aluminium tray 8" (20cm) from the top of the cold frame ideal for half or quarter seeds trays or single pots to catch maximum light. Base - an unglazed base with four angle brackets, allowing easy anchorage to gravel, paved or grassed areas - either permanently by screwing through the pre-drilled holes or weighting across the bracket so it can be moved if required. Placing directly on soil gives the added option of being able to grow straight from the ground - giving your plants a gentle start & moving the lightweight cold frame as they become hardy. Dimensions: 4' (122cm) long, 2' (61cm) wide, 2' (61cm) high.
