The Year-Round Cold-Frame is perfect for getting a start on your growing season. The polycarbonate mini-greenhouse is designed to prevent early growth from becoming frost bitten, but when traditional cold frames are no longer practical because they become to warm this unit has an other cover with insect netting. Simply slide out the polycarbonate panel and the netting will prevent the young plants from either being damaged by insects, birds and/or heavy wind and/or hail damage. This Cold-Frame also features two ropes which allow the lid to stay open vertically and not fall over. This top quality Austrian Cold-Frame provides perfect insulation in spring and autumn with double skin panes. Made with 4mm twin-wall polycarbonate. Measures 50 x 23 x 12 Inch (high front), 16 Inch (high back).
