Compact enough for a small yard, this galvanized bed measures 4 feet by 2 feet with a 12-inch planting depth and holds 57 gallons of soil. The PVC greenhouse cover clips over the top and raises overall height to 3 feet, creating a warm pocket for seed starting in early spring. High light transmission keeps seedlings growing under the hood, and the extended cover edge can be buried in soil or weighted with stones to seal in heat and keep small animals out. Heavy-duty galvanized panels resist rust and warping, a reinforced support bar spans the middle, and corner brackets round off the sharp edges. Use the two pieces together through cold weeks, then lift the cover away and grow in the open box once nights warm. Assembled weight is 18 pounds.
