Garden bed and mini greenhouse integrate so you can start seeds, harden seedlings, and grow vegetables in one outdoor planter setup. The color steel raised bed forms a 71 x 24 x 12 in planting box that holds up to 86 gal of soil, while two thickened middle bars add support against outward soil pressure. A clear PVC cover traps warmth, sheds rain, and helps shield plants from frost and animals. Protective frame edges and an open base let roots reach native soil and drain naturally for healthier growth across seasons.
