A 47-in by 21.5-in mini greenhouse that fits over a raised bed or stands on a patio, holding warmth around seedlings weeks before the last frost clears. The PE cover blocks rain and screens harsh sun while still passing light through to the plants. A 40-in by 30-in door rolls up and zips shut, so venting heat on a warm afternoon and reaching the back row both take a single motion. Extended bottom edges hold bricks or sandbags, and six ground stakes pin the frame in wind. The 4.5-lb structure clips together without tools.
