This walk-in greenhouse gives a backyard or garden a lasting 6-ft x 8-ft growing room with 6.5-ft of headroom at the ridge. Transparent polycarbonate panels spread daylight across the interior while shielding plants from sun, rain, wind, and snow, and the rustproof aluminum alloy bars carry a 110-lb snow load through winter. Built-in rain gutters channel roof runoff through a spout and funnel so water drains clear or feeds a collection barrel. The roof vent sets at three angles for airflow control, and the 2-ft x 5.5-ft sliding door rolls open for daily tending.
