Perfectly sized for the beginner gardener or someone who needs a small growing space, this compact greenhouse is attractive, functional and sturdy. Crystal-clear panels let in 90% of sunlight and are 100% UV-protected so they won't yellow. Start your own vegetables and annual flowers from seed, harden off indoor-grown plants, propagate perennial cuttings and nurture tropical plants even as the weather chills. Long-lasting galvanized steel base and aluminum frame, with a magnetic swinging door that locks. A vent on top allows you to increase air circulation and let excess heat out. Gutters channel water where you want it and make it easy to collect rainwater, too.
