Sized at 55.5 x 56.1 x 78.7 inches, this walk-in greenhouse gives you enough headroom to move around freely while tending plants at eye level. Four shelves spread across two tiers, eight in total, hold up to 33 pounds each, leaving plenty of room for pots, trays, and grow lights without crowding the floor space. The frame is made from rust-proof steel tubing measured at 0.02 inches thick, built to hold its shape season after season, and the roll-up zippered door makes it easy to step in and out without wrestling with the whole cover. Screened ventilation keeps air circulating so humidity doesn't build up around your plants. The waterproof PE tarp cover offers level 6 sun protection along with high light transmittance and diffusivity, so plants get the sunlight they need without leaf-burning hot spots, and its transparency makes it simple to check on growth from outside. Assembly is a one-person job with no tools required, just connecting the rods per the included manual, and the structure is light enough to relocate as the seasons change, whether it ends up on a patio, backyard, basement, or garage.
