This walk-in greenhouse packs real growing space into a 55.5 x 28.3 x 78.7 in footprint, making it a fit for backyards, patios, basements or garages alike. Rust-proof steel tubing measuring 0.02 in thick forms the frame, and four shelves across two tiers each hold up to 33 lbs, giving you room to organize seedlings, potted plants and grow lights without crowding. The waterproof PE tarp cover offers level 6 sun protection with high light transmittance, so plants get plenty of light without the risk of leaf burn, and the clear panels make it easy to check on your garden at a glance. A roll-up zipper door opens wide for access while screened ventilation keeps air circulating for healthy growth. At 12.8 lbs, one person can assemble it without tools by simply connecting the rods, and it breaks back down just as easily for storage or moving between seasons.
