This slim walk-in greenhouse measures 55.5 x 29.3 x 80.7 inches, fitting into a narrow side yard or patio corner while still giving you room to step inside and tend plants. Four shelves hold up to 33 pounds each, enough for seed trays, potted plants, and small garden tools, and the frame uses rust-proof steel tubing at 0.02 inches thick for a structure that holds its shape over time. A roll-up zippered door makes daily watering and harvesting quick, and screened ventilation keeps air moving to prevent trapped humidity around your plants. The waterproof PE tarp cover provides level 6 UV protection with high light transmittance and diffusivity, letting sunlight in while guarding against leaf burning, and its transparency makes it easy to check on plant progress without opening the door. At about 15.4 pounds, the whole structure goes together in a one-person assembly with no tools needed, just connecting the rods per the manual, and it's light enough to move as the seasons change, whether you're setting it up in the backyard, patio, garden, basement, or garage.
