This outdoor portable walk-in greenhouse is designed with 6 storage shelves (3 tiers on each side), maximizing vertical space for seedlings, potted flowers and small vegetables. Each shelf holds up to 44 lbs, with 13.8 inch spacing between layers for healthy plant growth. The premium weatherproof PE cover is UV-resistant and waterproof, retaining internal heat while shielding plants from wind, rain and harsh sunlight. The large roll-up zipper door enables easy access and adjustable ventilation for daily watering and care. The extended 3.9" cover base can be buried or weighted down; matching U-shaped ground stakes and guy ropes greatly improve wind resistance. Adopting a foldable steel frame, it allows tool-free quick setup and compact storage when not in use, ideal for backyard, patio, balcony and seasonal outdoor gardening.
