The CLOUDLAB 894 Advance Grow Tent has an optimized space for growing up to 18 plants in a fully sealed environment all year-round. The strong frame built with 50% thicker steel poles is extremely durable and can hold twice more weight in comparison to industry-standard grow tents. The 2000D oxford canvas is highly light-proof while the mylar lining is highly reflective, thus, giving you full control over the environment. The SBS™ zipper paired with a flap makes it easy to access without any unwanted light penetration. Tall and wide windows offer full display inside, and duct ports permit complete optimization of the space with heaters, humidifiers and A/C units. Holding up to 150 pounds, this grow tent can handle its equipment with no difficulties.
