More spacious, the CLOUDLAB 866 Advance Grow Tent has the perfect balance between high-quality materials and innovating craftsmanship.

With an extremely strong frame built with 22 mm diameter poles and 2000D oxford canvas, this tent is set to last for many years to come. The interior, lined with reengineered mylar, is highly reflective. The SBS™ zippers work to provide easy access and the extra flaps work as a light-proof layer of protection.
