Mammoth Pro+ HC 300 is a 9.8′ x 9.8′ x 6.6′ grow tent engineered for high-capacity gardens and advanced growers. The Pro+ HC construction combines an extremely sturdy frame with heavy-duty fabric to support multiple high-output fixtures, large filters, and complex ducting. The reflective inner surface maximizes light efficiency across the full 10′ x 10′ footprint, while well-placed doors and vent ports make it practical to manage and maintain a large, productive canopy.
