I ‘upgraded’ to a 4x4 tent from Vivosun from a Topolite 2x4 tent. The A shaped ceiling isn’t my favorite but and 80in tent ended up being 81.5 inches and was too tall for my new space. I switched to the 72 inch tall Vivosun. It’s ok. I wish there was a taller entrance (maybe one of the sides is better). The viewing window is nice. Plenty of inlet and outlets for cords and exhaust duct. Be wary of sativas and other tall plants.
