I would highly recommend a Cool Grows tent instead of the vivo. I read through so many of the reviews of the vivo and a lot of them complained about the blackout material fading out and causing light leaks. I've got the 2x4x5 tent and it fits 2 plants just fine. I tried to grow 3, but 1 ended up being male so I tossed it. Honestly didn't have the room for it anyways.
