It will still grow canna!! I do think there is a discernable difference in the various tent mfg material and design.
It's very obvious between Gorilla and Mars. I would assume it to be the same or similar with Vivosun.
Longevity may differ, but but design definitely does! The first KEY design difference is tent height!!! They are all shorter than Gorilla........ BEFORE any extension is used.
Inlets, air and electrical, are placed better in the Gorilla VS the Mars.
The tent height is very key to me! Not only for taller girls, but to keep the heat at the top of the tent and away from the girls!
