There is X model which is a model used for Plants such as flowers but, There isn't Square Model, You know, Growable Plants such as wheats, carrots, potatoes, beetroot...
All have Square Model, if you don't know how a Square model look like, check it yourself (I don't know if square model is the real name)
It looks like a "#" but not in italic
BTW: is the delay between opening a new ticket is really 36h? It look like it is actually 18h or less... I think I shouldn't tell you that because you will change it :(
