A greenhouse section would be good to compile all the information in one place, so when someone new to greenhouses tries to figure out what to do, there is no need to use the often-clumsy search function.
I understand all the arguments about not wanting to subdivide the forum too much, but I think that at least a greenhouse section would be a good addition (to compile all info in one place). If I have to choose one of the two new sections up for debate, I’d choose the greenhouse sub over ultra tropical.
