Conversions now works only horizontally, but it might be usefull if they can works vertically.

Additional context

I looked though the code and it is set up to look for vertical up and down blocks as well as N/S/E/W blocks. It should work.

Let me clarify - only the top block will be checked (searching down from the ceiling until a block is found). Then it is checked up, down, N/S/E/W. So if there are blocks above or below it that could convert it, then it'll be converted. I think you're thinking that it should check all blocks in the greenhouse. Let me check that.
