Map of greenhouse

[smbantjes]

Can you also make maps of greenhouses so that plants can be also located in greenhouse areas

I think so. I suppose you can handle internal paths in a large greenhouse similarly to alleys in a big warehouse. I'm not so sure, but I think that the OSM tag "highway" has a value for internal alleys.
have a look at the OSM guide for indoor mapping.
examples: covered: yes; highway: pedestrian, or highway: footway, ...
