Build more greenhouses?

I'd like it if after you've unlocked the first green house, then Robin could build more of them. I'd have part of the materials include a bunch of refined quarts for the glass

 

That seems kinda OP to me. Fill a greenhouse with ancient fruit crops and you get at least 70k a week. I get there's the negation of season limitations, but I think the limited space makes you plan more with what you have open for crops.

 

I recall a thread like this in suggestions already.

 

I thought I'd seen one months ago but couldn't find it to see what the consensus was
