I need greenhouses

I wouldn't call it beautiful, but it's an easy way to set up a greenhouse with sprinklers so you don't have to water every day if you choose not to.

Build a room with medium wall height. (Trees won't grow with short walls) Add the glass roof tile, and windows.

Use the sledgehammer tool to knock out the floor then the exposed wall between the windows.

Then, if you have seasons, you can add your sprinklers and all your plants will grow year-round! Yes, I'm a lazy gardner :p

Now if you go fishing at the Magnolia Promenade dock you can catch a dragon fruit and get filthy rich. :)
