I did a post on this. In the greenhouse alone, you can easily clear a million per season, a million and a half if you are willing to put up with a more micromanaging project.
Here is a
finely crafted link to that post.
The tl;dr is: Ancient Fruit, with Peach or Pomegranate trees and hops in the greenhouse if you really want to max your profit margins. Peach and Pomegranate trees produce their respective fruits daily, and in the greenhouse they will produce all year long instead of just in their season, making them the single most profitable single square in your greenhouse. Hops is brewed into Pale Ale which sells for 300g or 420g with Artisan, and hops produces daily, making them the second most profitable crop in your greenhouse. Then infill with Ancient Fruit for weekly harvesting and weekly brewing. Nets around a million and a half just from the greenhouse alone.
For a less micro-intensive build, 116 ancient fruit brewed into wine will net you close to a million per season and a one day workweek, leaving the other six days free to do whatever you'd like.
