I came up with a workaround (config) that should allow the default greenhouse that comes with kerbalism to use a rate based food per second output instead of having to go to the ship and harvest the food when the harvest is ready every 200 days. This sets the harvest time to >1000 years and adds a resource output of food (along with oxygen) that should match the old output. There are also configs that modify and add the greenhouse functionality to the Stockalike Station Parts Redux greenhouse
