The greenhouses can grow trees on gleba, but you can't process the seeds in the lumber mill because of the pressure requirement. Allow the lumber mill to bypass this requirement so you can process trees into seeds on gleba.
Is the pressure requirement for the Lumber Mill or for the seeds? If its for the seeds its a vanilla thing i wont change
If its the lumber mill... It has no limits. You just cant craft it on gleba
The pressure requirement is for the recipe in the lumber mill to process wood into seeds. You could probably just remove that recipe and replace it with an identical recipe only usable on the lumber mill that doesn't have a pressure requirement
