Compost wood or spoilage into artificial grass tiles that consume pollution.
Build Zen Towers for compact wood production on Nauvis or Gleba.
Grow wood in Zen Gardens on any surface.
The Artificial Grass tiles can essentially be used as cheaper Foundation, which I don't think should be possible. You can't even grow trees on Fulgora or Vulcanus so it doesn't make any sense there.
Please check it out and report any issue or other feedback.
Known issue: if you cover foundation, or Aquilio tile with concrete, grass can be still placed over it removing the foundation and concrete. But you can no longer have free early foundations.
Due to my knowledge this can't be solved in data stage.
