Already did that actually. I should link it in the description https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1634004405

As a suggestion about this: get rid of the constructors. You don't need them and the space can be used for additional storage, crop plots or whatever. Place portable constructors in front of the building, they can craft bio fuel but don't require an energy source. That way you can usually get rid of the emergency energy supply which gives you even more space.
Nimrod, what do you tink about building a modified version of this, at least without constructors?

Thanks. Yea I think they ought to make the fiber plants produce a log worth of fiber each and then reduce the amount you get from a log. Tree harvesting would probably still be faster but 144 plant beds to fill one small HV fuel tank seems a bit much.

Hm. Funny story: I just saw a post on EGS forums about fiber plants being too nerfed. That remembered me of a greenhouse bp I saw a few days ago. There I found a collection. subbed to 3 greenhouses before I realised who was the author. The creator of so many nice greenhouses writes about the one plant that always had an own greenhouse in my bases. Well done I guess :-P
