Krastorio 2 uses its own greenhouse to create wood and individual trees.
The trees obtained there are then planted ready-made, without intermediate stages of cultivation.
So planting trees is just a fake step: Plant them and chop them down immediately to get more wood than you invested, correct? BI saves this step, if you insert the right ingredients (seedlings, ash/fertilizer, water) in the Bio farm, you won't ever see the cultivated tree but get wood/wood pulp directly.
Bio Industries - uses a more complex technology for growing trees, it is more interesting and complex. But at the same time, less competitive.
"Less competitive" meaning it doesn't produce enough wood/wood pulp? That should be taken care of, if K2 is active we now produce/consume more wood to adjust for K2's requirements.
And the saddest thing is that these two methods duplicate each other, which makes it meaningless to use Bio Industries and Krastorio 2 together.
Producing wood is the core business of BI, so there's no chance to make our wood production optional. Perhaps K2 could disable their wood production if BI is active? (We do similar things, e.g. not adding our new rubber production if IR2 is active.) Guess I'll have to contact raiguard about this.
