Hi, I'm thinking of setting up an automated way to harvest the wood that grows out of a planted root seed.

I'm thinking having four auto-drillers pointed at the four sides of a planted root seed, so that anytime it grows, the wood will automatically be cut away.

But maybe there is a more effective way? I am not sure how exactly the wood growth works. Maybe you get more wood faster if you let the seed grow out a bit - perhaps every wood "tile" has a separate chance to push a new growth onto a random neighboring free tile?
