that's useless though as far as I've seen. I do it seed|farmer|buff|farmer|seed , like this, you can buff up to 8 farmers with 1 buff tile, and on a long line, maybe a line of 10 farmers, some of them can get up to 8 buffs.

I didn't even think of putting the workers in between two different seed nodes. I have an idea for my next run now.
