hey Pepsilian,
thanks for your comment. That with the seed is intended, but give a simple trick. Inserter fueld inserter. In other words, if I automate wood and supply the "seed inserter" from the wood band with a inserter, it will never pick seeds because it always has wood in the inventory (unless wood is no longer produced).
If necessary, I make a small picture of how I mean that and would put it on the fashion side.
