... and you can use ironwood planks in place of iron ingots in various iron based recopies ... or maybe not... that might be a bit to OP, being able to grow your own iron... LOL... I suppose it could just be limited to tools and weapons if that isn't too potentially abusive.
I would think in order to make it not op, they would just be made into regular planks and regular wood tools, but the wood and plank blocks themselves are much harder to destroy and light on fire.
