not as much. i used to do them before, and the issue was, you dont get too many logs because they cost more than the herbs to collect. i found doing the logs were about about 20-25m less than the herbs.. but this is as of 2018 idk if things have changed since. i'm going to give it a try and see what i come up with. but the best way to make the planks is using the invention guild auto plank making machines. cheaper than spending the money on sawmills.
