The Tree Growing Simulator mod will add a new way to accelerate the growth of trees in minecraft.
You just need to run, jump and dance next to them and you will not notice how the tree will already grow. This method is in no way inferior in the growth rate of inert flour.
How to install the mod:
Install all additional mods if specified.
Download mod and copy to .minecraft / mods
Launch the forge version of the game in the launcher.
