Trees

None of the Calculator trees occur naturally, they can only be made. There are currently four trees, each of a different tier with Diamond being the highest. As of version 1.8.5 the trees start with nothing on their leaves and you must wait for them to grow, once picked they will grow back. In earlier versions none of the drops from trees regrow, their saplings had to be made again and replanted.

Tree harvesting can be automated with Assimilators.

Used with Hunger Modules. Created using a Large Amethyst and any vanilla sapling (Note: Some mod saplings may work) in a Scientific Calculator. Yields hunger points when right clicked with a Hunger Module or if the logs/leaves are placed in a Hunger Processor. Alternate crafting method is Amethyst Leaves and Amethyst Log in a Scientific Calculator.
