Mar 31st 2012 #1 I set up a automatic tree farm using RedPower2 and IC2 rubber saplings. I want to know how long in average it takes for a rubber sapling takes to grow into a rubber tree.
Mar 31st 2012 #2 I put up a farm of six rubber trees and the first one grew in ~5 minutes. Two of them didn't grow at all in 15 minutes so I suggest using bonemeal.
