Rubber Sapling (RedPower2)
The Rubber Sapling (not to be confused with the IndustrialCraft2 Rubber Tree Sapling) will grow into a Jungle Rubber Tree found naturally only in jungle biomes. Although Jungle Rubber Trees do not grow Sticky Resin, they can be turned into Rubber by putting logs into Extractor. Crafting the logs produces Sticks instead of planks.
Must be in the center of a 3x3 dirt or grass patch. It may take as little as 10 minutes to over 1 hour (real time) to grow. Bone meal can not be used on this kind of sapling. For information on rubber trees that produce Sticky Resin, see Rubber Tree and Rubber Tree Sapling.
