This is the structure meant to facilitate the controlled growth of IndustrialCraft2 rubber trees. A BuildCraft2 Filler is used to rapidly turn the blocks into collectible entities and RedPower2 Transposers are embedded into the floor and configured to collect the drops and pipe them to a central collection chest which is then piped out using BuildCraft2 pipes into IndustrialCraft2 Extractors, producing Rubber and piping those into a final chest. Everything is automated minus the manual hand planting and switch pulling.
