Using the Planter, Fertilizer and Harvester [Emerald Upgrade in all three, made a 25x25 area] as well as an auto animal farm producing sewage which in turn made fertilizer,I had a huge farm collecting the wood/resin/saplings. I made the area they were planting in checkerboard, so one stone, one grass, one stone, one grass and so on...
The wood and reson would be imported into an ME System which then send the wood and rubber to be extracted and the rubber stored in Deep Storage Units. The saplings would either go back into the planter or stored in the ME System.
