This is a build for a large automatic greenhouse, it is 64 x 32 x 16 blocks in size, inside there are 8, 9 x 9 crop plots that are harvested by a gantry contraption, I generated the schematic so that the contraption was placed in the middle of the farm so you can make sure everything is glued together before starting it. The build also has a size 4 steam engine included in an outbuilding at the back which can be used to splice power off for additional crop processing or farms. Inside the outbuilding there is a crank connected to a large cogwheel to turn on the engine, after that is on passive make sure the lava farm is working and the spout has a bucket, then connect the small and large cogs for the pumps and farms, and then the shaft upstairs to turn everything on. Out the backside of the greenhouse there is a drop off for crops, I would recommend list filters to sort the crops into the vaults as desired.

For the build itself I have left a clipboard attached to the outside wall of the outbuilding that has the parts list. There hopefully aren't any issues as I always try to be careful about my building but if there ends up being an issue feel free to let me know and I will try to fix it.

The only mods this requires are Create as well as Create: Re-Chiseled for some of the decorative blocks, so I think it will work even if you don't have Re-Chiseled, you just may have to fill in some gaps in the floor and walls.
