Buildcraft farm

Note: My modpack is "slightly" bigger than your tiny testing one (including HarvestCraft), but I don't think anything modifies Immersive Engineering crops. Tests with more precise modpack soon.

Hemp farm is among the easiest farms to set up. Because hemp grows 2 high robots only harvest the top block, letting the bottom one to regrow without the need for replanting - same goes for pumpkins, melons, sugarcane and cactus (probably, not tested).

In simplest case, the farm only needs a harvest robot and some form of item pickup - can be done using another robot, but I had an issues with them - I haven't figured out all config kinks. Hopperhock will probably do the job faster.

For the single robot only 5 things are needed: kinesis pipe connected to a power source, a gate (any will do), robot docking station, a Buildcraft map and a Zone Planner. Oh, and the harvester robot.

First of all, you need to make the farm and plant the plants. A nice, contrasting border around the farm would probably help in the next step.

Second step is to define the farm area - place the zone, drag around the farm area in the GUI, put the map in the top right slot. It will encode the farm area onto the map.

Next, robot docking station needs to be created. A kinesis pipe needs to be connected to a power source (wooden or emerald if connecting directly to an engine). On the pipe there needs to be a docking station and a gate.

Gate configuration: redstone off = work in area + previously configured map
		    sleep	 = wake up

Now all you need to do is to place the harvest robot on the docking station. Robot will fly to the nearest fully grown plant in the marked area and break it.



Automatic planting:
An easy upgrade to the farm is the ability to plant the seeds:
 * two more docking stations
 * one more gate
 * wooden transport pipe
 * A chest for seeds
 * Planter robot
Place wooden pipe on the chest, gate and the docking station on the pipe. Place second docking station on the kinesis pipe and place the robot on it.
Gate configuration for the wooden pipe : items in inventory = provide items

Automatic tiling the earth can be accomplished by repeating the previous step, only with a farmer robot. Both planter and farmer robots can share the same chest (and wooden pipe with its gate and docking station) if you want to manually supply hoes.
