Crop-Matron

The Crop-Matron is a machine that will apply Weed-EX, Hydration Cells and Fertilizer as needed to all plants within a 9x9x3 area around it.

It requires 1 EU/t, thus being able to run with only one Solar Panel, however you may want to use 2 Solar Panels and a BatBox as solar power will not work at night and the device does not possess internal energy storage. It accepts 32 EU/t before exploding. However, you should instead use four Water Mills as the EU they provide is constant (unaffected by night or rain) and they are more cost effective than two Solar Panels and a BatBox, although they will take up more room (4 3x3 cubes of water plus cabling and BatBox vs. two 1-block Solar Panels and a BatBox next to the crop-matron).

Weed-EX, Fertilizer and Hydration Cells are either added manually by pressing "Right Click" on the Crop-Matron, or automatically through Logisics Pipe. A Crop-Matron will hold three stacks of Fertilizer, three Hydration Cells, and three cans of Weed-EX. It uses the supplies quickly, so good timing is required to make sure it keeps a good supply on hand - otherwise the Crops it is tending could be taken over by weeds.

Automation
Crop-Matrons are difficult to properly automate, to say the least. It seems the Weed-Ex needs to be fed through the bottom, Fertilizer goes in the side, and the Hydration Cells need to go in through the top.
