Hi guys, I am new to the modding community as well as modded mine craft. I've been watching videos on you tube with mods for a while now and have become extremely interested. I am looking for a mod that focuses HEAVILY on industrial, electricity, anything really that deals with automation of some sort. MFR, AE, things like that. However, I also want one specific mod, magical crops. Do you guys know of any tech heavy mods that include magical crops and aren't just ridiculously taxing on a computer like FTB?
