It's a custom pack, bit like DW20 pack but minus IC2, with Mekanism and a few other new mods that I feel DW20 would have fun with. Doesn't have magical crops or Witchery.Thanks for the suggestions.What pack/mods do you have available? Magical crops comes to mind, it is what I use and can produce vast quantities of dirt with a minimal investment. Witchery can convert stone or sand blocks into grass via the Rite of Nature's power. Haven't tested the area on it but if it is anything like the rite of fertility it has a radius of ~50 blocks. you would still need to dig them up manually however.
I think I will go the forestry route. Don't care how slow it is, as long as it's automated.
