Not the poster, but I can answer most of those questions:A few questions for you.
How much power does that manual crop farm take? I've been doing my harvests by hand...
What type of tree is that in the background?
Is that setup on a forestry tree farm as well?
And is that a natural mountain in the background or constructed? I've not seen any worldgen like that.
----- no idea!
That's a fir tree from EXBL, and it's insane for wood and sapling output. Like, woah. Grow some (planted 2x2), they're amazing.
It is on a forestry farm, on the default tree farm mode
That's most likely worldgen, I've not seen quite as impressive as that in Regrowth but I've seen things on a similar scale.
