Treefarm 3.0 complete and fully operational! Finally!
There's a chest in the basement with all the extra saplings, plus I've planted 2 fir and 2 redwood for your eventual removal. One of the redwoods *just* cleared the bottom of the glass in the lower veggie farm. 58 blocks tall!
Have at it. I'm starting my move to the autumn biome.
*note: you can put any extra reeds, cacti and cocoa in the same chest. That's where I'm putting the harvest from those if you want to grab some.
*note2: turn your "fog" setting off or you'll never find shit down there.
