So I was a huge fan of Steve Cart tree farms until the mulitblock farms and tree breeding came along. Once I was able to breed a tree that had fastest growing, triple saplings, high sappiness and produced apples it was all about the mulitblock farms. One max sized mulitblock with my hybrid trees so put to shame my 3 Steve Cart farms it wasn't funny. Not only did they produce more saplings but they produced way more apples so much so that I was able to convert all of my fermenters over to apple juice with apples to spare. While this setup is in my opinion leaps and bounds above Steve Carts it is not for early to mid game. The server I play on was just reset and I looked into going right to the multiblock farm setup but it just isn't there. Steve Carts are easier to setup on day one.
