Hey guys new farm design. this one is auto harvestable. it only needs 1 water stream instead of it being impossibru like on my last, square model. this one is a circular design, (because the water travel path is circular) it has a very high yield, though i haven't checked them yet. i'll get back with that.
the outline of stone bricks can be any block/can be left out and dug into a little central gathering point. it can be made with any circumference, the only thing that matters is that there is an exact center (marked by stone brick on top) for the water to land on, which will in turn, spread and harvest your wheat.
it took more thought than it should have, solely because i usually don't think of circles in minecraft. anyways i basically fused circles with terraced farming and got this. you gotta love having an engineering class at your highschool. (we all get computers, after we finish our assignment for the day we get to do what we want. sometimes i decide to design stuff on minecraft. also i love graph paper.
