Thank you for doing the screenshot. I couldn’t get to the game to do it.
So I put a walk way on each side of my field and made it smaller before I did the angle down. I then had water underneath the walk way to support the normal growing process. The walk way allows me to then turn on flowing water and allows it to flow down over everything. I let that run to grow and turn it off to harvest.
It is that angle though that cannot be 100% when I am trying to harvest. I think it is how I have the water on the side under the walk way… I just haven’t taken the time to figure out where I went wrong.
