Today I am selling a MANUAL sugar cane farm. It yeilds a VERY high harvest per 1 layer at full height. 2.5 stacks to be exact. The farm also takes up very little space. This farm type can also be stacked and is symmetrical! Buy it today at the low low price of 100r per layer! Only 200r for 2 layers and so on! I am sure this design can be modified to be automatic but I will not be the person to do it. I have an example on my third res on smp4.
