This farm is a very complex, high output design cactus farm. If you do not have a computer with very high specs, you may experience lag, and it will slow down the amount of items you get per second/minute/hour.

I currently have the design at 95% complete, because while I've had one other person help verify the items/hour, I would like to make sure that it's correct. Anyone with a very high spec computer is welcome to help test this, and verify the numbers are correct. I don't want to end up lying to anyone.

With the current information gathered and tested, the farm produces 243,952 Items/Hour

Additional Notes

Design Information

The design is 145x145 blocks in size from bedrock to sky limit.
102,240 blocks of sand used with one cacti on each.
Uses complex waterflows built with McEdit to minimize carrying space and allow more room for cacti placement - These flows can be stopped if a block update occurs beside a flow, so take caution when placing or deleting a block on the carrying system.
