Makes use of 10k flowing fluid blocks to get infinite fuilds. Only need 2 actual buckets of fluid. On at the bottom and 1 at the top. Take out the cobblestone supports after top fluid is dumped. I use the destruction wand core for this. For most fluids (not lava) you need at least 10,000/(14*14) blocks of clearance, or 52 empty air blocks between the top and bottom.
