768 Cocoa beans

48 x 4 = 192
192 x 4 = 768
768 x 2(3 cocoa beans harvested, 1 put back) = 1536 total cocoa beans!

on the Skyblock server, this is 24 stacks which costs $1200 per harvest.

Total harvest time is about 30 mins, a little less with no problems. 

I had an auto farm, but i'd only get about 6 stacks, using all 4 sides literally quadruples the amount harvested. There is really no way to make this an auto farm. :/ But its looks cool this way, so I prefer this. >w<
