I suppose I should get started on my cactus farm again :3 Last one got raided by an ally (which is what happened to the one before that) because my faction didn't get the memo that when you tp an ally, chances are they will take everything you have and destroy your massive money making farm! Oh well :3 Next one will be for me and a close friend only. Thanks for the statistics @Kris !
Or you could make this on a larger scale (all depends on the redstone you can afford): This mechanism is quite common, it doesn't look very nice but it works (you can place blocks in front to prevent the items from falling outside the water, I removed them for taking the screenshot) and it's all automatic, the only flaw is that the number of pistons you can reach with 1 furnace is limited as you can see in the picture (last two blocks aren't powered), I'm working on a solution for that. As alternative you can just use a lever: Sometimes the melon/pumpkin fall on the ground rather than the water, but you can fix it enlarging the duct, it's still faster than manually doing all the job of gathering anyway. Both methods can probably be optimized, these are just concepts I put together in Creative, while I was waiting for Survival to come back online.
Cactuses is best way to make money, I dont have fly, but I made big cactus farm, and I am earning about 60-80k per day.
@Johannesvanurk Why isn't @aXed replying to my Support tickets or Posts he Replied once then never said a word again ?
