One of the most efficient crops to grow in Minecraft is the melon. While not the best at boosting your health meter, melons require little work and they take about as long as wheat to grow. The best thing about melons is that once harvested, they will essentially grow back forever and with a little redstone, the work is practically done for you. Indeed the only trouble with melons is getting their seeds in the first place, which requires looting abandoned mine shaft chests. Below, the necessary steps for creating an automatic harvester to get you started on your own automatic melon farm.
Step 1 Dig an Irrigation Trench
Step 2 Add the Auto Harvester
Step 3 Plant Your Melons
Step 4 Harvest Your Melons!
Now all you need to do is sit back and let the melon crop do the work for you. You can survive on melon alone with the press of a button. As long as your redstone is wired up to repeaters you can make your melon farm as big as you want. Enjoy!
