All you need to do is place it and add dirt or soul sand if planting nether wart. The pots don’t need water so this is a great and compact system. Then place your seeds in the pot and watch the growth!
It also takes up significantly less space when planting melons and pumpkins.
Crops will grow a bit slow but can be sped up with bonemeal like normal. The other key feature of this mod is that once you harvest, the pots will automatically plant the next seed for you.
