In this mod you will find carrot seeds that drops when breaking grass (Just like the wheat seeds)

Use this seeds on different vanilla ores and ores blocks, or even on tilled dirt.

Each carrots will give you different potions effects.

There are also 2 craftable carrots one of this is just to be able to craft the Ultimate carrot, this carrot you wont be able to eat, but when you have it on your inventory, you will be immune to wither effect.

Want faster growing? You can use the Watering Dongle from my mod Mike Dongles or you can try venting on the crops with Crop Dusting.
