Hybrid wheat is an improved version of the vanilla wheat crop, in that it can grow up to 3 blocks high. It drops normal wheat when harvested. It is grown from Hybrid Seeds
Due to the fact that it grows three blocks high, you can set up automated wheat farms in much the same manner as you may set up automated sugar cane farms, this can allow you to harvest large quantities of wheat without needing to spend time manually replanting the crop.
Hybrid wheat seeds are obtained by combining Wheat Seeds with Redstone. Hybrid Wheat will drop Hybrid seeds rather than regular wheat seeds.
