The spitfire farm is a farming machine in Locke's Lab that converts bonemeal into wheat, far faster than even the largest farm. User interaction is required. Don't worry, ManaLocke supplies the bonemeal.

ManaLocke got the idea from discussions online, but designed and implemented the concept himself.

Operating the farm requires some setup. Ensure the bonemeal dispenser is stocked (if it isn't, contact ManaLocke). Open the seed dispenser and take one seed. Place it in the leftmost open space in your active bar.

Walk forward, and press up against the stone ledge. Aim the seed at the plowed farmland. Then right-click and hold.

When you're ready to collect the produced wheat, throw the lever at your feet. Always leave the farm as you found it.

The placement of the seed in your inventory is key. The technology exploits the fact that when you plant the seed, the selected tool spot becomes empty.

When you place the seed, a Block Update Detector detects the change, and spits out a single piece of bonemeal. This is immediately used on the planted seed, growing it instantaneously. The update detector detects the growth, shifts and replaces the ground (so the wheat pops out), and puts another seed in your hands. Repeat ad panem.

• from Nether: Follow the pathway out and to the right, and at first opportunity turn left twice.
• from DTA Railway: Head straight out from the station, go to the back wall, and turn left.

Go up the stairs and follow the signs out towards the surface. As soon as you reach the top of the ladder, go left around the stairs and turn right. Go down the stairs there to the auto-farm, and turn completely around. The spitfire farm is beneath the most recent set of stairs.
