In-Depth Information
Use a sticky piston to drop water from a raised water source so that it flows out
over the farmland.
Use a dispenser containing a filled water bucket to send out a stream of water.
Figure 6.14
shows a farm built using the first method.

3.
Lever set to “On” because this type of harvesting only drops water when the
power goes off
4.
Row of sticky pistons in their extended position holding back the water
5.
Redstone repeater required to amplify the power due to the length of the cir-
cuit

Water source used for harvesting, suspended by the extended pistons

Figure 6.15
shows a simplified view. The water source is held in place by the surrounding
blocks. In Minecraft's geometry, the extended piston beneath also prevents it from flowing
down. However, as soon as that piston is retracted, the pathway through the block under
the water opens, allowing the water to flow out over the crops.
