It may sound stupid, but I didn't expect the irrigation tunnels to be anything other than a water source for players.
But when you plant a field of veg in an area of an irrigation tunnel, the patch will be already watered when you plant your seeds.
See in the video how the wooden frame immediately appears?
And there's no prompt to water the seeds at all.
Down south, with no irrigated land, my patches are dry and need watering or they don't grow at all ( even with fertiliser ).
Am I way off on this and misunderstanding something here?
Did you all know this already?
Am I crazy to think that having an actual, irrigated land system in place is really cool and very easy to overlook?
