It irrigates just like an industrial cooker. You snap pipes directly to it and lead the pipes to a water tap. Keep in mind you'll need to use some sort of modded pipes to be able to put them on rafts, so the Raft Pipes mod for example. IIRC Structures+ also has a raft-compatible pipe system.

Ahh okay thank you so much ! :D

Reviving an old thread here.... does your advice still apply? I put a rain barrel on the roof of my raft with a cauldron on the next level down, directly below. Tried connecting with S+ vertical pipes but still can't get the cauldron irrigated. Should my set-up work? You mentioned, @Finalizer, that the pipes need to go into a water *tap*, but typically you don't do that with a water tank, just lead the pipe into the tank itself; the water barrel is supposed to work the same way, is it not? Been trying all kinds of combinations for eons but I'm at my wits end. Spent way too much time fretting about this already... any advice would be greatly appreciated though.... Cheers

Figured it out... as simple as placing an S+ intake valve on the raft and piping it up from there... no need for the rain barrel.

If you use the food tray you can irragate this with the waterbucket

S+ interior pipes (with the big S for square) work too

thanks all for the responses
