!@%@^ it.

Screw you, Dwarf Fortress. I planned this level as a tree farm and by Armok it will be a tree farm. Masons! Start building floodgates. Mechanics! Start building mechanisms. Wall-building team! Build aqueducts throughout this entire level. I don't care if it will take 50 dwarves three years. THIS LEVEL WILL GROW TREES BECAUSE THAT IS WHAT IT SAYS ON THE PLANS.

hehehe i did that once when i first started playing with 40d, before i realized i needed an underground river or pool (but didnt have one)

i didnt play for a while after that sad realization...

If you have any water source, then all you're facing is an engineering challenge.  Are you dwarven enough to pump water up from the caverns to flood your erstwhile tree farm?

[Eoganachta]

I tried making an indoor park with a river flowing through it and trees growing on eitherside below my fort. Didnt go so well.

Yes, but I'm also dwarven enough to know there's a river above my head, and down is easier than up.

Oh, the memories of using almost nothing but gravity in my 40d obsidian farms...

Well I flooded that sumbitch but good. Now the dorfs are swimming through the "3"s and tearing down the retaining walls. Future flood projects will be a lot easier, I learned a lot doing this. Mainly:

You don't need to run pipes everywhere. Gravity feed from a brook will flood a huge area before the dispersion and evaporation slows it down. On a 2x2 embark, I think I could have gotten away with just two walls dividing the embark into four squares, with gates in between. (I ended up building like 20 zones which was gross overkill.)

If you want it to drain fast, you will need multiple drains. I've got one 2x2 drain in the middle and its taking months to pour out. Luckily there's no rush, the trees are growing just fine underwater.

From the wiki: Pipes, or pipe sections, are used as components in the construction of screw pumps. You can't build pipes by themselves in the current version, nor connect them to form a conduit - to move water or magma from one place to another, see aqueduct.

I'm confused :S

I got great results with tree-growing in a large underground area *(by accident)--

basically build a pump facing backwards, have it endlessly filling an enclosed space.  The back of the pump, including the pit you are pumping from, should face the room you wish to be forested.  There will be lots of mist and the mist will gradually accumulate, filling your whole room with a 1 deep pool of water. To guarantee easy control,  build glass windows in a chess-board pattern, this (and burrows) will let dwarves enjoy some emergency mist if they need it, while negating water pressure.  It took about a year but the room was almost constantly a little wet, and many many trees sprouted.

two things:

1. You have made sure to breach a cavern layer, right?
2. sometimes plants seem reluctant to grow they are on a soil floor with a layer of stone beneath

Pipes in the sense of a one-tile wide walled tunnel to carry water from the brook in the SE corner to the other parts of the map, not pipes in the component sense. Sorry for the confusion.

Fascinating idea. Gonna have to try this one. How big an area could you cover?
