Editing 40d:Tower-cap

'''Tower caps''' are a type of [[tree]] which only grow underground (subterranean). Once fully grown (which takes 3 years?{{verify}}) they can be designated for wood cutting like other trees, and produce Tower Cap logs.

== Tree Farms ==

It is possible for tower caps to spontaneously grow in muddied subterranean areas <b>only if</b> you have discovered an underground [[river]] or underground pond. Unfortunately this is currently extremely difficult to do.


On the subject of spawning Tower Caps, Toady said:
<blockquote>Right now, you can't plant towercaps or bring spawn along, so you need to find a cave river or cave pool, in which case they will start growing underground if it's all working. It's trickier to find such things, so it's mostly impossible to do. Later, you should be able to plant them. There are no arbitrary vegetation caps now.</blockquote>

The "arbitrary vegetation caps" comment is referring to the old limit of 200 trees growing by the [[cave river]] in the mud.

== Designing a Tree Farm ==

To create an underground tree farm, you will first need to dig out a large area (in this example we'll go for 24 by 24, inside dimensions). Now, we need to do some math, so first let's take 24 times 24, which is 576. Divide this by 7 (the number of water units in a full tile) and round '''up''' (this case it's 83). Now, once again, divide 83 by 7 and add this number rounded up (12). Repeat the previous step for an extra two squares. Now, let's take 83 plus 12 plus 2, which equals 87. Inverse square this number and round normally to get a 9 by 9 square with an extra 7 tiles added on. You'll want to dig a 1x1 hole in one wall of the tree farm, which will attach to the filling room. This filling room ''must'' be the same size or perhaps one tile larger than the number you came up with. Dig another 1x1 hole in the far end of this filling room and then dig to your water source. BEFORE breaching the water source, place three doors: one in the first 1x1 hole, one in the second, and a third in your woodcutters' access path. When you do breach the water source, immediately forbid the first door your miner runs through, which should be the door closest to the water source. Don't bother forbidding the other two. Link all three doors to three seperate levers and test the system. Close the door between the filling chamber and main farm area and open the door that leads to the water source. When the filling chamber is full, close the door to the water source, close the door leading to the farm, and open the door between the farm and filling chamber. The water should spread out and coat the entire farm in a thin layer of water. Then simply wait three or so years and you'll have your tower-caps, ready to cut down!

-'''Tower-caps''' are a type of mushroom-like [[subterranean]] [[tree]]. Once fully grown, they can be designated for [[wood cutting]] and produce tower-cap [[logs|log]]s. Tower-caps will grow ''only if'' you have discovered an [[underground]] [[river]] or [[underground pool]]. Such features can be located using the [[site finder]] and on the local view during embarkation, if the relevant [[init.txt|init]] and [[world generation]] parameters are set.
+== Tree Farms ==
-In order to ''prevent'' a tower-cap from growing (which you will want to do to prevent tower caps from blocking drainage floodgates), you must lay down [[road]]s, construct [[floor]]s or designate [[stockpile]]s.
+It is possible for tower caps to spontaneously grow in muddied subterranean areas <b>only if</b> you have discovered an underground [[river]] or underground pond. Unfortunately this is currently extremely difficult to do.
-As with normal trees, they take about 1 and a half years to fully grow.

-# If an underground river or pool has been discovered, tower-caps will start spontaneously growing in ''[[Irrigation|muddied]]'' subterranean areas (rock or soil). Tower caps will also start growing in any subterranean soil, so long as that tile has ''either'' soil walls on the z-level directly beneath it (intact soil, not mined out), ''or'' there is a muddied tile within 2 tiles on the same z-level.  Muddied soil has a denser production than dry soil.  (Note: it is unconfirmed whether tower caps will appear throughout the map or only in the same biome that the underground water is in.  See talk page for details.)
+The "arbitrary vegetation caps" comment is referring to the old limit of 200 trees growing by the [[cave river]] in the mud.
-# This basically means that if the underground area is irrigated, there is a '''much better chance''' of getting tower caps to grow there.
-# The distance or [[path]] to the underground river does not matter. Simply discovering an underground pool or river is enough. (does not work if you use reveal.exe)
-# It is thus possible to make a (big) safe underground chamber where your dwarves may harvest wood without exposing themselves to the dangers of the surface world.
-# Harvesting tower caps '''will''' anger the elves just like normal wood harvesting.

-Beware that young tower caps, like young trees, are fragile and will be quickly killed if repeatedly walked upon.
