Editing 40d:Tower-cap

'''Tower-caps''' are a type of mushroom-like [[subterranean]] [[tree]]. Once fully grown, they can be designated for [[wood cutting]] and produce tower-cap [[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]] and [[world generation]] parameters are set. 

As with normal trees, they take about 1 and a half years to fully grow.

== Underground tree farms ==

1: If an underground river or pool, has been discovered tower-caps will start spontaneously growing in ''[[Irrigation|muddied]]'' subterranean areas (rock or soil), or any subterranean soil (disputed; unmuddied soil may require soil walls on the z-level below for growth; see talk page for details), though muddied soil has a denser production than dry soil.

2: This basically means that if the underground area is irrigated, there is a '''much better chance''' of getting tower caps to grow there

3: 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)

4: 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.

5: Harvesting tower caps will anger the elves just like normal wood harvesting.

On the subject of spawning tower-caps, [[Toady]] said:
<blockquote>''Right now, you can't plant tower-caps 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.<sup>1</sup> Later, you should be able to plant them. There are no arbitrary vegetation caps now<sup>2</sup>.''</blockquote>
::<sup>1: Note that it ''is'' working and that underground rivers are not that rare any more.</sup>
::<sup>2: The "arbitrary vegetation caps" comment is referring to the old limit of 200 tower caps growing by the [[cave river]] in the [[mud]].</sup>


To design a tower-cap "farm", refer also to the [[Irrigation#Easier.2C_safer_irrigation|irrigation]] article.

Beware that young tower caps, like young [[tree]]s, are fragile and will be quickly killed if repeatedly walked upon.
