==Description==
Provides artificial sunlight to grow crops.

Crops need [[Water]] and intermittent sunlight to grow. Without either of them, the plant will die.

[[Guide_(Farming)|Guide (Farming)]] provides additional info on how to setup farming with hydroponic tray.

The grow light provides light equivalent to 80% of solar intensity at earth distance to crops within its illumination pattern. Although multiple overlapping grow lights don't stack their effects, the effect of a grow light stacks with solar illumination, making the use of a greenhouse potentially worthwhile.
==Illumination pattern==

The Illumination pattern of the Grow Light has changed as of the [[Update v0.2.6085.26682|Respawn Update: Round Robin Community Starts (Update v0.2.6085.26682)]].

Lighting area is not a focused cone but a 8x7 small grid rectangle with the light being projected out 3 small grids from each side of the grow light.

Previous to this update, the lighting area was a 7x6 rectangle centred on the small [[grid]] of the grow light containing the power connection.

Although ceiling mounting is more logical with regard to real plants growing, it is worth noting that floor mounting will provide the same illumination pattern with no downside.

Ceiling mounting grow lights two large grids above planters will not provide adequate light to the planters.

[[File:Stationeers-grow-light-footprint-jan2026.png|frameless]]

Vertical illumination coverage extends for 5 small grid tiles, looking like this:

[[File:GrowLight topDown 2024.svg|frameless|wall-mount grow light coverage]]

==Wall Mounting vs Ceiling Mounting==
Ceiling mounting has a nominal coverage of 56 tiles, compared to 48 of wall mounting.

The presence of the light (and associated wiring) interferes with [[Harvie]] and [[LArRE]] placement. When either is expected to be used, wall mounting is more flexible then ceiling mounting. Note that Harvie requires space in two horizontal sides for chutes, so it can only harvest from trays with some separation between them; a Hydroponics LArRE does not have this limitation. It can also only be placed in a top-down arrangement, whereas LArRE can have stations interact with trays in any direction. Advanced builds can use this to stack up to 3 layers of trays on a single grow light while still retaining LArRE coverage for all plants.

If harvest is not needed (such as with ferns being used for oxygen production), trays can be placed so as to cover all available tiles within a tray. This allows up to 332 (8*7*6-4) trays to be illuminated by a single grow light.

Fire Extinguisher (Reusable)

2026-09-18T01:50:48Z

RA2lover: mention canister in slot is insulated and additional heat is only removed if above 20°C.

}}

{{Stationpedia|Requires a canister filled with any inert liquid to operate.}}

= Description =
The Fire Extinguisher (Reusable) is a handheld fire suppression tool. Unlike its predecessor the [[Fire Extinguisher]], it does not carry a fixed charge — instead it accepts a replaceable [[Liquid Canister]] or [[Liquid Canister (Smart)]] which can be refilled and swapped out.

Its canister slot is insulated, allowing safe long-term use of cryogenic inert liquids such as Liquid Nitrogen or Liquid Carbon Dioxide.

= Usage =
Equip the extinguisher and insert a liquid [[canister]] filled with a [[#Compatible liquids|compatible liquid]]. Activate to spray. While activated the extinguisher will extinguish fires, release its contents into atmosphere, remove 20kJ/tick of heat [[energy]] from the surrounding [[atmosphere]] (if above 20°C) and prevent reignition for five seconds after you stop spraying.

The canister must be at least 99% inert by content — spraying a canister containing [[oxygen]], [[fuel]], or any other reactive substance will not suppress the fire, and any liquid sprayed will still be released into the atmosphere.

== Spray duration ==
Spray rate is fixed at 0.25 liters per second regardless of canister type.

{| class="wikitable"
|-
! Canister !! Usable Capacity !! Spray Duration
|-
| [[Liquid Canister]] || ~12 L || ~48 seconds
|-
| [[Liquid Canister (Smart)]] || ~18 L || ~72 seconds
|}

== Compatible liquids ==
The following liquids are considered inert and will allow the extinguisher to suppress fires:
* [[Water]]
* [[Liquid Carbon Dioxide]]
* [[Liquid Nitrogen]]
* [[Liquid Pollutant]]
* [[Polluted Water]]
* [[Liquid Hydrochloric Acid]]
* [[Liquid Silanol]]
* [[Liquid Sodium Chloride]]

== Description ==
Portable device to extinguish fires or fires of small magnitude. It extingishes a single object from being on fire, making it useful in protecting small areas. However against a large scale fire it is recommended to vent the area.

== Use ==
Use left-click while in active hand while pointing at object to use.

It can be used to cool a [[room]] by pointing it an object and holding the click, the room temperature will drop fast making it perfect for cheap quick cooling on [[worlds]] like [[Venus]] where you start with one.

Dirty Ore

2026-09-18T01:25:17Z

RA2lover: /* Description */ mention dirty ore can be processed on a recycler

[[Category:Items]]

{{Itembox
| image =
| name = Dirty Ore
| createdwith = [[Deep Miner]] [[Rocket Miner]]
}}

== Description ==
Once a [[Deep Miner]] is inside bedrock it starts to produce Dirty Ore, which can be converted to regular ores using a [[Centrifuge]] or [[Combustion Centrifuge]], or into [[Reagent Mix]] at 50% efficiency using a [[Recycler]].

Alternatively, Dirty Ore can also be acquired using the [[Rocket Miner]], returning ore via rockets from space.

== Composition and Mining Regions ==
Dirty Ore will be converted by the ore-mix of the deep mining regions below the Deep Miner in a 1:1 ratio. The mining regions of a planet can be uncovered by using a rocket with a scanner-head.

== Notes ==
* Changed in 0.2.5903.26007 (terrain update) to have ore generation tied to regions.
* Added in v0.2.3619.17630 ("Deep Miner, Centrifuges, and Chutes", 2022-09-20).

Polluted Water

{{Stationpedia|Polluted water is a waste product from the use of [[Water]] in certain devices. It will freeze into [[Ice (Polluted Water)]] but boil into [[Water|Steam]].
A [[Water Purifier]] can be used to convert it back to [[Water]]}}

== Usage ==
Polluted Water is a byproduct of various machines such as when the player uses a [[shower]] as a means to raise a player's [[hygiene]]. Polluted water needs to be cleaned before it can be usable, either through a
[[Water Purifier|water purifier]] or by boiling the liquid into [[Water|Steam]].

Polluted Water has a specific heat of {{Gas/Property|Polluted Water|SpecificHeat}} J/mol*K. Because its source product, Water, and evaporation byproduct, Steam, have a higher specific heat of {{Gas/Property|Steam|SpecificHeat}} J/mol*K, the production of polluted water is a heat-deleting process which can be used for cooling.

== Sources ==
Polluted water can be obtained by using a [[Shower]] or [[Toilet]].

You can obtain polluted water by smelting [[Ice (Polluted Water)]] using a [[Furnace]] or crushing [[Ice (Polluted Water)]] in an [[Ice Crusher]]. Filtering is no longer required as the [[Furnace]] and [[Ice Crusher]] now contain separate outputs for liquids and gases. 

{| class="wikitable"

== History ==
Polluted water was added as part of the "Shelter in Space" update. It was added as a potential byproduct for raising the [[hygiene]] stat.

</onlyinclude>Outputs for plants and seeds are created at 29°C, and have their polluted water contents at exactly 5% of their produced alcohol. Biomass is the only exception to this rule, generating 10% of their produced alcohol as water.
Most [[plants]] benefit from being converted into [[Biomass]] first by processing them at a [[Recycler]] and [[Centrifuge]] before fermentation, although some exceptions exist. Corn and Watermelon produce more water and alcohol by being directly processed, while Blueberry, Pumpkin, Sugarcane, and Strawberry produce more alcohol (but not water) by being directly processed. If alcohol combustion byproducts are taken into account, they also produce more water by being directly procesed as well.

== Production Optimization ==
From the conversion rate table, Pareto-optimal plants are [[Switchgrass]] (highest harvest after conversion to biomass), [[Corn]] (Highest unprocessed harvest), and [[Watermelon]] (Highest output/h on max yield fertilizer). A fermenter takes 20 seconds to process an item for a total of 180 items/hour, potentially diminishing the effectiveness of switchgrass because the output of as little as 5 plants is enough to saturate a fermenter. However, [[Fertilizer]] production requirements introduce overhead.

Because Hay is counted as biomass instead of food, it contributes towards growth cycles when used in an [[Advanced Composter]]. As such, max yield fertilizer production is best done using Wheat as input stock for food.

An advanced composter consumes 180 items/hour and 1.2 kmols of water to produce 60 fertilizer, 3kmol of Nitrogen and 3kmol of Methane. Stacks of fertilizer with different properties can be merged to achieve a mixture of ratio properties after fertilizer production, but at this point no analysis has been made on whether this achieves better production per plot.

An alternative way to think about the problem is by considering the space taken by a fermenter. Each fermenter takes up 6-12 plots of space depending on layout. 4 fermenters fully loaded with biomass take up 48 plots + 17.76 (rounded to 18) plots for switchgrass growth. In order to be more efficient, corn/watermelon production would need to saturate a single fermenter (12 plots) with 180 crops/hour. This leaves 66 plots available for plants, which need to produce 180 crops/hour for a minimum of {{Overline|2.|72}} crops/hour, ruling out corn entirely as it can't achieve the equivalent production even with no area taken by fertilizer production. Unfertilized wheat can produce {{Overline|28.|4}} fertilizer/h for a total of 56 cycles.

Watermelon needs 50 plots, leaving 16 plots available for fertilizer production, which themselves need to produce at least 60 cycles of fertilizer/h (more if using fertilizer on fertilizer-producing plants). Mixing in a small amount of hay, fertilizer effectiveness can be increased, but not by enough to overcome a more compact fermenter arrangement as reducing space taken by each fermenter to ~9 plots is enough to nullify the advantage if power consumption is not priced in.
