'''Plants''' are passive, flammable objects available in numerous species of different appearance, growth rate, lifespan, '''fertility''' requirements, and biome. Plants are generally passable, minifiable, provide no cover, and are not susceptible to Sharp or Blunt damage (except trees, cacti, and bushes.) All plants can be destroyed by [[Fire]], [[Work#Plant_cut|cutting]], a [[Defoliator ship]], or being consumed by an animal.
 
−
Plants may spontaneously grow in available tiles or can be cultivated by colonists in [[growing zone]]s or [[hydroponics basin]]s. With adequate time and environmental conditions, plants will age into a '''mature''' lifestage when they can be '''harvested''' by colonists assigned to [[Work#Grow|Grow]] work.
 
  
−
Plants are essential to producing [[food]], [[textile]]s, feed for [[animals]], [[dye]], [[wood]], [[chemfuel]], [[drug]]s, and [[medicine]].

'''Plants''' come in varieties that are either cultivated or grow wild. Cultivated plants are planted by colonists in a [[growing zone]] or a [[hydroponics basin]], mainly for food. Wild plants grow naturally throughout the map. Some wild plants spread themselves via seeds. Animals mostly graze on wild plants but will happily eat cultivated crops as well, including tamed animals. Since Alpha 17, they leave [[filth|ash]] on the ground when burnt.

The medium used to grow the plants in matters for both for growth speed and if growing a plant is even possible in any given spot.
−
Fertility is a measure of a location's efficacy for growing plants. Most plants have a Fertility requirement of at least 50% (except trees at a measly 30% Fertility). Plant growth speed is also positively correlated to soil Fertility. However, fertility does ''not'' affect the harvested yield from a plant, just the time to mature to that yield. Different [[terrain]]s or growing apparatuses have different fertilities.  
 
  
 +
Most plants have a Fertiltiy requirement of at least 50%. However, most Trees come out with a measily 30% Fertility.
  
 +
Most plants have a <fertilityFactorGrowthRate>, which is used to determine how "picky" a plant is about how fertile its terrain needs to be. Ingame this is also denoted as "Fertility sensitivity". A plant with a <fertilityFactorGrowthRate> of 0 will not care if it is planted on fertile soil or sand; it will grow at the same rate on any terrain tile that will accept its roots. In contrast, a plant with a <fertilityFactorGrowthRate> of 1 will not grow so well if it is planted on anything less fertile than standard soil.

'''Note''': Beyond 100% Fertility, high Fertiltiy Sensitivity becomes a bonus rather than a penalty. For such cases highly sensitive plants are preferable.

For normal growth rate, plants require [[temperature]] between {{Temperature|10}} and {{Temperature|42}}. Plant growth rate drops by 10.0% for each degree Celsius below {{Temperature|10}}, and by 6.25% for each degree above {{Temperature|42}}. The plant's info window will show 'Non-ideal temperature. Temperature growth multiplier: #%'. Plants will not grow when the temperature falls below {{Temperature|0}} or rises above {{Temperature|58}}. The plant's info window will show 'Non-ideal temperature. Not growing.' If the temperature drops below {{Temperature|-10}}, the plant will either die or lose its leaves, depending on its type. This is obvious on trees, because it shows a new graphic with no leaves on it, but it actually applies to all wild(?) plants, including grasses. Leafless plants are inedible by animals. This may cause problems to inexperienced players, as it's unrealistic and the game doesn't give a hint on why colony's animals stop grazing and starve, the plants seem perfectly normal upon close examination. It takes 24 hours to regrow leaves after the temperature rises back above {{Temperature|-2}}, the plants cannot grow before then, despite possibly high enough temperature.

−
If they are not harvested or eaten, plants will eventually die. The [[Menus#Messages 2|message]] will be named ''<plant> died from rotting''. The counting of their lifetime starts when the plant is sown/spawned. Since plants only grow during certain hours, and growth rate varies greatly under different circumstances, it is possible for a plant to die before it reaches full maturity or even while still on the initial progress. A plant will also die from rotting if it is completely deprived of light - for example, if a roof is built over it.

There are no clear categories of plants provided by the game. For the purpose of easier comparison, plants can be split in the following categories. Note that many plants fall in more than one category.
 
−
* '''[[Wild plants]]''' are plants that can't be planted by the player.
 
−
* '''[[Decorative plants]]''' are plants that can be planted by the player and which main purpose is to add [[Beauty]] to a room or area.
 
−
* '''[[Trees]]''' are plants that yield wood or have "tree" in their name.
 
−
* '''[[Domesticated plants]]''' are plants that can be planted by the player and yield something else than wood.
 
−
* '''Food plants''' are plants that yield food.
 
−
* '''Resource plants''' are plants that yield something else than food and wood.

The yield of plants with products depends on four factors:
 
−
# The base yield of the plant
 
−
# The maturity of the plant. Plants that are harvested at the first possible moment (at growth 65%) will only grant half of the total normal yield; this scales linearly towards full harvest as the growth percentage increases. This gives a slight penalty to early harvests.
 
−
# The health of the plant. Damaged plants will lose up to half of their yield. A plant at 50% health will lose 25% of the yield.
 
−
# The [[Plant Harvest Yield]] of the harvesting pawn which acts as a scalar on the resulting number.
 
−
# The [[AI Storytellers#Economy|Harvest Yield]] storyteller variable - note that [[Difficulty]] settings change variable even if a custom difficulty is not selected.
 
  
−
As plant harvest yield increases with [[Skills#Plants|Plants skill]], pawns with the highest skills should ideally be used to harvest plants, while any pawn can be used to sow them.

'''Downsides:'''
 
'''Downsides:'''
−
* Trees cannot be planted in greenhouses

* Needs tiles that can support building walls to support the roof, which is difficult in swamp biomes
−
* High energy costs for maintaining sun lamps
+
* Sun lamps require incredible amounts of power during the day: 1-2 solar generators worth of production for the entirety of the plant's non-rest cycle
−
* Requires electricity research to unlock
+
* Energy production to power sun lamps can cost incredible amounts of resources, both upfront and in maintenance/refueling
 +
* Sun lamps are sensitive to power outages, which usually won't kill in ground greenhouse crops unless the temperature dips low enough outside to affect plants inside
 +
* May require research to unlock

==== Open roof greenhouses ====
+
===Hydroponics Bay===
−
Only indoor rooms can control temperature, however any room is considered indoors so long as less than 1/4 of the tiles are unroofed, up to a limit of 300 unroofed tiles. Though unroofed sections increase the rate of temperature equalization significantly, this allows the creation of greenhouses that can be used to grow trees, which cannot usually be grown under [[roof]]s, or even without sun lamps. 
 
  
−
These are constructed like most greenhouses, but with the [[remove roof area]] order used to remove 1 tile fewer than 1/4 of the roof. If for growing trees, these removed areas should be spaced 1 tile away from each other gap both horizontally and vertically, as trees cannot be sown next to each other. For growing traditional crops without a sun lamp, this should all be concentrated in one area to limit time spent traveling from place to place while sowing and harvesting.
+
Hydroponics is the knowledge of growing plants without soil, using a nutrients dissolved in a water bath. In game it requires research to unlock and the building of one or more Hydroponics basins. These basins will override any growing zone they are placed on top of.
−
 
 
−
Due to the costs of controlling the temperature, using this strategy to avoid the cost of sun lamps may or may not break even depending on the biome and the heating or cooling required.  In cold biomes, combination with a [[steam geyser]] can significantly reduce heating costs, making this strategy much more viable regardless of the intent. If using [[campfire]]s to heat the greenhouse, they should be placed in the roofed areas to prevent additional fuel usage during inclement [[weather]].  
 
  
 
'''Upsides:'''
 
'''Upsides:'''
−
* Does not require sun lamps or even electricity
+
* Basins provide a effective fertility of 280, easily doubling growth speed of many plants
−
* Can support trees, including [[cocoa tree]]s.
 
−
** When used for trees, no larger than is necessary as trees can't be planted adjacent to each other anyway.
 
−
** Forces trees to be sown perfectly spaced without having to micromanage it, improving yields/area
 
−
* Easy to convert to and from more traditional greenhouses
 
−
 
 
−
'''Downsides:'''
 
−
* Needs significantly more heating/cooling
 
−
* 4x larger for the same volume of non-tree greenhouse space
 
−
* Slow and/or difficult to adapt to changing weather conditions.
 
−
* Net wood-negative when using campfires to grow trees.
 
−
 
 
−
===Hydroponics basin===
 
−
Hydroponics allows plants to grow without soil by using nutrients dissolved in a water bath. In-game, it requires research to unlock and the construction of one or more Hydroponics basins. These basins will override any growing zone they are placed on top of.

* Can be combined with in ground growing, maximizing the coverage of sun lamps in biomes with little fertile ground, like Ice Sheet
 +
* Only minor additional power cost for the basins (compared to the power hungry sunlamp)
 +
* Full flooring can be used to speed up movement including passing through, harvesting and sowing speed
  
 
'''Downsides:'''
 
'''Downsides:'''
−
* Building a sun lamp and 24 basins (the maximum amount of basins that can fit within a sun lamp's radius of light) requires a huge resource and power commitment, requiring 4580 watts, 1720 steel, and 24 components.
+
* A maximum of 24 hydroponics bays can be lit by a single sun lamp
−
* If the basin loses power or breaks down, the plants within will begin taking rotting damage which will kill most plants within 8 hours unless power is restored or the basin is repaired.  If the power stays off for an extended amount of time or the basin cannot be repaired, then harvesting the plants as soon as possible is recommended.
+
* Building the full 24 hydroponics bays under the coverage of one sun lamp requires incredible amounts of resources
−
* A power outage including [[Events#Solar flare|solar flares]] can wipe all of your hydroponic crops, requiring extensive replanting and usually disrupting food production.
+
* If the basin is disabled in any way including power outages or breaking, the plants will die within an in-game hour, unless it can be repaired immediately.  If not, manually harvest ASAP
−
* There are fewer options for growing crops within hydroponics basins.
+
* A power outage including [[Events#Solar flare|solar flares]] will wipe out the entire plant stock in all basins, requiring extensive replanting and usually disrupting food production
−
 
+
* Only a select few crops can be grown in the basins, usually ones with growth times under 10 days
−
== Version history ==
 
−
* [[Version/0.10.785|0.10.785]] - Rebalanced and reformatted plant ecology tunings to lengthen crop cycles and slow wild plant spread. Reworked plant growth in relation to light levels so plants can still grow slowly in dim light (e.g. tundra summers).
 
−
* Beta 19/1.0 - All non-tree sowable crops yield 20% less when harvested and take 10% longer to sow.
