While hosting a human, growth vats require a constant 200W of [[power]] as well as [[nutrition]]. Both [[raw food|raw]] and processed foods, including [[nutrient paste meal|nutrient paste]] and [[hay]], can be inserted. None of the usual mood bonuses or maluses from different food types, such as from [[human meat]], are applied. Hosting an embryo costs 6 [[nutrition]] per day and aging a child costs 3 nutrition per day. The vat's contents can be ejected immediately by the player by canceling vat growth; if it was an embryo, it will be destroyed. When no pawn is inside, the power consumption reduces to 80W

If the vat has no power or nutrition, the being inside will enter [[bio-starvation]], increasing in severity by 50% per day starved, and decreasing 10% per day properly supplied or spent outside the vat. Bio-starvation increases nutrition consumption in a vat by {{Bad|+10%}} at all severities, and [[Death|kills]] at 100%. If a bio-starved pawn leaves the vat, a number of status effects will be applied to them. See [[bio-starvation]] for a full list.

Colonists under 18 can also have their aging sped up by 20x, i.e., it takes 3 days to age 1 year. This ignores the default 4x aging multiplier for [[babies]] and [[children]], so a vat is 5x faster than that. While in the vat, a pawn's needs are frozen like in [[cryptosleep casket|cryptosleep]], and children will not gain growth points. Every 3 days that a baby or child is in the vat, they'll received 8000 experience (before passions or other multipliers) towards a random skill.  The skill selected is entirely random and does not prefer passions, though it will ignore skills that are disabled due to backstory or traits.  The experience ignores the daily limit of XP to a skill and is not affected by global learning rate (for example, the Fast Learner trait), but is modified by the child's current passion level in the skill chosen.

As a child spends a maximum of 54 days inside a growth vat from birth to age 18, a child gains a maximum of 18 of these experience bonuses, for a total of 144,000 pre-passion experience.  If distributed evenly across skills, a child can expect to see an average of 12,000 experience per skill before passions.  Ignoring passions that are changed at growth moments, this average XP would cause a no-passion skill to reach level 2, a regular passion skill level 4, and a burning passion skill level 5.  Exact distribution will vary randomly, and passions can be altered at growth moments, affecting this gain rate.  Overall, however, it is very unlikely for any given skill to reach more than level 8 even with a burning passion in it from the start. A child grown entirely within a vat will have no passions and 3 random traits.

In these cases, vats exchange time for the cost of nutrition and power. Each vat doesn't consume much power, while nutrition can usually be solved by simply growing more food. For reference, growing a child is just under 2 colonists' worth of food. An embryo is roughly equal to 4 colonists for the duration, consuming 60 [[simple meal]]s over the 9 days.

On the other hand, completely vatgrowing ''baseliners'' will have them end up being fairly weak pawns. A vatgrown child will end up with 0 passions, very weak skills, and 3 random [[trait]]s - a [[Events#Wanderer_joins|wanderer]] or just about any [[prisoner]] recruit is likely to just be ''better'', without consuming nearly as much nutrition. Regardless, vats will ignore the game's natural population curve, and will always be able to fight, haul, and clean competently. Of these, hauling and cleaning can be accomplished with [[lifter]]s and [[cleansweeper]]s, both which are cheap and very early on the [[mechanitor]] progression path. However, the math becomes less aggressive when one considers available options to increase nutrition efficiency of an embryo. Embryos can be carried by permanent prisoners who can be fed Nutrient Paste directly, and given custom [[Xenogerm|Xenogerms]] to drastically reduce their nutrition requirements.

Notice that vatgrowing baseliners will end up with poor results. With the [[gene]] system, it is entirely viable to create a vatgrown army, either with in-game [[xenogerm|gene modding]], or a player-created [[xenotype]]. The genetics system is a natural fit to growth vats.

Notice that vatgrowing baseliners will end up with poor results. With the [[gene]] system, it is entirely viable to create a vatgrown army, either with in-game [[xenogerm|gene modding]], or a player-created [[xenotype]]. These two mechanics fit incredibly well with each other.
  
 
For example, a simple [[xenogerm]] consisting of [[Genes#Great Shooting|Great Shooting]] / [[Genes#Drugs|Psychite Dependency]] / [[Genes#Psychically deaf|Psychically deaf]] will create a pawn with a passion and 8 free levels of Shooting, easy mood regulation through [[yayo]], and a hunger rate of only 70%. An amazing [[Roles#Shooting specialist|Shooting Specialist]].{{IdeologyIcon}} Lategame colonies can form dozens of vatgrown soldiers with this xenogerm, completely blasting through the game's intended population level, only being limited by growing space. This becomes even more powerful when considering xenotypes you can create at the start of the game, which can be min-maxed as much as you'd like.

While [[raw food]] can be put into the dispenser, virtually any means of cooking a meal gives more [[nutrition]] per food item. The absolute best way to prepare food is the [[nutrient paste meal]], which triples nutrition. However, colonists won't automatically dispense nutrient paste for a growth vat; they will only haul meals on the floor to it. See [[Nutrient paste dispenser#Manually producing meals|Nutrient paste#Manually producing meals]] for how you can stockpile nutrient paste.

Basically, an organ harvesting operation using a Cannibalism: Acceptable and Organ Use: Acceptable [[ideoligion]]{{IdeologyIcon}}, with a psychopath/prisoner mother and psychopath/[[slave]]{{IdeologyIcon}} father (male prisoners cannot fertilize [[embryo]]s and slaves are cheap and disposable) is highly profitable, and comes with no mood downsides. You can give the child [[EMP grenade]]s and make them "guilty", removing the moodlet for colonist death. All that's needed is a good doctor, some medicine, and preferably a [[hospital bed]]. Without a pro-organ ideoligion, mood impacts start to matter more, but... it can still be profitable.

=== Grow soldiers ===
 
−
Growth vat can be used to create an army of genetically-modified soldiers. All you need is (the best strategy):
 
−
* Prisoners. A lot of them. Used to obtain embryos. Optional, but strongly recommended. Try to use different men and women for every embryo: your soldier will not have debuff "my brother died". Don't use your colonists, or they will have a trait "my son died X3" after every battle.
 
−
* Genetic lab. Implant at least strong shooting and melee to your army.
 
−
* Powerful production facility to give your army at least some equipment.
 
−
* Crypto caskets. For peaceful time.
 
−
 
 
−
=== Food ===
 
−
If you have no other source of Animal Protein this is your best bet aside from buying and raiding. To efficiently use growth vats as a food source you must do he following:
 
−
* When creating your [[Ideoligion]] {{IdeologyIcon}}, choose the [[Cannibal]] {{IdeologyIcon}} meme, for obvious reasons. You should also strongly consider using the "Growth Vats: Essential" Precept (henceforth to be referred to as "the Precept" or "P"), as it increases the throughput of your growth vats by a considerable amount.
 
−
* To get the Embryos, you'll need to get a lot of female Prisoners and male Slaves. Consider stockpiling fertilized Ova and disposing of all the affected Slaves and Prisoners. You'll have a Grace window of at least 52 days before the first Moodlets start coming in.
 
−
* The Setup
 
−
** To maintain one Baseline Colonist you'll need at least 4 (3.34 w/P) growth vats constantly running.
 
−
** One ideal [[hydroponics basin]] setup (24 basins growing [[rice]]) converted into [[nutrient paste meal]]s can sustain up to 12.6 (12.3 w/P) Growth Vats.
 
−
** To efficiently Butcher and Cook the Subjects you'll also need a Pawn with a cooking skill of at least 10 and 100% manipulation (such as a [[Fabricor]])
 
−
** Additionally this method supplies [[human leather]] and organs, though harvesting the latter will reduce the amount of meat gained.
 
−
** You can also use the subject pawns for new fertilized ova.
 
−
For optimal distribution, 91.5% (90% w/P, always round up when applying) of your hydroponics basins should be dedicated to making rice for nutrient paste for the vats, the rest should be making rice for cooking.
 
−
Two sets of 24 hydroponic basins and 22 growth vats can grow enough Nutrition to produce roughly 10 (11.5 w/P) [[fine meal]]s per day, which is enough to support 5 colonists, so this is clearly not very efficient. The construction and maintenance cost of the hydroponic basins and growth vats are also considerable.
