The growth vat is a building added by the Biotech DLC. It allows the gestation and accelerated aging of babies and children.

Acquisition

Growth vats can be constructed once the Growth vats research project has been completed. Each requires 150 Steel, 4 Componentss and 8,000 ticks (2.22 mins) of work.

Summary

Growth vats take a constant 200 W of power as well as nutrition. Both raw and processed foods, including nutrient paste, can be inserted inside. 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.

If there's no power or nutrition, the being inside will enter Biostarvation, which increases in severity by 50% per day starved, and kills at 100% severity (or 2 days). Biostarvation also increases food consumption (by +10%), lasting for 5 days per 1 day starved.

Baby creation

Growth vats be used to grow an embryo in 9 days, twice as fast as natural pregnancy, and regardless of Fertility (as long as it's above 0%). This comes without risk to the mother, but the baby can still arrive sick.

Children

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, and children will not gain growth points.^[??] Every 3 days inside the vat, they will gain a small amount of skill, even if a baby. Parents will have a −4 My child is in a growth vat moodlet while their kid is inside. However, if the Ideology DLC is installed, ideoligions can have the "Growth vats: Preferred" precept, which gives pawns a +2 mood boost for having their own child in a growth vat, or a −3 "My child is not in a growth vat" moodlet. Having this precept also gives pawns a −3 "No growth vats" moodlet if the colony has no growth vats and expectations are moderate or higher.

Analysis

Babies can be placed in the growth vat to speed up reaching toddler age. There are no apparent ill effects on the baby, and they even train an age-3 valid skill (Shooting, Melee, Social).^{[Not extensively checked?]} However, parents gain a -4 moodlet, and it negates the mood buffs from having a happy baby in the colony.

Even if a child is at growth tier 8, they lose out on the skill training provided by the Lesson learning type. Meanwhile, aging a teen (13-17) to 18 is usually worthwhile - pawns under 18 have workspeed penalties.

Nutrition

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#Manually producing meals for how you can stockpile nutrient paste.

Without nutrient paste researched, baby food is the next best way to prepare vegetables. Simple meals are the next best way to prepare other food items.

There are no penalties to anyone for using insect meat, already-butchered human meat, or other usually undesirable food items in a vat.
