I've got it all researched, but the storyteller is being an asshole and not giving me any female colonists to actually do any bioengineering (need babies; can't make babies without women). I have a colony full of men that all hate each other. Half of them are bi or gay, too.

But at least I know the growth vats work great because I also set the child age rate to x100 (regular age speed for colonists) so a lot of the recruits are between 5 and 10 and have to be aged to be useful. Age 'em up to 13 and then use bioscultpers to keep them there forever :D
