I know that Orks reproduce Asexually through spores and fungal deposits but how long does it take for an ork army to grow? Like say I leave 1 ork boy on a deserted planet. How long would it take for that 1 Ork to multiply into a huge Ork tribe?
more ork fight more they reproduce faster: a dead ork release more spore. but first a new planet need to develop an ork ecosistem with fungi squig etc etc.. so an ork alone will have some problem and need a lot of time because is a deseted planet: if on the planet there is something to fight... will be all faster.
I've heard that it takes approximatly 9 months (very original, guys) to a year for a spore to evolve into an Ork. Take it he isn't fighting anyone, it would take a lot longer for them to develop. In the meantime. Fungi, squigs and Gretchins would've already be full grown, wich will keep the lonely git busy till his fellow Boyz sprout. So yeah, wait a year or two and their will be a small tribe on that planet. Wait another year and the planet is infested with feral Orks. Ain't Dat interestin' !
