Since a tarantula is born, generally how long does it take for them to grow to a half an inch? I know it's different for every tarantula. I'm mainly wanting to know for the Grammostola genus.

Just to put my opinion, males and females can grow at different rates, not always will males grow faster, size wise. Yes, usually they will mature quicker but sometimes females can be larger due to genetics given that all other factors are equal. For instance, with my small "group" of P.pulcher I have 3 and the sexed female is growing much faster than the rest.
