At least two years I would say. It's taking a whole year for my fastest growing ones to reach just 4 inches (6 instar).Out of curiosity, how long do they take to mature? I assume slow but are we talking brachypelma slow or like grammostola slow, if we can relate it to Ts.
Agreed. I would choose babies or juveniles, if available, over adults ever time.You must not be very old, you get older and 2 years goes by pretty fast. My Aphonopelma moderatum tarantulas are maturing this year and they took 9 years, it sure didn't seem that long. I'm guessing 2-4 years for the dictators to mature. But why wait to buy mature scorpions? You have them for less time, they will die of old age sooner waiting for them to mature to buy. Hey Mathias, are you keeping yours together, had good luck with it? I've had bad experiences with that, they are more aggro than emps. I kept three babies I had earlier together, two behaved as if they had been stung and died, the bigger one is molted and healthy.
