Hey,
So I bought several G. rosea juveniles from LLL reptiles and co. most of them have molted at least once by now but I'm still thinking that some of them are not mature yet. I have been able to sex them using the molts but don't know if that is indicative of sexual maturity. I know about pedipalp bulbs/hooks as well so the males are not a problem. My question is how many molts are normal from sling to adult? and how will I know when the females are mature adults? Also, if anyone has bought juveniles from this seller before that can tell me how long it took for their spider to mature that would be great!
Thanks!

p.s. I can provide pics if needed.

Varies from spider to spider. And sex.

Don't buy from LLL, they are reptile people. Not arachnid people. Often sending the wrong species and sex.

It can be...the spermatheca will darken when a female is mature.

That's ONLY once a male males its final molt...only MMs have them.
My question is how many molts are normal from sling to adult
As venom said, its totally variant.

They grow crazy slow, since juvie is a purely subjective term, we don't really know the size of these ts...but if theyre say, 2"...it could be a decade before a female matures. Don't plan on having them mature anytime soon unless theyre already pretty large.....what's the DLS?

DLS= Diagonal Leg Span

the 3" ones are many years away....the 4" ones are probably very close to maturity.

again they are varied, but the smallest (those that haven't molted) are probably at least 3 in. and the largest females are 4 in probably.
Well neither of those spiders are really juveniles. The 4" one is most likely a sexually mature adult, don't expect it to get much bigger.

Both of your spiders are already easily older than five years. Most likely quite a bit more.

Is there any outward sign of maturity other then size for females? I know in some true spiders mature females will have a dark spot on their epigastric furrow. wondering if tarantulas are the same?

Nope, there are no outward signs. The general guide is that the spider is sexually mature at 75% of its max size. What @cold blood brought up is the only sure-fire way to check for sexual maturity in females:

It can be...the spermatheca will darken when a female is mature.

For some of them it seems like they won't get there until Ragnarok.

This thread actually brings up another point in that the maximum size of a fully grown adult is often exaggerated (for a lot of species not just this one).
