How long did they typically take to molt to maturity, from what size did ya get em, and all that fun stuff.

I got a sling a couple months ago, it's molted once for me, and is still a sling. Not showing any colors yet, of course, pretty much a gray/brown spider. It's very skittish and reclusive, have only seen a handful of times. Appetite is so-so, preferring superworm pieces vs. crickets.
