I thought we could compile some molt records to use as a reference for growth rates. I have records for 15 species and will add the rest very soon. Feel free to share yours as well.

Neat. I'll come back and include mine, though none are mature yet.
I just wanted to add that you should also note how they were generally fed (powerfed, more than once a week, once a week, whenever I felt like it, etc.), as without that, the dates don't really mean much.

EDIT:

And general temps too!

i have records of all the molts i have for all the slings i have. I don't have enough time in the hobby to have significant records, but i've been thinking of starting a newer more detailed record of them such as growth rate, feeding, molt times and a few other details. I just haven't set it up just yet. i also got a few new 3rd and 5th instars so i'm still in the middle of naming and working on their records.

I have detailed molt records but my T's generally grow pretty quick. I'm interested in seeing the OP's records posted for comparison.

I don't have a set feeding schedule... I feed them according to abdomen size (plump but not over fed) but generally I feed slings 1 cricket/wk and sub-adults and adults get 2-3/wk. I set my temp according to the seasons right now night temp is around 72 degrees and day temp is 80 degrees (humidity I set according to the species specific needs). I get care information from Arachnopets.

I dont have a set feeding schedule either. I'll feed them till they're fat (not obese though) for the most part. They get crickets until I can get them to consistently take dubias, which varies from spider to spider. As far as temps, I keep them at 80-85, roughly, until they get to about 2.5 inches after which they're kept at room temps, probably about 68-78 depending on the time of year and day. Humidity-wise, I mist more or less depending on the specific T's requirements.
