I've got a very tiny (0.8cm) B. vagans at the moment, so I'll definitely start of this project with it.

I also have a 1.5cm N. Chromatus. I'll spend some time on this tonight and will hopefully be able to post it soon.

Brilliant Idea! I have been keeping notes on my T's like size, sex, date of molts, etc. and now I can share their progress.

P. Striata slings are about 3cm already, but they'll do for a start.

Just my 2c on this project:

What would be a great project would be to get 2 slings, preferably sac mates and hopefully ending up the same sex, and document their individual growth rates. To make it really interesting you could then keep one at ambient temp and humidity and on a regular 3 weekly feeding schedule whereas the other test subject would be temp and humidity controlled as per the species husbandry requirements and power fed every 1-2 weeks.
This growth comparison would be more interesting than seeing individual random spider growth rates which, in my opinion, may end up being a bit boring considering the time between molts may be months. The only way this would interest me would be if the log kept information like:
When the T was fed,
When it rejected food,
How long it closes itself off pre-molt,
How long you waiting post molt before feeding,
Temp and humidity(accuracy would be quite important)

These factors all have the potential to affect the growthrate. Perhaps even your location could be a factor, Bloemfontein vs Durban for example.
I will look at maybe doing this myself, what I basically mean is maybe we can agree on a template on some form to keep all the various factors standard for comparison purposes. What do you think?

I like that idea Steven. The more information associated with this chart, the more interesting it would be and the more comparisons, the more valuable it will be as a care sheet for the specific species. Time passed in fasting and hermit stages will be particularly interesting.

My G rosea was 2cm and went 4 months with no food, wouldnt eat. then molted twice in 2 weeks with 1 cricket in between molts. Now been 2 months with no eating.
this sort of info would be crucial in a "study" like this I believe.

That's very unusual, even for G.rosea. That's why your suggestion of charting two of the same species is good. It can be compared to other growth charts to find "the rule" and document the exceptions.
