The two S. hoffmanni's have molted again and both grew to 3.1 cm with this last molt.

S. hoffmanni #1 - male molted on 01/04/2014 (42 days after last molt)
S. hoffmanni #2 - female molted on 30/03/2014 (43 days after previous molt)

This shows the male's 4th molt interval increased as well, but the female's molt interval still one day longer. The male has caught up in size, catching up the 2 mm he was smaller than the female with previous molt.

Molts recorded :
S.hoffmanni #1 - molted 8/6/2014
S.hoffmanni #2 - molted 1/7/2014

Recent molt :
S,hoffmanni #1 - molted 10/10/2014
S.hoffmanni #2 - molted 17/10/2014

The last picture shows previous molt on the block paper used from the start. The square blocks are 1 cm and the little blocks inside the square is 2 mm. The first and second pictures show the T at 5 cm and the little horn starting to become visible.

Great job man. Its exactly what I imagined when we started this idea. Don't stop

Been a long time since the last molts, but they are both near to their next molt. Will be posting an update with pictures soon.

Seems I slipped up and never posted the last molt, which was on 7 December 2014.
Here is the photo of the hoffmanni shortly after that molt, measuring 6 cm.

The one Hoffmanni molted on 19 October 2015 and the growth is unbelievable, jumping from 6 cm to 10 cm ! This is the male and I am still waiting for the other one, expecting a molt any moment. Also note the color shown in the photo and the horn now seems diminished. I didn't wait for the T to harden up, but took the photo the day after it's molt, so the bent leg is just soft, not broken or damaged. If I waited longer the T becomes too mobile and would be hard to keep still on the graphic paper for an accurate measurement and photo. The male now has hooks and swollen pedipalps, confirming this to be it's ultimate molt.
