Yes, I noticed that post slipped in while I was typing rather slowly- sorry to be slightly repetitive. What was the state of the two sacs produced? Were the sacs of average size with average survival rates?To answer your question in part reference the post above yours. (Post #20)
Now to add to it, my GBB is 3yrs in my care and has produced 2 sacs. She is just dandy. Nothing out of the ordinary.
It's fascinating that you achieved that kind of growth rate with a G. pulchra.
