Does that mean you have a B. vagans and G. rosea egg cases?
If that be the case please share your breeding experience.
Nope, I only have a vagans egg sack, rosea is gravid though and should drop in about 2 weeks I'm hoping. I kept it simple, mated them, Super D came to my house and suspected my vagans was gravid so I moved her to the front of the panel heater to raise the temps to about 30, and fed her A LOT! Still left her with a water bowl and a couple of weeks later she dropped. What I'm doing now is wetting one side of the tank, took the water bowl out and put a heat pad on the side where I am wetting the substrate, the other side I leave dry, this raises the humidity to around 90% without wetting the egg sack. Now I just hold thumbs and pray for them to be alive when I pull the sack
With the rosea I mated her a few times ( by the way I'm not good with record keeping or dates ) Then she started eating a lot and became more aggressive so I moved her in front of the heater still with a water bowl and I'v just been feeding her a lot as well. I plan to wet the substrate and get the humidity up like with the vagans. O and I have been keeping her quite dry besides the water bowl because of her natural habitat. Generally spiders mate at the end of winter/spring and then fall gravid and drop in summer (I think) so I try to replicate these environments.
My friend just bred A. avicularia and also had semi success, mated her a few times then she actually dropped sooner than he expected, so when she did drop he flooded the tank and raised the temps for the egg sack.
By the way the mating were done in winter, so the temps sometimes dropped to below 20, but in front of the heater it is about 30. Can I just say that these are apparently easy spiders to breed and I'm calling this beginners luck. I did talk to a lot of people about breeding and that is where I got the basics from, but as Cerat said you do learn to read your spiders and experience does play a part in the process.
I hope this helps

I know it is probably what everyone else told you to do but it seems to work pretty well.
