For starters, thank you for using my wifes picture for your profile. It was a nice photo shoot. lol.

Theraphosa need temperatures around, and as close to 23C - 24.5C as possible (73.4F - 76.1F). Nothing colder, nothing warmer.

This genus can produce in lower and in higher temperatures, however they will be infertile.

T. blondi burrow temps - 78.8F

T. apophysis burrow temps - 73.5F

I've produced stirmi once, egg sac is my profile pictures. 143 successful 2i. That was about 6-7 years ago, and since have not been able to.

I received two imported females recently, both dropped shortly after housing and keeping them at those temperatures. However, both sacs were bad.

I have a freshly molted proven female, and a penultimate male whos bald spot turned black the other day. So, I will be attempting them again shortly.

The main issue with breeding this species, is set up and dirt.

I use a mixture of peat moss, timberline top soil, a small amount of fine construction sand, and Sphagnum peat moss (that New Zealand brand).

For proper set up, I follow my good friend Ben Weber:

Key features play a roll in being a successful breeder, many of which I am still trying to figure out.

Even if you mimic these steps perfectly to a T, you need to consider your location, outside temperature and humidity, elevation, location of the tank in the house, circulation, windows, doors. You need to understand them, each person will find their own way with the same species. It takes time and patience. If you want to become a prolific breeder, you have to figure out your own personal methods, and what works best for you only. There will be many downers, such as bad sacs, eaten sacs, dead females, etc. Just don't give up, as the good will always outweigh the bad.

Best of luck to you. Let me know if you have any more questions my friend.
