B.angustum, B.albopilosum and B.vagans are from more moist areas so they should be kept in a little more humid conditions than the other Brachypelma species. Instead of mixing the damp vermiculite with dry as described above (in B. smithi), use the damp vermiculite alone. These species also grow much more quickly and can go from a 1" spiderling to maturity (4-6" depending on the species) in 2-3 years.
B. vagans can be kept similarly to B. smithi
