Not too scientific I'm afraid. For this and earlier clutches I merely placed them in large sealed deli cups on a mixture of vermiculite and powdered cocoa husk fiber on a 1:1 moisture mix. They incubated on the bottom of a Boiga Cynodon cage governed by a Herpstat thermometer at a somewhat constant 83F. One clutch was merely placed up high on a shelf in my snake room which is our converted garage.....much more variable temps....from 80F-84F. I'm sorta moving away from a static incubation regimen as far as temps go for Colubrids.

All my Zonata eggs (3 clutches of 6 ea.) are incubating at "room" temps on the floor of the same snake room/garage and temps range from 76F-82F. Never had a problem with them at all.
