I found 70cm x 35cm x 20cm. Those should be enough, right?
I'm not sure about belly or back heat... I've found mixed reviews about both...
What's your angle?
Belly heat has less heat loss than back heat, as far as how much flexwatt you want a strip that is as wide as your tubs and 4 inches (10.16 cm) wide will be enough.
Even with an enclosed rack I highly recommend belly heat for adults, hatchling on the other end since the tubs are much smaller do well with back heat.
As for the tub being big enough, standard for adult females is 92 cm x 41 cm x 15.25 cm
