a tiny bit hot maybe.
30-35C (86-90F) is probably ideal.
But with Abyssinian Banana (Ensete Ventricosum) which is not a true banana (Musa). you can't go too far wrong. I put 15 in on 07-13-2007 and have 8 from 15 seeds so far.
As they germinate put them up into 75mm(3") pots, in good compost and water well. I put a ziplok plastic bag over the top of the pot and hold in place with a rubber band to create a humid environment. the growth rate is unbelievable. stand back...pot on as neccessary.
enjoy
