Re: What seeds have germinated for you?
From what I have heard, Gibberilic Acid can also do harm if you use it in wrong amounts. Plants can grow thin and weakly in strange directions and forms. When GA was first observed in rice-plants, the asians referred to it as "Foolish rice".
I don't know how it affects bananas though. And I am all for experimenting.
As far as I am concerned with growing musa from seed, a large amount of seed and fluctuating temps seem to be fine to produce many plants.
