Fast bananas are from how you choose the sucessor pup..............I think...............
If you manage the Mat...............left just one pup per plant................the bunch come quick.....................
This Nanner is the fast variety I planted here.....................and it produces ten to dozen pups....................like crazy...................
But I just left one................the chosen pup...............

.
It grows very fast and produces the bunch in a period of a years...............
plus few months to the buch became ripe..............
This is the Nanner Mat..............
Another fast Bananas that I have is Prayng Hands...............but the Nanner is faster....................even the pups sprout and grows faster....................
But Praying Hands is a fast banana too..................
This is my Praying Hands.................
And its bunch...........
But..............I believe that pup pruning.........is the best way to get the bunch earlier...............
