There are two kinds of Hermaphrodite cannabis plants.
True hermies or banana hermies.
A true hermie will show male and female preflowers at the node when it reaches sexual maturity.
A banana hermie will sprout male banana pollen pods from the buds late in flower. Depending on the strain maybe @ 7-8 weeks flowering
If your seeds came from a banana hermie pollination they are FEM seeds.
You will not see early male pods on this type of plant. Only late in flower will they show up. And not on 100% of the progeny.
