Without male plants the seed came from a male flower on one of your females. The resulting seeds will be female. If the plant was pollinated by itself it will be an s1. If pollinated by another strain it will be a female cross of the 2.
If the genetics hermied due to environment, there is no increased chance of hermaphrodite plants in the seed.
If the genetics had the Hermie trait regardless then you have the same chance as you did with the original seed of producing male flowers.
Grow it out!
