Eh mrberrys!
Okay the first question to ask is, HOW did they get to be hermied?
Are you aware of any stress that you put your plants through to make them grow sax?
Because if the answer is yes, it's actually a GOOD thing.
See, the herm trait is heritable, so the offspring will behave silimarly under similar conditions. If you fix the problem you had that cuased herms in the first place, you might get none at all the next time, and have plain ol females.
But if they went herm for no apparent reason, or you can't fix whatever problem you had, your results will be similar next time.
As for 90% females, yup, but it's even higher, closer to 99%.
