Fem seed prob!

[marcus]

I have a problem. I've been growing many years know but have a problem with fem seeds!
I'm on my 4th grow all from fem seed and several stains but keep getting hermies!
I use a 2.2-1.2-2m tent. 6"extract and 5"intake. Light proof.light out temps don't do more than a 5° c drop. I use eleven ltr pots. Canna professional and bio biz organic nutes!
I'm baffled as they r grown text book but why are my fems hermieing?
Worst is I don't know until dry then notice the seeds and just not good but the effect is on!

Fem lines that have not been tested or selected for intersex can be trouble, sadly not many breeders do much progeny testing.
