Odd, I have heard a lot of Barney's Farm seeds showing male flowers.
If it is feminized, it can not be a real hermaphrodite.
It showed male flowers most likely due to too much feeding. That is the most common way of stressing a plant.
This "hermie gene" people talk about does not exist in the way people think it does.
Properly produced feminized seeds make female plants that are just as likely to "hermie" as the parents.
If the parents "hermied" because too much fert was used, the babies will have the same tendency.
That does not make the plant a hermaphrodite.
Every female weed plant has the ability to produce male flowers.
To the OP:
You can keep it and try to pick off the balls. You probably will not get them all. so you will have some fem seeds.
If you grow those seeds the same way as you did the parent(s), they will probably produce male flowers.
This does not so much have to do with stability.
Maybe Barney's Farm genetics are just more persnickety than a lot of strains.
Try to figure out why the plant produced male flowers, then fix that. Or try a new seed bank producer.
Thanks for this information, I understand it better now. As to to much feeding, I dont believe that to be the case. PPMs have been really low. I always to light feedings, and havent seen any burns or anything on the leaves. Is there another way i can tell if im over feeding?
Not sure if this could stress the plant but... I have my grow box in my dark crawlspace. At first (during veg) i would take her out into my laundry room and do the watering/feeding there by a large sink for the run off. Id give the plant a little time tipped over to drain the excess water out. Then bring her back to the grow room in the crawlspace.
Other than that temps have been on the higher side 28-29C but theres tons of airflow (3 fans, 2 inside one outside).
I will be growing it out most likley unless balls pop up everywhere. But i still am not seeing any other signs of male flowers.
As to other seedbank producers, I stocked up on a ton of strains and different producers! Reserva Privada, Greenhouse, Kannabia, World of Seeds, Elite Seeds, Emerald Triangle, Next Generation, Female Seeds, Big Buddha, OG Raskal, and a couple more Barneys strains. Growing 2 plants at a time after this i think ill be good for a while, with 18 strains total
