What methods do the big name breeders use to feminize their seed lines?

[Mr. Diamond]

Stress, Gibberellic Acid, Colloidal silver ... which method do each of the large breeders use to create their feminized seed line. I know DNA uses Gibberellic Acid ... at last I think I saw a youtube video where they said they did.


Thanks guys.

Mr. Diamond
I love seeds.

i thought it was about a hermi bread back in to a strain 4 times giving f1 f2 f3 f4. f4 being your least chance of the hermi trait. but i could be waaaaay wrong

i believe silver thiosulphate is the new rage... silver colloid is commonly used too, as far as i know...

I just had a run of 6 clones of Apollo 13-BX that started producing seeds after a light stress incident.

I didn't realize it until I began trimming for water curing.

Needless to say I ended up with 800+ feminized seeds from stressing the plants with light. And I still ended up with an ounce of usable flowers.

Best mistake I've ever made. I'll never have to buy another seed ever...LoL

Have you sprouted a bunch of them to confirm they are female?

 

[OGEvilgenius]

They'll be female or unviable. Unless he had a male lurking around.

I thought they would be female or unviable OR HERMIES. Unless he had a male lurking around.

No.
Feminized seeds are only as likely to "herm" as the plants they were made from. Most varieties are unlikely to produce hermaphrodites that have an X and a Y chromosome.

thank you I thought they were more prone to hermie, ... I have a bunch of seeds that I thought would most likely hermi on me so I started only one of them now and it's got nice buds 6 weeks into flowering

 

[Budgoro88]

I only had one strain of feminized seeds hermi on me and thats from light leak my own fault
