You will most likely get a male due to the seeds being regular, but I would not be suprised if your turn out was all females. I have had two 6 packs of reg beans come that turned out all female. 1 pack was DNA and the other was Cali Con. Depending on the genetics and the breeder you can get a 3:3 ratio or a 5:1 ratio and even sometimes a 6:0 ratio. Whenever I get all females from a regular pack it makes me thing that the company was out of stock in regular seeds and shipped fem seeds. Or they just lied and sent you a different breeders seeds, but i doubt this is true.
You are most likely going to get a male in the batch. The reason people might have said it will be all females is because that is what happened to them, or they were mistake and mixed up feminized and regular seeds.
