There are most certainly all male seeds. if the mother is stressed during seed production she will throw all male seeds. i just read a thing on it a few days ago. some scientist have been experimenting with it for like 3 years now.
i doubt that you have all males johnny was just pointing out that the possibilty exists just like you can get all female seeds. Work would have to be done to acheive it and there isn't anybody busting their ass to provide all male seeds.
yeah i should have tried to sound a little more positive sorry about that. keep your ph right if it gets low and your soil or water is acidic you can get males too. sacs can be differant some in a few days some in a week. just get rid of em if your sure they are male.
statistically 60% of all seeds that are "regular sex" are female. Males usually show sex first...and usually are faster growers to boot. They can be weeks ahead of females.
