Causes of seeds

[SRS]

What would cause a female plant to have seeds if no male plant is present?

[StoneyTony]

Poor genetics and stress to the plant are two of the biggest.

There is a good tutorial at www.growweedeasy.com/7-flowering-stage-problems

Yeah, check out the tutorial. You might have a hermie, caused by stressing the female in some way. Have you had any contact with male plants? pollen can be transferred by clothing really easy from one location to another. Have you actually seen or felt seeds in the calyx or just seeing bumps that look like they might be seeds. The first time I grew a plant that developed huge calyx I thought they might have been seeds developing but no worry, wasn't the case. If there are pistils growing out of the "bumps" then they are just well developed calyx. If there are no pistils and you can see little "nanas" sticking out then you have a hermie. Or any other signs of male parts. If your plants are still growing then hope all turns out well. The tutorial will provide you with all you need to recognize them and what to do about it. Cheers.

It's a hermie by breeding orit can turn hermie by stress or light leaks dureing flower

I just harvested a big girl I ended up getting half a dozen seeds off. Never near a male and never saw a nanner, it must have been a stealthy one

Nature it's crafty.

I put 2 t5 uva lights in with my 1000hps and had them on 12 hours they burnt the crap out of my plants and stressed them enough to grow seeds. (thought it was a good idea lol).

Any environmental stress (ie heat) which is not corrected in a timely manner, can cause a plant to get into survival mode and hermie.

I'm suspect of the "bad genetics" theory, as I have taken seeds from plants deemed as bad genetics- and grew in a more controlled environment with success!

Also, you can get a seed or two out of nowhere.
The good news is you have fem seeds to palnt.
