THC AUTOFLOWER HELP

So I'm new to all of this and I know this is probably a crazy question to most of y'all but??? I'm looking for a good genetic seed that is low in THC under 18% but would like it to be around 15% my wife want to start smoking and one hit puts her past where she wants to be. So if I can find something that even if she had to take a few hits to get her high. Please help me out!
Thanks

Lots of options out there. Look for a 1:1 thc/cbd strain and that’ll keep the thc lower.

I wouldn’t worry too much about potency. Just smoke less and go slow.

Anything you grow will have a lot of variation in it. I want hi thc but some plants from same bag of seeds do nothing for me while their sister gets me ripped.

Only way to know for sure is to grow it out.

I save the ones that do nothing for my wife. She has the same problem.
