ow nuts........
man I know where your coming from, this past summer I had a volunteer come up in the yard. I transplanted it fed it fish shit. and gave it lots of sun it grew like a weed (pun intended) and it was just soooo pretty, but lo and behold it showed some huge nuts just like yours.....
keep it up though. that journey led me to this site and I purchased some seeds from the doc and two weeks later i got some kiiler plants coming up and this time i'm gonna have at least one gal....
just plant at least 3 seeds and you'll get at least one.....
