thats pretty cool you hsould just buy some seeds online and plant them there as they grow without any attention.
Tight plants! That would be cool if you grew them out and made like bread with the hemp seeds. Or made a bracelet or something with the hemp fiber. I have no idea how to do that, but you should look it up. Haha you could show people and be like yeah i made this out of the hemp plant growing in my backyard!
Looks like hemp to me, but I'm no expert. You should take more pics of what you believe are buds and/or female plants so people can figure it out for sure. I also agree with Matt 2 posts earlier
you're gonna want to kill the males... but you'll want to do that in the middle of the night wearing lots of dark clothing and definately not coming directly from or going directly to your house.
I haven't read all of the replies, so I don't know if anyone has said this yet, spare me... If it's weed, the little 'balls' on the plants indicate males - females don't have those. Get rid of males IMMEDIATELY. Not only will it fuck up any female plants that might be growing there, but having one male in an area could fuck up EVERYONE else's crops in the area. We had a hemp field (hemp is made from male cannabis plants) here one year, and it was only one year/one crop because the guy that owned the field was getting serious threats saying that if he ever did it again, his entire family would be killed... that's how many crops it fucked up. You won't get anything but angry growers (and a headache, if you smoke it) out of male plants.
ive found hell of a lot weed its evry where in my town but i cant see any buds is it smokeable and stuff
