so today i was riding my quad and i stopped to take a pee. i walked over to a fence and when i looked down i noticed a marijuana plant by my foot. when i looked around i noticed there was a little plant every 10 ft or so. they were only about 5 inches tall with no buds on them. no body is ever around those parts of the woods. could they be wild? will they grow themselves? how long until they grow bud?
