Few yrs back when I was able to do outside I ran only one plant after culling the rest, it was a brute .The stem was a trunk and was as big around as a beer can (truth)
that brings back an amazing memory for me.
Years ago, living in Albuquerque, NM.
I was young buck renting a guest house on a large hacienda down by the Rio Grande River.
I used to park my second vehicle at the edge of a pasture. One day I was cleaning the interior and tossed the contents of the truck ashtray - contained a few small roaches & seeds.
Fast forward couple months-
I parked my truck and noticed a large pot plant sticking up above the weed line. Holy crap – one of the seeds I tossed months earlier took hold. I investigated and noticed how healthy the plant was and that the ground around it was moist. I recall the landlord telling me not to park on that spot because there is a septic tank with a leak problem there. Holy crap – that plant tapped into 24/7 water/fertilizer source.
By the end of Sept I felt like an expectant father. Problem was that the weeds/grasses surrounding and concealing part of the eight foot Monster were turning brown, while the plant was neon green. I swear – I think the pilots in jetliners could have spotted it while on their approach to ABQ airport!!!.
I was traveling for work then. So I made a deal with young guy next door. That he keep an eye on it, park his vehicle back there for the next couple weeks to prevent anyone else from using spot and we'll split the take 50-50..
At mid October the trichs were getting rosy. We then made a midnight mission to harvest. I had to use a handsaw to cut the trunk. Don’t know how many lbs we got – but I know I did not buy herb for two years!!
and it was KILLER weed..
All that from a randomly tossed seed!!
