Lol, I don't know... 30 feet? That's a bit too high for a pot plant... The biggest one I've ever seen was in a back yard and it had to be like 9feet tall!
sorry...not a dumbass...this is just what a vet from vietnam told me. maybe he was full of shit. notice how I said "I heard.." not "Hey guys my ganja plants are 30ft tall!" I've never seen one. good luck on your hunt
personally, I tend to not believe anything until I see it. I think it's definitely a possibility that ganja could grow that tall. the vets called it cambodian gold.
some google searches turned up evidence of 14ft plants... largest one I've personally seen was 2ft tall.....
i've heard a few people talk about these monsters, mate. I don't believe nor disbelieve it. does it make you feel better trying to make me out to be a dumbass when I'm just relaying information I've heard? anyway, your best bet is to talk to some people that've been to cambodia 'cause if you want to find the worlds tallest marijuana plants that might be a good place to look. have fun
although Cambodia does have a great climate fro growing marijuana and a long growing season, the fact is that if a plant grew to 30 feet in Cambodia it would have to grow an inch a day from the beginning of germination. it doesn't seem likely. also any bud from that plant would be pretty weak and not called Cambodian gold. it would be called ditch weed. but if the plant did have good weed than then plant would have to grow over 2 inches a day from germination during the vegetative phase and bud like hell during the flowering stage. even less likely. you got told a story, a fictional story.
I've heard stories of African outdoor strains growing between 10-12 feet. I'm not sure that they are smokable though...I hear they are more like annuals.
