Plant real weed bag seed outdoor guerrilla style. It is the real thing but not wasting money on beans if its a fail. If you do good you get buds vs tomatoes. Even if the buds aren't huge you could still make hash with all the trim.
Reason I say this hops and tomatoes are related yes. However have totally different needs when it comes to optimum growth. Practice growing the real thing. I would also advise getting a good growbbook. That way you would feel comfortable before jumping in and not panic if something happens.
Shit I studied 2 different grow books and high times, skunk, cannabis culture magazines. I only got the grow specials or interesting ones by the way. I did this for about 6 months before jumping in.
This was all before riu forum was up. I got Mel Clarke's book and Ed Rosenthals book also. And marijuana success tips magazine looking book.
