The really good strains, Jack Herrer, Sensi star, etc, arent cheap.
Every really good strain ive grown has been a little pricey. In some instances your actually paying for quality, but many breedes and seed retailers have taken advantage of that circumstance and are charging big money for mediocre weed to infer its really good.
Another factor is name. Some famous breeders/companies have a couple 3 decent strains, and use their reputation to charge out the ass for the other dozen mediocre pollen chucking efforts they have up for sale.
Bottom line: Good strains arent cheap, but you cant use that as a guide because many mediocre strains arent cheap either..
the way I look at it.. if you get one female from a pack of seeds and get an oz from her... the pack has payed for itself.
Then if you are lucky enough to get more then one female and get clones then... shit.... thats bonus.
but I have never payed more then $125 for a pack....
what makes a 250.00 strain better than a 40.00 strain.
One is grown in hard mode, the other in easy mode. Hope that helps.
I think that question could best be answered by the zealots that pushed sweet tooth to the top of the food chain
actually I saw them going for $69/pack last drop for 15+ beans
