same strain but different prices.. why ?

i wonder why do same strains have different prices in different seedbanks !

forexample;

in X shop: Jack Herer (Sensi Seeds) costs € 150 (10 regular seeds)
in Y shop: Jack Herer (Green House) costs € 25,95 (5 feminised seeds)
in X shop: white widow (power seeds) costs € 26,95 (5 regular seeds)
in y shop: white widow (Green House) costs € 35 (5 feminised seeds)
in X shop: Durban Poison € 19
in y shop: Durban Poison (Dutch Passion) € 41,95
....

Why Nirvanashop has very low prices?
which websites have original and reliable seeds?
how do i know which are the original versions?

Nirvana seems to have low prices because they don't list any seed companies, just says "Jack Herer", not Sensi Seeds "Jack Herer". So it's kind of a generic version.

Attitude has the best variety in my opinion and information on not only the strain but also the strain producer.

I know for sure that Green House Seeds were the original breeder of White Widow but not sure about the other ones.

Well to me nirvana looks like a bunch of knockoff strains thats why they are so cheap.
Sensi seeds has the real jack herer and everybody else is just breeding thier own version of it Not the real jack herer.
Shantibaba left greenhouse and went to mr.nice he had the original white widow which is now black widow.

the above poster is kinda right.. when you pay the 149 or whatever and get the sensi seeds jack herer, your getting the original cup winning strain.. when you buy the nirvana version for whatever price, your just getting some strain that they happened to call jack herer, despite it not having the same parents as the sensi version...
same with say white widow.. tons of breeders all have theri version of a white widow.. but the original version made by shanti was put out by ghsc, now called black widow put out by mr nice seeds.. so although you can buy a white widow by almost any seed company nowadays, i highly doubt any of them have the same exact lineage of the mr nice version.. it is all kinda bs that every company is allowed to put out a strain with the same name even though they all have very different lineage.. same with sour diesel.. a lot of breeders have their own version of sour d, and each is very differnt from the origanal clone only strain that came from the chem family..
so what does this all mean to us growers and buyers of seeds? i would say its buyer beware honestly, and do your homework and try and find out who has the real deal genetics and who just has a strain that they are calling another popular name, if your looking for the real deal strain that is.. many people are just happy having the cheap imitation and don't really care about the lineage of their plant... its all really up to you and what your willing to accept in your grow room..

i dont really price shop because attitude has been very good to me and they have a range of price points. i always get extra freebies and its on my porch like 6-7 days from when i order. i like nirvana too but thats the thing, when i go to order from them i feel like im getting the generic brand. and i'd rather just get the real deal.

that black widow is a must have. i was just talking about it in another strain hehe.

I agree with him.

Nirvana breeds there own seeds. That is why they dont list a brand. They are the brand. And many of the strains are knock offs and stolen genetics.
