So can anyone with breeding experience tell me expactly what to expect if I bred male and female northernlights together straight from Nirvana?
Would I get inconsistant results? Would the offspring be pure northernlights or some midget/dwarf northernlights?
Should I even hassle with breeding pure? Or should I skip that altogether?
You ask a very good question about NL and the crosses of Jackberry, I starting trying to answer yesterday when I lost my connection. Ok first up is the NL from Nirvina Seeds. This can't truly be answered without knowing a few things about the strain. I have looked at their site and they do not tell you if the NL is a f1, 2 or 6 so the breeding question as to breeding pure is not answerable. If you are breeding a f1 then you are going to have many pheno resulting in the next generation. If it is a f2 and you breed them they will start showing more of the parents they came from. Then with each generation provided you are selecting the same pheno each time to breed you will see a more true strain start to emerge.
You ask if this is a waste of time? Not really but this just depends on what you want out of a grow, no one can answer this question but you and what you desire to achieve growing and breeding. Do you want a true breed? If yes talk to the breeder at Nirvina and ask what f type the plant is. If you just want to see want you can do and start from scratch breeding then you will spend several generations of growing to achieve this, but the rewards and knowledge gained is immeasureable.
Next question about breeding Jackberry to a Haze. You are taking a basically indica plant and crossing with a sativa, good hybrid but many many combos will emerge. So you need to ask yourself this, Do I want a haze pheno with jackberry or a jackberry with haze qualities. This basically is going to tell you which male to use to pollinate your female. My thought would be to use a Jackberry male to cross with the haze to produce the haze pheno and vice versa for jackberry. Then the fun starts picking suitable phenos in the next generation to backcross to. You also have to ask yourself what plant structure you are looking for or like in my case I am only looking for the flower and not worried about plant structure (breeding for a specific trait).
I would suggest to go with the purest strain you can find for the haze, something in the IBL area or at least a good f5 or better. You might consider crossing this back to a Sannie's Jack since it has some of her in the Jackberry. This might not be the exact cross you are looking for but the lineage lines up good to reduce the numbers in selecting.
Most seed companies are not interested in you making breeding stock out of their seeds and I think make it hard to accomplish this today. It has become a big money business with many strains, many breeders and not so many breeders which are concerned about passing on breeding genetics. Sannie and his crew actually encourage the breeding and their stocks have many f2s,3s,4s and such which lend themselves better for breeding your own seeds with the results you want. Also, I should point out that I have asked and received many helpful hints, how tos, which phenos breed best and such from the crew at Sannie's. They go out of their way to answer your questions and point you in the right direction.
I hope the ramble wasn't too boring or scared you off of trying the breeding. This sure gives me a reason to get up every morning and tend to my plant and has given me a goal to live for to see each cross come to the end I am looking for. Best advice, breed, breed and breed somemore. Take lots of notes of your crosses with pictures to keep in a file so you can see the results, phenos and what you did. The end result is less money to seed backs, more enjoyment to you and maybe some phenos that only you are lucky enough to have.

Here is your reading assignment, lol just like going back to school.
Happy Growing and good luck
