"What's the deal with Attitude seeds selling exact strains from other internet seed banks like Nirvana."
Seed Banks like attitude and Nirvana sell seeds for breeders like Serious and Dutch Passion. I believe Nirvana does their own strains and copies the name of a famous strain. For example AK48 by Nirvana is an indica stone and AK47 by Serious is a rocketing high. A lot of classic strains like White Widow are bred by many breeders.
"And why would someone want to order from Attitude instead of directly from Nirvana?"
Because Attitude is one of the best, most trusted, seed banks in the world and Nirvana are deceitful scum. Really, a lot of people swear by Nirvana - they have some excellent strains that they should have made unique names for and perhaps they'd be classics by now.
"I have nothing against Attitude but sometimes Attitude's description of a particular strain is a different from the additional information that I think comes from the original seed bank."
Post a link to the same strain in with each company and we'll pick the differences apart.

"Does anyone else notice the contradictions in THC and things like that?"
Gas chromatography-mass spectrometry is a method that combines the features of
gas-liquid chromatography and
mass spectrometry to identify different substances within a test sample.
Using Gas chromatography your
marijuana is separated into each molecular component. Then by using Mass Spectrometry each component is individually weighed. The result is a ng/ml (nano-grams/milli-liters) measurement of every molecule present in your
marijuana sample.
What I haven't been able to find is what is being used as the equation to determine percentage - is it: (the weight of the THC) / (the weight of the total
marijuana sample: dried or wet?) ... or is it: (THC) / (weight of resin in sample) ... or is it, without using a GC-MS: (resin) / (total weight of sample ~ dry to get highest percentage)?
IMO THC percentages are the biggest load of bullshit a seed bank can shovel. Disingenuous at best. Look for a smoke report.

ps my money is on equation three.
