It's always mildly amusing to see how the haters throw out wildly inconsistent or blatantly made-up facts to support their hate.
"900+% margins"
Seriously? No one outside AN would have access to those numbers so unless you're claiming to be an employee you're clearly making that up.
Even the most basic understanding of economics makes it obvious why that's so ridiculous. Even if you can sell something at a 900% margin Econ 101 will clearly demonstrate there's actually more total money to be made at a lower margin. As price decreases the number of people willing to pay the price increases and your total sales at the lower margin actually generate higher profits.
Claiming a 900% margin is STUPID. If that were true they could run every other nutrient company out of business in less than a year simply by operating slightly over cost and underpricing the competition. And then, if they were as evil and greedy as the haters say, they could jack the price to whatever they wanted because without any competition we'd have no choice.
And the people in the shops are employees of the shops, not Advanced Nutrients. Duh. That's like getting mad at the car manufacturer because the salesman on the lot pulled a quick one on you. He works for a dealership, not Ford or whatever.
Finally, don't be naive about labels. A label-lawyer will look at the label on a nutrient and think he knows what's in the bottle. Not true. The label tells you what is in the bottle that they're REQUIRED BY LAW to list, and not what they're required by law NOT TO LIST. Those are both important things to keep in mind. There's three categories of ingredients. Stuff you HAVE to put on the label, stuff you can put on the label if you want to, and stuff you cannot put on the label.
The label on a bottle of Hammerhead is far from a recipe to duplicate it. You can certainly go out and buy monopotassium phosphate and potassium nitrate, and mix it to get a solution that has the same NPK as Hammerhead, but if you think you have the exact same thing that comes in the Hammerhead bottle you're dead wrong. You need to also know what goes in those bottles that the bureaucrats don't let them tell you about.
