Just because someone's been doing it longer doesn't mean they do it better.
Who's been making cars longer, Ford or Honda? Who makes better cars?
Doesn't matter. Because how long you've been doing something only matters if it's something you can brag about in a commercial. How well you do something is all that's important unless your business hinges upon long-term stability.
If it's important to your growing today whether the company you bought the nutes from is likely to be around in 30 years then yes, how long they've been in the business is important.
People like to say Advanced Nutrients spends loads of money on advertising but that's not based on anything I've seen. They hardly advertise at all. Weeds - that's what you'll point to first. You'll guess (key word here is "guess") that AN spends a lot of money to get their product on Weeds but you'll just ignore all the articles we've read saying that Big Mike is a consultant on the show.
Consultants don't work for free. Probably doesn't cost them a cent to get their stuff on the show.
Maybe you'll say that the flashy labels cost a lot. Doesn't cost any more to print than any other color label, and it's a one-time cost to design.
I've heard all the crap and that's all it is. To date I've never seen anyone actually back up the claim that AN spends all this money on advertising with something real. It makes sense to me that the money is actually going where they say it is. Research, all the charity work they do, stuff like that.
But hey, everyone that buys AN is gullible anyway so why listen to what I think?
