When I last bought gallon jugs of AN 3-part it was almost $40 cheaper than the GH 3-part and when comparing apples to apples AN is a much better product than the GH. The others are too different to be a decent comparison other than they are a lot cheaper than both the AN or GH. I got a couple kilos of MegaCrop a few years ago and it seemed to veg the plants fine but did not flower to my satisfaction so I stopped using that.
Where the expense comes in is all the supplements that you mostly don't ever need but there are suckers born every minute and evey company makes them and charges an arm and a leg for too so bitching about AN is a little one-sided.
All I used from AN is the 3-part and Big Bud. Some of the Rhino Skin for silica with DWC but I don't use that in potted plants. 3 gal of nutes and a 500g tub of BB powder for $200 and I've grown a couple hundred plants with it and have almost half the nutes left. Nutes are maybe 10% of my total expenses to grow. Power at 30+¢/kwh is what really costs.
I don't give my money to a-hole companies like GH who never once said their products were used for pot and when my buddy mentioned pot to the tech rep on a call he got hung up on. Those a-holes had paid shills badmouthing AN all over the web for years and a lot of AN haters bought it hook, line and sinker. Now that GH is owned by the Scotts, Monsanto, Hawthorne, Roots and now Bayer line of corporate rip-offs that's even more reason to use AN if only for the pH Perfect technology advantage. I've done over 50 DWC grows since '01 and once I never had to test pH again AN is the only hydro nutes I'll ever buy but I'm going all organic now so won't be needing any bottled nutes. Never checked pH using them in ProMix HP and grows always went great. I always use RO or distilled water too as our tap water from the dugout is 400+ppm and 8+pH.
AN is originally a Canadian independent company now manufacturing in the states too using better salts than GH by far so I don't mind paying for that.
