An acronym comes to mind.
KISS = keep it simple stupid
No im not calling you stupid, or offering a kiss...
The basic line up is all you need. Doesnt matter what you pick for company really. I personally think AN is a master marketting scheme. Yea they have some good stuff, that you could probably buy 1 bottle of elsewhere to replace 3 of theirs.
I like to pick and choose what i use from different lines. Right now im using up some leftover greenhouse nutes from Humboldt County's Own. Their micro, bloom, and magnesium for soil, then g-10 and snow storm for additives. Only thing from AN i use is their overdrive.
