So u think they payed those cats in cannabis cup to claim they used there products for better growth?
I know little about the CC, but sponsorships wouldn't surprise me. Everything is commercialized, especially when the CC is named after a commercial entity (High Times). That would make representation of fertilizer products non-random.
I don't think anyone has said AN won't grow. Just that it's rather opaque and expensive with it's three-dimensional product "lineup." (More of a vibe/theme than informative).
For example, I grew this using a dry product that costs about $1 per plant (per grow). I did it under inexpensive LED lightbulbs from Home Depot running only 20-22w/sq ft (ideal would have been 32-35w/sq ft):
Right now the buds are in the final stage of drying in a 10x14" plastic container. They're 4" deep.
I'm sure AN does well too. I don't understand why some people are obsessed with what others do. I figure people don't spend more for no reason. If there's no reason, they'll figure it out themselves. It's not like they're in a sinking boat, their lives at risk, helpless and needing rescue. If AN is unnecessary, they'll figure it out. (I'd encourage you to report posts if you feel you're inhibited from discussing your choice of nutrients.).
Good luck.
