I completely agree with you. That is why I am pretty strong on mixing amendments into the soil and then adding bottled nutes. Iguana juice is primarily what you brew up (fish emulsion and some others but I can't think. Right now ha ha) sometime it does seem like the quality, not only in taste but also in potency, is better with my 100% live organic soil (no bottles) but as you said it is not worth the trade off. I usually average about 5-8 now with the strains i run but with that mixed soil it is n the lower side of that number...sometimes even less.
Im with you man. Kinda in the process of pursuing something like that. But I won't ever consider myself pro until I write a book and have more then 100 people buy it
