As you sort through the assorted advice, gotta remember that each individual poster has their own reasons or agendas for choosing this over that.... some grow for a hobby or personal smoke, some flip part or most of their grow into cash: either on a small scale or large scale,,,
the relevance here is for someone on a larger scale; cost per plant/grow matters...for others; hell given the street cost of weed, they could give a damn if the results wash out the few extra bucks for nutes & additives...
make your own choice, but realize the sample sizes of the assorted opinions here...people say "I've done "X" number of grows" and that's relevant, but with so many other variables, my take on anything less than a large scale , government funded, university researched study is with a grain of salt....
I dunno, maybe a quick pro/con decision table might help us growers with lighting, nute and growing method choices
For instance:
- soil? if your a hobbyist and flavor & health are priorities, maybe check out the organics section
- hydro? if you just want simplicity and want to save $ at the same time: just use maxi-grow (or as recommended here: dynagrow) ...I can tell you from personal experience, just using Maxibloom works
- the GH 3 part is tried and true, other say Lucas using just the Bloom & Micro .... I've done both; I saw no big difference....but again: sample size
- some of the younger/trendier type swear by using 4,5,6 even 7 different chems, additives & nutes...who knows? personally some of it makes my head spin....
...whatever you choose, just remember on the one hand; weed is just a plant, people make it into this super sensitive pussified thing, but really most of the issues is because half of us weren't gardeners 1st but got most if not all the growing info from pot forums (where everyone, incl. me, can sound like a expert)...
But on the other hand; unlike tomatoes, weed is smoked, and interacts with your lungs....and lung tissue is pretty damn sensitive to carcinogens, poisons, et et.... your plant is what you give it...just something else to consider
