In my years if the support of the growing, use and legalization of cannabis I have come to realize that most of the information available on the subject is strictly opinion; most people just want to bash on each other because, of course, nobody's opinion is as great as theirs (a great flaw in humanity.)
Most of the information floating around about cultivation is the opinion of that particular grower; nutrient companies will say/do just about anythin to get you to buy their product.. and they should, those are basic priciples of business. So when a nutrient company offers scientific evidence/proof of the performance of their product sit should be taken into consideration, at the least.
The point is Advanced nutrients is the ONLY company who will even openly admit that their nutrients are forulated specifically for cannabis, they make almost anything you could need to grow marijuana, from nutrients and lights down to trimming scissors and bud trimmers up to $15,000... Even if you are a hater and sing the praises of other nutrient companies- go to the advanced website and read as much as you can (there's plenty) of the information/research they put into making their products. They have even done a side-byside study growing 1 strain of cannabis in several rooms where every variable was controlled and the only difference in the grow rooms was the nutrients used. The results were amazing, not only did AN outperform all of the other nutrient companies but the room in which Dutch Masters nutrients were used had the poorest quality of plants and even seemed to deform the plants until they looked like a totally different strain. This is not all, AN also has an offer up, any nutrient company willing to do a side-by-side grow and prove that their product is better and NOBODY is willing to participate! Think about that.
Before anybody even tries-I do NOT work for advanced nutrients, I don't even live in the same country, I wish that I did though because nutrients are getting waay to expensive (thanks to trends and ignorant t.v. shows such as "weeds")... I just think that people who want to talk crap about AN have no understanding of the scientific process. I am currently using Jungle Juice because I have no need whatsoever for my nutrients to control my pH for me and I have great results EVERY time! So, if you have used AN and had negative results then, I assure you, YOU were doing something wrong, not the biggest hydroponic nutrient company in the world who spends millions of dollars formulating prize winning nutrients (not to mention their nutes have won several cannabis cups.) If you think that they are not good nutrients then that will show your lack of experience/importance in cultivation, the truth is a good grower can produce good results regardless and if your tiny closet grow yeilded 2 grams instead of a whopping 3 then that's your fault, not AN's. Argue all you want to, I use AN's cheaper formula and have results that I could not be happier with & if you know of a better nutrient company then perhaps you could e-mail them and convince them to take AN up on that side-by-side grow and prove them wrong because so far NOBODY has the balls to do it including: Dutch Masters, General Hydro, Fox Farm, Humboldt or anybody!
Educate yourself with science, not groundless opinions.
