MG and FF both have good products....
some products from MG is not made for people who are ANXIOUSLY waiting for results or the ones who have babysitting issues with their plants, and end up killin their plants with too much LOVE and by smothering them to death...
if you want to do a quality test... get some expert growers to do it... because if you're not an expert, most likely, what you think you're doing right with MG, is probably wrong... look how many people on here have successfully grown with MG... how can you debate with those, that have done it.... this argument will go in circles forever, just for the simple fact, people who fuck up with MG will blame MG before they blame themselves.... stick with what you know and roll with it, don't try to change minds and influence others, because what works for one person, doesn't always work for the next
