Query: Good stuff

What can really be said about nutrients like this. Either they are there or they are not. I've only used these and Humboldt. I prefer Humboldt because of the shape of the bottles, but they are a bit more expensive. The Humboldt bottles line up more neatly on the shelves and have better information on the bottle, but I can't tell the difference between the performance of the two. These nutes are color coded and the Humboldt are not. I add Ginormous also. Good luck :)
