Here we go again, look at all the haters hating as usual...When growing in a soiless medium or in hydro you have to provide things like amino acids, hormones, chelates, plant growth regulators, vitamins, enzymes, yeast, yeast extracts, organics, carbohydrates, microbes, beneficial bacteria, and beneficial fungi if you want your plants to live up to there fullest potential.
And sorry folks no you can't get all of this in one bottle, and no you don't have to get it from Advanced Nutrients either...So just like if you was creating a living soil you would have to buy 8 or so different products to add to that soil the same goes for soiless and hydro if you want all of the benefits of the things I mentioned. Advanced Nutrients which I prefer as well as other companies provides all of these things it's up to the grower discernment.
