Advanced Nutrients Grow, Bloom, Micro by AccessHydroponic.com

http://www.accesshydroponic.com/viewCategories.asp?idCategory=20 Advanced Nutrients scientists conducted extensive research on plant tissue samples and found plants perform best when the ratio of application of our GMB(Grow-Mirco-Bloom) is 1:1:1. Professional and Grand Master growers may have the experience to experiment with that ratio, but our test gardens have shown great results with 1:1:1. When our GMB is used with the Bigger Yields System, nutrient absorption is higher than ever before possible with any 3-part formula.
Advanced Nutrients GMB is manufactured with the latest coatings, chelates and processes, which means much more nutrition is absorbed by plants. That's why you use a lot less of our nutrients when compared to General Hydroponics, which is 25% weaker than our 3-part.
