I Love Neptune's Harvest and Atomic Bloomz ! Best Garden I have ever had in my life !

I Love Neptune's Harvest and Atomic Bloomz ! Best Garden I have ever had in my life !
I used Visible Results in 24-48 Hrs! Atomic Bloomz Hormones w/ Vital Nutrients Works with Advanced Nutrients , Fox Farm , Botanicare , Dutch Master , General Hydroponics , Miracle Gro and All Other Base Nutrients ! as a foliar spray and amended the soil with Neptune's harvest and the incredible happened to my roses. In 3-4 weeks these rose bushes were double the height and size of the roses I planted last spring. On top of double the flowers. I now used Visible Results in 24-48 Hrs! Atomic Bloomz Hormones w/ Vital Nutrients Works with Advanced Nutrients , Fox Farm , Botanicare , Dutch Master , General Hydroponics , Miracle Gro and All Other Base Nutrients ! on the older roses that were lagging behind along with Neptune's harvest as a top dressing around the base of them. In 2 weeks the old rose bushes were as big and had twice as many flower buds and about the same amount of flowers as the new ones. My wife and I are also using this combination on our vegetable garden . Never have we had tomatos as sweet and as big as this fertilizer combination produced . They are both excellent products and we both recommend to friends . I am so glad we started shopping on Amazon ! With out Amazon we would have never found these 2 products .....Visible Results in 24-48 Hrs! Atomic Bloomz Hormones w/ Vital Nutrients Works with Advanced Nutrients , Fox Farm , Botanicare , Dutch Master , General Hydroponics , Miracle Gro and All Other Base Nutrients !
