My supplier said they were unhappy with something. He is also going out of stock now, and going with the General Hydroponics lines. He said that AN is slow at getting orders out and is no longer dependable. He also believe that General Hydroponics products are as good. Not sure myself. But did try some of his suggestions in this grow for the vegging. Along with Piranah. I simply could not turn down the chance to try the Connoisseur A and B (AN). Have used the Sensi line before. I do like their products. It will be interesting to see how the Connoisseur A and B (AN) works.
