If the plants have new root growth(very important !) you see immediate results ..within 2-3 weeks. It is normal for some of the old roots to die ..they flush out when you water. The yellow & red phal in the far right of the picture has thrown a second spike...I was quite amazed that the buds/blooms didn't die when I switched them to SH...that convinced me that phals love hydroton !
Good to see you too BD !!![]()
