changes in ph,ppm,or toxic build
 
Ron: What media are you using with Miracle-Gro? Do you notice any changes in ph,ppm,or toxic build up other than what you had with hydro solutions. Plants look great I hope you have continued luck with the set up. It sure beats hydro firts prices. Nurse Duckett

I am using grow rocks as a medium.
The PPM is a little low around 550 but I am not going to go by PPM. I am going for awhile with how healthy the plants look and what the tomatoes taste like.
No signs of toxic build up yet but I don't think I have been growing long enough with Miracle-Gro to see any.
