Hello Greg
I have a half dozen strawberries that is just now producing fruit. I have them in
grow rocks in one gallon system but I don't think they need that much root room. I am going to try to grow them in 2 liter bottles with the 16 oz Solo cups.
I haven't tried any medium but grow rocks so I can't give you much help on the success of other mediums until I try them my self.
I will be building all kinds of hydro gardens this spring to put on film. I will post pictures as I complete them.
Ron
