Does anyone know the proceedure for cleaning the grobo between grows? Please help.
All I ever did was wipe it down with diluted bleach water. Just clean it real good. I haven’t had any issues.
Run a 50/50 vinegar to water in res, then rinse with clean water.
There is a recipe for cleaning. It will let you drain and fill with vinegar / water as much as you want without adding nutes or balancing PH.
Hope that works better than the grow cycle
