They are a definite must in any indoor garden running on an automated feeding system. Back To Top • Q. Do certain plastics leach back into the nutrient solution like Rubbermaid containers and plastic pails for example? Are these types of products safe for use in a hydroponics system? A. Usually products such as Rubbermaid are rate as food grade based on the fact that food could quite possibly be stored in them. Always look for food grade plastics when seeking out material for a hydroponics garden. Better to be safe than sorry. Some plastics ca
