Hydroponic / aquaponic setup using food safe pipe and materials.
I'm retired and started a small hydroponic set up for personal use and want to expand into aquaponics. I've done endless research on line for pipe and materials that are " food grade safe" ... many folks use PVC which I question .... I'm looking for 6" ,4" and 2" pipe HDPE, LDPE food grade pipe. smaller pipe and fittings I'm able to find using polyethylene. What is your take on this .... I know some of the universities have setups as well as large commercial operations. Any help or input would be appreciated. Phone conversation would be nice if possible. thanks, Gunther Miller
