Just wanted to let you know, you need to be very careful as to the type of metals you put into your reservior. No Copper, Brass and deffinently no Bronze, as these metals will react with the nutes and more than likely kill your crop. Stainless steel is about the only thing I would recommend going into your reservior.Yeah, until my new radiator, cooler wasn't really possible
30 year old Westinghouse boiler radiator, original fan. Built like tank, from an era where quality mattered and steel was apparently free. Radiator + 1/3 hp pump + 40 degree weather makes 9k worth of lights seem irrelevant.
THe ph at which hydrponics need, can and will leach excessive copper into the system and will have detrimental effects on your crop at a minimum, at worst they will die. The copper that is in the nutes, is nothing compared to what will leach out of the lines over time. Hope that helps M8Are you sure no copper? Seems weird, esp. since copper is already added to nutes and used for water lines.
Guess I'll find out, since even though I *think* the radiator is stainless, I know the fittings to it are copper (only a couple feet, resoldered it and hooked it to threaded 3/4" PVC b/c is 20x cheaper)
