I just started a hydroponic grow as an experiment from one of my small potted plants, and its growing great! Much faster than the traditional method anyway, but I have a question about it. I am unemployed at the moment and dont have the money to by nutrients for the system. One of my friends said that adding epsom salt would be enough, but I am finding this hard to believe. Does anyone know of any house hold items I could use for nutes in this grow? I still have plenty of potting soil, so maybe a dash of that? It is almost done with the veg cycle now, if that helps.
