Hi, Iīm beggining to use PMDD. But here, in Brazil, itīs not allowed buying KNO3 for security reasons. So, I need to understand: 1) Whatīs the purpose of KNO3 in the PMDD solution? To give K? To give NO3? Both? 2) What are the sources for that(those) element(s)? Thank you Gustavo Adolfo Lapido Loureiro (21) 2507 - 5464 --- StripMime Report -- processed MIME parts --- multipart/alternative text/html ---
