Dr. Russell Sharp breaks down the three main types of surfactants (anionic, cationic, non‑ionic), how they’re used to re-wet hydrophobic grow media, and their roles as adjuvants and insecticidal soaps. He warns against sodium-based products like sodium lauryl sulfate and recommends sodium-free alternatives, highlighting Eutrema’s clay drainer, yucca extract, and non-sodium insecticidal soap.
