Tell me more about Bio Stimulants i want that info!!! Lay it on me, what did you use, what was the setting and how do you know it worked? I know theres solutions to fighting non beneficial fungus and mold by creating soil and plant health. That has been my primary focus since i grew with salts in coco outdoor and got PM and Bud mold really bad. My conclusion was that salts, and not living soil, grows plants with weakened immune systems, making them much more susceptible to infection. I have not had a single instance of it in the last season, and there was bindweed growing within 20 ft. that was totally infested with PM, and i personally attribute it to my conversion to "organics"...But i think its a full picture thing were talking about here, not just bio stimulants, but dirt, food, overall conditions, and the use of living soils, and foods that feed the living soil web.
