How do I kill pathogens in the reservoir, BEFORE they hurt my plants? You can use products like SM-90, Hygrozyme, Florashield, or Humboldt’s Mayan Microzyme. You can use any enzyme based product that your current nutrient is compatible with. I have a lot of mosquitoes how would I get rid of them WITHOUT using pesticides? There are deer/gophers/birds/raccoons/ect. eating my garden, how do I stop them from eating my crops?
