Collection: Grow Micro & Bloom - 3-Part Base Feeds

Three-part base feeds split into Grow, Micro and Bloom bottles, mixed in different ratios as the plant moves from vegetative growth through to late flower — more precise than a two-part system, at the cost of an extra bottle to manage. Shop Advanced Nutrients' pH Perfect Grow/Micro/Bloom, GHE Terra Aquatica TriPart, Future Harvest's 3-part range, and Advanced Hydroponics' Dutch 1/2/3 system. Always add Micro to water first, before Grow or Bloom — mixing bottles undiluted causes nutrient lockout.
