What's the difference between base nutrients and supplements?
Base nutrients (like GH Flora Trio or Athena Core/Bloom) provide the primary NPK and micronutrients needed for plant growth. Supplements like House & Garden Roots Excelurator, GH Kool Bloom, and Aptus Fasilitor are added to the base feed to enhance specific aspects like root development, flower density, or stress resistance.

What pH should hydroponic nutrient solution be?
For most hydroponic systems, maintain pH 5.5–6.2, with 5.8–6.0 being ideal. For soil grows, target 6.2–6.8 pH. Always measure and adjust pH after adding nutrients, not before. We carry pH meters, up solutions, and down solutions from Bluelab, Apera, General Hydroponics, and more.
