      Run to Waste Nutrients That Feed Fresh Every Cycle

      Inert bases matched to run to waste media

      These formulas are built for single-pass feeding in rockwool slabs, perlite bags and dripper systems. Canna's Classic Vega and Flores sets are the RTW benchmark, purpose-made for inert media where every irrigation drains to waste.

      From first grow to commercial rooms

      Trichfecta+ by BioMega is the top seller here — a complete set that takes the guesswork out. Step up to Athena's Pro line powders for commercial-scale mixing, or run GP3's three-part base for full control over every ratio.

      Matched to your system by actual growers

      Fourteen years of growing behind every recommendation. Tell us your medium and feed schedule and we'll match the base and strength to suit — stocked in Australia, shipped discreetly.

      Build out your feed room: hydroponic nutrients, coco nutrients, recirculating system nutrients and growth additives.

      FAQs

      Are run to waste nutrients different from recirculating nutrients?

      Yes. Run to waste formulas are dosed for single-pass feeding — every irrigation delivers fresh solution and the runoff drains away, so they're built for stability at the dripper rather than long reservoir life.

      Can I use run to waste nutrients in rockwool and perlite?

      Yes. Rockwool and perlite are inert media, which is exactly what these bases are designed for — the medium adds nothing, so the feed carries the complete nutrient profile.

      Do I need an A and B set?

      Usually, yes. Most RTW bases split into A and B parts to keep concentrated calcium and sulphates apart. Athena's Pro powders and one-part options like Veg-1 by FloraMax are the exceptions.
