Hydroponic nutrients

Whakatupu Nutrient Range

Locally manufactured by a team of hydroponics experts at Ōtaki Hydroponics. Our special blend of nutrients supports fast-growing productive crops.

“Whakatupu” means “to rear, grow, raise, cultivate, produce, farm” in our native reo. We strongly encourage all hydroponic gardeners to give the Whakatupu brand a try. We are confident you will get the same great results as past and present Ōtaki Hydroponics’ customers have been achieving for over 25 years.

Otaki's little secret: The Whakatupu range is the Toyota Corolla of hydroponic nutrients.

Very reliable, low cost and gets the job done with great results.  NZ made. Value for money, by far, the best nutrients in New Zealand.  So why not support local and save money at the same time.

"After almost 30 years I still rely on Ōtaki Hydroponics general nutrient to grow tomatoes and cucumbers every season. It’s what I recommend to my friends who are giving hydroponics a go for the first time."
