Exciting News!

Keen-eyed readers may have noticed a recent addition to our Rainbow & Brown website: the Gibb-Gro range. Gibb-Gro, a well-established brand in New Zealand for over 12 years, is known as the preferred Plant Growth Regulator. In recent times, Gibb-Gro has diversified its offerings beyond Gibberellic Acid to include wetters, Seaweed Extract, and Potassium Humate. With shared ownership in recent years, we’ve chosen to integrate Gibb-Gro into Rainbow & Brown Ltd. This decision is aimed to streamline operations, enhance our ability to deliver exceptional service and allowing our loyal Gibb-Gro customers to easily purchase the Rainbow & Brown herbicides and other products. It’s worth mentioning that our Rainbow & Brown Gibber 900, BioTreat K-Mate, Seaweed Treat, and SprayWetter contain the exact ingredients of the Gibb-Gro range. However, we now offer slightly different pack options to cater to a wider range of needs. We are still running our www.Gibb-Gro.co.nz website but if buying online we encourage you to buy your Gibb-Gro products from our Rainbow & Brown website www.RainbowBrown.co.nz which means you can order your herbicide requirements at the same time.
