Research & Development We believe that he who takes the grower seriously, treats the development and testing of a product with equal seriousness. We take as long as is necessary for the development of a new product. CANNA will not put things to market that are not a valuable product for a grower. We try to keep things simple. Growers often refer to CANNA as easy to use. And we like to keep it that way. Our passion for plants is shown in CANNA’s quality products. All of this enables us to offer a product of a consistently high quality.
