Want to try a new nutrient lineup but not sure where to start? These are grouped together in a kit by the manufacturer, or a "pack" by our staff with everything you need to get started and often include a discount for buying as a package. Some kits are for the base nutrients only, with supplements and enhancers available separately. Some of the kits contain the base nutrients as well as supplements so you can test the full lineup. Check the product description for details or contact us for more information.
