“Soakers” are all double duty. The suggested use indicates an overnight soak in water. That water is now colored and flavored and best used to moisten any prepared diet items (ZooMed pellets for example) you use. You don’t loose any water soluble vitamins, and create more day to day variety. Hibiscus is the most dramatic giving a deep red, while Rose Hips give a lighter shade. HoneyBush smells very sweet and imparts a different red than hibiscus or rose hips. Rooibos has an earthy floral smell, and a slight red to it.
