Glass jars set with stainless steel rack and ceramic drip tray. I have tried and tested many sets and this is my favourite its easy to wash( a big plus) and simple to use. Sprouts like aflalfa,brocilli, radish are very much part of my lifestyle because they contain a greater concentration of vitamins, minerals, proteins, enzymes, anti-oxidants, trace minerals, phytochemicals, bioflavinoids and chemo-protectants (such as sulphoraphane and isoflavone) which resist cell mutation, expell toxins and boost the immune system. It takes just a few minutes each day to grow your own fresh organic sprouts that will give you absorbable protein, calcium and the highest nutritional value from food. Sprouting seeds and beans are inexpensive and an excellent way to ensure you and your family a good supply of vitamins, minerals add them to juices, sandwichs, salads and meals.
