The Colloidal Silver Generator can be found online and usually costs around $50 to $60. You use distilled water with the generator. The silver rods are attached to the base and submerged into the jar of distilled water. Silver dissolves from the rods into the water. The water is stored in dark brown bottles. This can then be used to mix a spray to mist onto the tomato plants to help get rid of the Tomato Wilt.
Because of the Tomato Wilt, Don is treating his tomatoes with the Colloidal Silver. This is used for bacterial, fungal and viral diseases in plants and animals. Colloidal Silver was used before penicillin came into use. There is no residue and it is not harmful in any way.
