This is a chelating product I use. It makes the various elements and minerals get into your plant much more betterer. It binds with them and "softens" the electrical charge so they can pass through the cell walls and get into your plant. It is used with food to make it more complete, or by itself to give a boost to your plants. The picture shows 2 sides of the round bottle. The order is for 1 bottle. Thanks. Sorry to raise the price (first time in years) but everything is costing more - even shipping to get the ingredients. Still worth it. 2 Bottles ship for the same price as one. Just sayin...
