Cut the cucumber into large pieces that will fit through the feeding tube of a juicer. If you will be using a blender to make your juice, then cut your produce into smaller pieces than if you are using a juicer.
If you are using a juicer, then run the vegetable and fruit pieces through the juicer. Collect the juice in a pitcher, stir in the coconut water, and serve immediately.
If you are using a food processor or blender, add the cucumber, pineapple, lemon, ginger, and coconut water to the base. Blend or process on high for 20-30 seconds, or until the mixture is smooth.
Then, pour the blended juice through a nut milk bag, squeezing it from the top down to drain the juice into a pitcher. Discard the collected pulp, or save it and use it for another purpose.
Serve the juice immediately.
