In the blender, add the watermelon, cucumber, and mint. For a smaller blender, you can do 2 batches.
Put a mesh strainer over the opening of your jar and slowly pour in the juice. Use the back of a wooden spoon to push the juice through the strainer. *see note below on this step
Squeeze lime juice into the pitcher and stir.
Give it a taste and see if you want to add your sweetener of choice.
Add water to fill up the pitcher or jar.*see note below on this step
Chill 30 minutes and enjoy.
Notes
*Note on Step 6: You can totally skip this step if you want a thicker juice with pulp. If you do, I suggest blending it again with ice and drinking it like a smoothie. *Note on Step 9: I did it in a gallon sized mason jar and it ended up being a little less than 1/2 gallon of water. The 1:1 ratio of juice to water does not change if the size of the container changes. To save on fridge space in the past, I have also made it where I added the water as I poured it into the glasses.
