In a blender, add the coconut water and hemp seeds. Blend on high for 30 seconds to 1 minute. This will create a hemp 'milk'.
Add the remainder of the ingredients to the blender. We use one date but feel free to add an extra one if you prefer more sweetness.
Blend on high for 30 seconds to a minutes. If you do not have a tamper, you may have to stop the blender and scrape down the sides a few times.
Start with a few ice cubes but if you prefer a frostier smoothie, feel free to add more. It will also depend on whether you have used frozen or fresh cauliflower.
