Is it possible to premix a quart or half gallon of Biotest Superfood in a blender and then store in the fridge? Does this affect potency, shelf-life once mixed & chilled...etc.???
Not the best idea, the water will dissolve it over time.
Why would you use a blender?
This stuff easily dissolves in water.
Of course water affects storage life. Keep it at most 1 week in the fridge to be safe.
