I actually haven't purchased the powder yet. But, I have been looking at the BAS product. It sounds like BAS makes sure their powder doesn't have any funky preservatives. I'm wondering if there might be another place to get it from, but I think a lot of the powders are geared more towards the health food market and might have some extra junk in it that may not be great in gardening. But, I am going off of speculation and based on an interview I heard with Jeremy at BAS and Clackamas Coot.
I wonder if the coconut water sugars might buildup in small tubing or will stay dissolved.
