I came by a book on "micro-propagation" once (getting diced up plant samples to root in a petri dish) - it discussed the old fashioned way to propagate orchids (once you have a mutation you like, you have to clone that one plant by however many you want to sell) - apparently coconut water was used as a nutrient medium. Found a source that discusses its use [0], apparently is has beneficial hormones as well, "Besides its nutritional role, coconut water also appears to have growth regulatory properties, e.g., cytokinin-type activity" [0] https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6255029/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6255029/
