Welcome to the group!

If we want to be picky, we can safely say that using coconut products isn't truly a "natural" way of growing them, as the are no orchids that grow that way naturally. (When I routinely gave lectures on semi-hydroponics to orchid societies, I often heard "it's not natural", so I simply asked when was the last time that individual had seen an orchid growing in fir bark or coconut husk chips in nature?)
