My guess is 'cause they can get the orchid grower to
purchase an extra bottle.
What confuses me is the same ratio stated differently;
these may not be the correct numbers, but I've seen
something like: 5-10-5 and 10-20-10. Is the second more
concentrated, requiring more water to dilute? What's the
story here?
