Hi, Gannet: Sounds like your balcony has a solid roof? If so, I'm
surprised you feel the need for additional shade for "high light" plants.
Personally, I'd worry that you wouldn't have enough light to get, say,
vandas to bloom well, before adding more shade ...

But in any event, yes, 30% shadecloth is supposed to block 30% of the sun
and let 70% through.

Good growing,

This will be for the South-facing balcony of our apartment. I'd like
to get two panels for the railing, and two panels for the space
between the railing and roof, all with grommets for adjustability.
Hopefully that will let me balance things so I can make better use of
my space.

One more question, though. Charlie's lists the cloth as 30, 52, and
66%. I infer from the listing for lath cloth that this is the
percentage of light blocked, but it's not stated explicitly. Anyone
know for sure?

I'm looking for just enough block to let high-light plants take midday
Florida sun. I'm thinking 30% block should be good. Anyone agree or
disagree?
