Orchids on multi-tier shelving units: will lower shelves get enough light.

[BrassavolaStars]

Hello All,

I am currently furnishing my greenhouse. To maximize space to fit my +100 orchids in an 8x12 greenhouse, I have been using chrome-wire shelves like these for my plants.

My question is if the plants on the lower shelves (under other plants which have clear saucers) will be getting enough light.

The shelves are up against the north and south walls of the greenhouse. Most of my plants are cattleyas/brassavolas with some dendrobiums here and there.

The plants on the lower shelves are almost ground level and are not under the shade cloth whereas the top shelf is in front of the shade cloth.
