There's another argument for buying the clearest covering possible and
adding shade when necessary.

I replaced a shade cloth this year because the old one was getting warn out
and tearing and I thought it was going to be letting too much light in. The
new one is of the same density but I was amazed at how much extra light it
is letting in. And all the flower colors are so much brighter!. I hadn't
realized how dark it was getting; as the shade cloth aged it grew dirty and
less light passed through it.

Over the weekend, I pressure-washed the interior and exterior of my
greenhouse. I have to admit that I was a bit sloth in my application of
Physan over the winter (it was too damned cold to go out), but I didn't
realize the degree of contamination there, or from pollution and trees on
the outside.

I have been growing my orchids in the dark!

I'm sure I'll see more blooming shortly...

Don't let this happen to you!
