Hey Bo, if you have it on the walls then it's more than likely on your floor

Better watch out you don't want those Vanda roots turning green on you! *G*
Cheers Wendy

I don't bother. I like the extra stuff on the glass even if it is
unsightly
as it cuts down on light getting in.

Adds to the effect the shade cloth has.

I have a "small" 8ft square polycarb panel greenhouse that every year
needs to be cleaned of algae. I was wondering, as I get ready for
another round of scrubbing and rinsing, what other people do to keep
their greenhouse walls clean and free of algae?
