I would doubt it's any appreciable impact on the plants.

Just another thought on algae..........It is alive & growing, so it's
using
up the oxygen
that the plants need? Yes?

Unfortunately, algae is a good attractant for snails, slugs, and all
sorts
of bugs - nothing like a nice fresh salad!

If one thinks that that's good, as it will deflect the advances toward
your
plants, forget it - it brings them right into the vicinity.

And as Wendy said, if it's on the GH covering, it will be elsewhere
eventually. I emptied my greenhouse this summer in order to power-wash
the
thing - covering, inside and out, structure, benches, RO unit, water
tank -
you name it. What a LOT of work! You can betchurass I'll do a better
job
with the preventive sprayings from now on!

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.

news 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?
