I too grow some orchids in semi-hydroponics using diatomite and clear pots, which make it easy to check the water level, but will allow algae to grow all around the exposed side and top surfaces. "Fact of life" is correct. However, since I have set the clear pots inside a slightly larger green flower pot , I have totally eliminated algae from the pot side and only get a few spots of algae on the top surface. Algae is no longer a problem and there is no need to spray. peter . _______________________________________________ the OrchidGuide Digest (OGD) orchids@orchidguide.com http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com
