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
Re: [OGD] ALGAE CONTROL
Hi, Giles. I did not intend to refer to any form of neglect, but when I have seen algae buildup so bad it affects the plants, it's a case of inattention, at best. I have found that a treatment ever 4- to 6 weeks with Physan at one teaspoon per gallon, or liquid chlorine bleach at one ounce per gallon does the trick.

Re: [OGD] ALGAE CONTROL
Ray, are you suggesting I spray the top of my pots and the exposed roots, where necessary, with chlorine bleach at 1 oz per gal? Have you done this without damage to the roots? It is not inattention. Unless I can find a safe spray to eliminate the problem, I think I will try just placing a very lose and dry covering of moss on top of the pot to cut off light to the algae.

Re: [OGD] ALGAE CONTROL
Hi, Cynthia. I grow most of my potted plants in semi-hydroponics using clear-to-translucent pots, and since that is a constantly moist and nutritious environment, algae is a "fact of life". I now use Physan on a regular basis, but used the bleach solution for years with no issue. In either case, I routinely spray the greenhouse walls, floor, benches, plants, and soak the pots. One reason I like Physan better - besides the smell - is that the bleach is a sodium salt (sodium hypochlorite) compound while the Physan is based upon ammonium salt compounds.

Re: [OGD] algae control
Someone here, I can't remember how long ago, pointed out that copper wire can be used to slow the growth of algae. In the trays of water and rocks I put on my orchid shelves to increase humidity, algae used to grow quite quickly. A small coil of standard copper wire in each glass tray has greatly slowed, and in most cases completely stopped, the growth of algae in my trays. I wouldn't think the ciopper would hurt your orchids-maybe you could place a coil of copper wire on the top of each pot the next time you repot?
