My yellow phals are in a greenhouse where the day temps change from 60 to 85
over the year, they flower just fine. My Phla bellina justy opened, and has been getting a diurnal fluctuation of 60 to 85 daily. Zygos are grown outdoors where nature gives the a fluctuation of 60 to 90 here. I'm sure its cooler at night than during the day at your house too, Ray. K Barrett "Ray" wrote in message ... Pick almost any yellow phalaenopsis hybrid, or ascocenda. I have a Phal. bellina that started spiking for the first time this summer, and it sure as hell didn't get any such treatment. How about zygos? Mine always seem to bloom best in the middle of summer, too. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Books, Artwork, and Lots of Free Info! .

K Barrett "Ray" wrote in message ... First of all, not all plants benefit from a day-night temperature drop, so depending on what you're growing, it might not be an issue. The same is true of high light levels, but if you're sure about that, move them gradually into higher light, or you could be setting them up for significant damage. Having said that, probably the best way to keep critters at bay - short of an enclosure - is the spray periodically with neem oil. It is an "anti-feedant" akin to a true repellant - it tastes bad to bugs. However, if your plants are near a window, leaving it open might be sufficient. (I'm guessing you have screens, of course.) -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Books, Artwork, and Lots of Free Info! . "HFX guy" wrote in message news:39AWc.201840$gE.123319@pd7tw3no... Hi All, So as a Newbie Orchid Enthusiast I have many questions. One of the ones that keeps on bothering me relates to varying the temperature at night for the orchids. I am tempted to moving all of the orchids outdoors so that they get the maximum difference in temperature between night and day and not to mention maximal light. But my biggest concern are the bugs that are out there. How does one go about keeping the bugs (and birds - I have way too many "visitors" on my balcony) away from your plants? Any suggestions will be greatly appreciated! Thanks! Horace |
