Hello everybody,

Do you use heating pads for summer blooming Phalaenopsis during winter? In winter, I have around 19 degrees Celsius during the day and about 13 14 degrees Celsius during the night.

LE: I grow my Phalaenopsis in a mix of bark and perlite and some in sphagnum moss. I have a mix o speciosa, tetraspis, equestris, deliciosa.

Thanks
Anca

I used seedling heat mats last winter over night with my warm growing Phals. The pads clicked on when temperatures dropped below 60F. I felt that it made a significant difference in their health over the winter. My daytime temperatures are higher than yours at about 75F/24C. But my night time winter temps are similar. I am not sure how impactful daytime temperatures at.

What kind of Phals are you growing?

How are you growing your Phals? Supposedly a disadvantage of s/h is the evaporative cooling of the pot and roots, which can be problematic in the winter. So a heat pad would be recommended.

It's only a disadvantage if you are using the technique for warm-to-hot growers and your growing conditions include insufficient humidity and too low of a temperature. I never had an issue with hot-growing phals in my PA greenhouse, but my NC windowsills are a different matter. The slippers are all happy...

If you grow in warmer conditions and want to grow cooler-liking plants, it's an advantage.

I use heating pads for all my orchids here on the coast of the PNW. Air temps go down to 60, but I like to keep the roots warm. I suspect it also helps evaporation/transpiration in my semi-hydroponic media.

This is an interesting post. I grow many Phals. in bark mix, some in sphag. and some
mounted. My temps. dropped to 40F last winter for several hours and my Phals. didn't
miss a beat. As Ray wrote, my humidity is quite high and a lot of air movement.

What brand do you use?

I have used the relatively inexpensive, low-wattage (13w) ones from Hydrofarm intended for germinating seeds. Amazon has similar ones (MET brand, from “Seedfactor”) for $8.99 for a 10” x 20” one that fits in a standard nursery tray.
