Outside? The mins can get below -15 F in the winter and max out over 100F in the summer. (-26C to 37C) Longer term winter temperatures average around 0-10 F (-17 to -12 C) and longer term summer temperatures are around 80-90 F (26 to 32 C). Fall and spring are also getting increasingly unpredictable with the shifting climate.
My main problem is that I don't have any outdoor space, even a balcony or patio. My indoor temperatures stay around 70 F all year (21C). |

My temps don't go as low as yours, but I just crack open a window in my small office room during November. That lowers the temp enough to stimulate spikes in most of my phals. I have some species phals in another room which doesn't get quite that cool, (fasciata, bastianii) and they bloom too, so I don't think the exact temperature is critical.

Commercial growers do this to get their Phals to bloom for the major holidays. (The orchid that blooms a week before Mother's Day is worth a lot more than the one that blooms the week after) They typically provide heat by circulating warm water under the benches, so it is easy to run cool water for a week or two at the appropriate time. However, for the hobby grower who is happy with blooms whenever they happen, this is really not an issue. When I lived in a condo, I found that I could greatly increase the number of Phals that rebloomed by simply providing supplemental light from the cheapest fluorescents that I could find (just generic full-spectrum bulbs,not grow lights) on a timer 12 hours a day. As the weather cooled, the indoor night temperatures dropped a little, but I doubt very much that it made much of a difference.(I had the same night temperature drop the year before without the extra hours of light and not much happened) It was increasing the duration of light that did the trick. Now, I wasn't trying to time the flowers for Christmas or Mother's Day, etc. as a commercial grower would. But I did get flowers.

Are you trying to induce it to bloom at an unnatural time? Mine always bloom from mid-winter to early- spring. I've got mostly winter bloomers. The only bloom right now is a dendrobium hibiki.

I guess at the moment it's mostly a hypothetical question, based on a gap I've noticed in the material I've found. I've been doing research on Phals because am planning on picking up one or two at the local orchid growers sale this weekend. (Only one or two I say now, but who knows how many I'll end up with). If they're grown in accordance with the seasons, they likely won't be in bloom when I get them and I'm thinking towards how I'll handle blooming them in the future.
That being said....I can't believe I was so wrapped up in my own head that I didn't think to just open a window. Thanks fishmom. Also thanks Roberta for the grow light idea! If I'm getting stuck I'll definitely try that. |
