Is this all for naught??

A lot of phals only need a cool spell of about 6 weeks in the fall to initiate bloom. So maybe you could set them near a patio door or window from mid or late Sept. for 6 weeks where the temps are cooler. Then bring them back to their usual place and in the spring you may be treated to some blooms. Some oncidiums like a cooler winter and depending what it's parentage is, some need more light but others need less. so you may have to wait and see what happens with that one. good luck with them!

You're way over-thinking this. Phals don't HAVE to have humidity and constant airflow to grow, bloom and be happy. Mine could care less. Would they be happier in more humidity and better airflow? Probably, but that doesn't mean they won't do well without.

It's also a bit early too be looking for new spikes. I usually start seeing mine in October/November. One other thing to keep in mind is that if this Phal was forced to bloom outside of it's normal bloom cycle it may skip a season until it gets back in sync.

My biggest concern would be your lighting. Don't know much about the lights you describe. Three feet away seems like a long way. Do you have a light meter that you could measure light levels at the plant? If it's under 1,000 fc you're going to have a hard time getting anything to bloom.

In regards to the lights, these are maybe 2 1/2ft from the foliage, and the bulbs come from Orchid Web. I spoke with the guy there and these are the latest techknowledgey in LED's. They are designed for lighting higher above the plants. I actually got them when a member here suggested them to me. They are 7w 38diode mr16's with a screw base. I also have with them 2 60diode mr16 chip tech bulbs.
So far I have new growth on all of them, roots as well as leaves. These bulbs are not cheap, but they're listed as being excellent for orchid growing. The web site is Orchid Web, and the bulbs are under "Equipment"

There's a thread on this forum about LED lights you should read. The gist is that they're fine for growing plants, but the spectrum range is not adequate for blooming orchids. Good luck !

It is possible that those lights do actually work for blooming. A guy in our orchid society, Wayne Roberts (Roberts Flower Supply), gave a talk on lighting. He has had great success growing and blooming under some new LED lights that he has been testing. He told us that this is the first (and perhaps only) LED lights he'd actually recommend. He's thinking of getting rid of his greenhouse and growing completely under these lights because of the expense of heating in wintertime. Technology is moving forward! : )
