The roots on your plants may be "white", but do they even remotely look like these?

Notice they have green tips.

If this plant doesn't work out for you, may I recommend a few different kinds of Dendrobium, I think you might enjoy, and in which I think might be easier to grow...

Try looking into:

Den aggregatum
Den farmeri
Den thyrsiflorum
Den. unicum

These also happen to be fragrant.

I forgot to ask...

What kind of water do you use to water your orchids?

Tap?
RO/DI (reverse osmosis/distilled)?
Distilled?
Filtered?
Rainwater?

Do you know how cold your water is? Are you able to get a reading of the water temperature with a thermometer?

Are you using ice to water your plants?

I have a thermometer which is why i was so certain about the temperatures. I may be allowing the plant to dry out a little too much possibly but definetly not watering it too much and no it doesn`t sit in water. I check the chid every day to see how its coming for wetness then once i think it is dry i usually wait another day to make sure and then water it. maybe thats wrong but its hard to tell and all the sites i`ve checked say to wait another day if unsure. Surprisingly it still has some leaves though.

I would love to buy a humidity meter but we are moving within a month and we`re down to wire as far as money goes but after we move i will surely get one. actually wanted to a couple weeks ago but the store was out of them so i couldn`t. Plus even if i did buy one now i`d just have enough time to figure out what to do before i would have to change it again once we moved with the roots still being healthy it seems silly to me to do that only to make it go through more changes in a month or less. But I probably will treat it for infections because I don't want that to spread through the plant.

I think the next place is much dryer since we are moving into a friends house for more financial stability for the both of us I took my bamboo over early and it has used 4 times the water it normally does since i left it over there (went over and checked on it). Any suggestions on what I should do for the new environment it will have what to check, that sort of thing? Which type of water is best for that type of chid? I haven't been able to find any information on that. So i will change it to whichever if necessary.

ICE??? people actually do that??? I know they sell orchids and claim u can water them with that i bought one of that kind but don`t actually do it. I use water that is neither hot nor cold to my wrist.

look dormant to me. no green just white.

If where you're going to move next is that dry. I highly recommend a humidity meter (which you've stated you're going to look for).

Then there's a cool mist humidifier. They aren't expensive either (should cost around $25).

In the meantime, if you gotta water more often, then water more often.

Maybe your plant is just losing old leaves. It happens on Dendrobiums quite often. What you may be thinking are new leaves may actually be the most recently grown leaves on a very old cane.

Also, once you've moved and settled in a bit, should you need to, post questions again. The new place may be radically different in a lot of environmental aspects.

[Sandrilene]

Yeah once I'm in there I'll probably post what the humidity is and other conditions so you will know and be able to make them better for my chids. Whatever it was doing with the leaves has slowed down quite considerably I am still going to treat it for fungus though and try to find a better sized pot. The one it is is was just an emergency switch due to fungus gnat infestation I had to repot quite a few of my chids and ran out of the right sized pot couldn`t put it back couldn`t leave it with none so shoved it in a butchered container. lol. I should have a ton of different light choices for them at the new place tho there are 3 different directions of windows to choose from (score!).
