Variation on Sphag & Bag-- attempt to save a phal

[Pilot]

Hi all--

I have a phal "Ember"-- smells like heaven, but has no (well, very few) roots.

I got the plant about two months ago and for whatever reason the roots did not like the treatment they received. So only a few non-rotted roots remain.

So I google sphag and bag and found various instructions on the net but ended up following Ray's advice on how to attempt to save this phal.

I wish I had photos but at the moment I do not. However, because the plant is so large-- I have no bag large enough to fit it without the leaves touching the plastic, which I figure would not be healthy for the leave's tissue. So I set out in an attempt to figure out how to keep the humidity high, the plant warm and in a container that wouldn't hurt the plant with standing water or plastic damage.

Alas, enters a clear storage tub. I have no idea if it'll work but it is the only thing I have available that I feel would help this plant.

So I cut off all the damaged roots and the spike, soaked the remaining stubs and the base of the plant in a Superthrive mix for an hour, then sprayed down with physan 20 to kill off any bad things. I then placed it and secured it on top of an s/h pot with hydroton.

I then put a germination mat on the up-turned tub's lid, placed the plant on top of the mat along with a container full of water and sphag (my aim was to increase surface area, thereby increasing humidity). then I put the clear tub over top the entire assembly. Plugged in the mat and walked away.

Later I came back and put a high low therm inside and found that the box gets up to about 92°F in the day and about 85°F at night and the sides of the tub are dripping wet all the time-- yet the plant itself -- specifically the crown -- remain dry.

So that is my variation on sphag and bag and I would like some input/feedback on whether the conditions have been satisfied to attempt to get this phal to grow new roots?

I should also mention that this set up is on a grow shelf with 6 T12 bulbs on for roughly 12 hours a day.

Do you think it is too humid, considering it "rains" inside the tub? What about heat? Is 92 too hot or is it ok for this type of phal, which if I'm not mistaken, enjoys hotter weather.

Looking forward to your thoughts.
