Sally,

The fact that you're trying semi-hydroponics is essentially irrelevant to getting it to recover. Consider the following:

1. Immerse the entire not-yet-potted plant for 1-2 hours in a 1 tablespoon/gallon Kelpak solution.
2. Pot it up however you plan to grow it, long-term. S/H is fine if your conditions work well with it for something warm-growing like a phalaenopsis.
3. Water it in with the Kelpak solution.
4. Invert a clear plastic bag over the pot and plant to trap humidity, but don't seal it. Without roots, the plant has no way to take up water, but still loses it to transpiration. Maximizing the surrounding humidity slows that.
5. Keep it very warm (use a heat mat if you want) and shady.
6. Don't let it dry out. Use the Kelpak solution as needed for the next month.

In about 4-6 weeks, when new roots have emerged and are growing in the potting medium, remove the bag and return it to your general growing care and environment.
