No rooting hormone. I don't use any. Withhealthy clones, just water is enough. The plant has enough food stored in the leaves to make roots. Just stick the clones in with a very weak fertilizer. Since your clones are so starved, they will need some food right away to make it. No humidity dome is needed with bubblers. Spray with a very dilute (just a couple of drops) solution to feed the foliage directly. Keep out of direct sun or strong light. Fluoros would be good for now. Leave the lights on 24/7. Check the plants hourly, if possible.

Yes, foggers will work, just not for clones. The plants need to have roots first.
