Pros of a dome in cloning.

I understand that using a dome keeps the environment humid and allows the cut to "drink" through the leafs. Imagine putting a dome over and misting cuts in an ez cloner. Would that make for an even more prime environment for rooting?

You don't need the dome with an EZ Cloner. The constant water to their root area is more than sufficient.

Understood. Do you think adding a dome and misting would increase the rooting speed?

No, I don't think it would speed anything up. You might try some superthrive or something in the water instead of domes and mistings to help move things along.
