I've tried cuttings from bacopa before, and from what I can remember, I had them covered for about 2 weeks. But, what I do is, uncover them for about a hour or two to see if they wilt or not. If they wilt, then they don't have any roots yet and get covered again for a few days and then test again. And yes, the condensation is a good thing :)
I've always been under the impression that cuttings shouldn't have any direct(hot) light until they have rooted sufficiently or else they'll dry up. My kitchen faces north and that's the window I use to start cuttings. There's still a fair amount of light from the north, but no direct light. This has always worked for me anyway, maybe some others have their cuttings under lights and they do well?

wow, putting cutting under plastic baggies. What a good idea. I have just used the pinch and poke method (pinch a stem off a leggy plant and poke into the soil). The cuttings get wilty for a few days, and then bounce back.
I have put them in my south-facing windowsill with no apparent issues (although the sun in Alaska is much less intense than other places)

I've got some Bacopa cuttings that I've started. I just use a plastic tray which I fill with vermiculite. I wet it with water mixed with "no" damp. I also dip the cuttings in rooting hormone and then cover with a plastic dome. I check it several times a day and use a spritser bottle to keep the cutting moist. I also mix "no damp" with the water in the bottle. Works really well and the cuttings usually start rooting in a week or two. Stan

For cuttings I use the zip plastic bags that sheets and blankets come in. You have to be very careful that the cuttings don't hit the side walls of what ever you use. I usually leave the cuttings in the progator for 10 to 14 days. I just give a VERY GENTLE tug to see if they are rooted...they won't pull out if they are. Another sign is if they show new top growth. The growing medium I use is Promix in 2 1/2 or 4 inch pots.
