Do cuttings like it humid?  I've got them in a clear tupperware and am noticing condensation at the end of the day... not too much, just a light mist about halfway up the side of the tupperware.  Not sure if I should pop the lid and let them air out or what.  Thanks!

Greetings

Yes, cuttings like high humidity. Some signs of moisture on your container's walls is a good sign, but you initially want high humidity and slowly introduce to normal conditions...

DITTO to the above

If doing cups I usualy turn one upside down on top for a dome. Only thing is watch for signs of mold. Let it air out a few tims a day. I also start some in the bathroom. With a family of five taking steamy showers they get all the humidity they need in there. Third option and I use in my other rooting area is just a spray bottle of water. A few squirts while checking them seems all needed.

I was measuring a relative humidity last year in a bin, it was between 75 and 90 %. The cuttings were happy, I also saw some condensation. In addition, I had a heating pad under the bin.

@ SCfigFanatic, May I ask where to buy a mini-greenhouse like yours? Or how to construct one?
Moisture is hard to maintain in my area, so one would gladly be appreciated. The winters here are quite shocking to plants, as they can drop temperature without warning.

Love Dan's Humidity Green House....I need to get going on a similar set-up.
