I forgot about that cutting above. Its been 19 days. I just checked on it. No roots at all. Bottom 1.5 inches dark with moisture because it was in contact with the soil moist, which has not dried up much at all.
After this much time, I expected to find mold, but there's no sign of any. I left the cutting in the box, but moved it away from the soil moist.
There was no condensation on the lid of the box. My feeling is that it holds water too well and doesn't let the humidity rise.
The ambient temperatur where i root them is about 70F to 74F.
