I'm doing the sphagnum moss in a plastic shoe box method for a few cuttings....
I put a thermometer in the box and it's 79 degrees and 94% humidity. Do these numbers matter during rooting like it does once they are transferred to a cup/pot?

Crickets...,

Figfan203,
Yes, IMO, those numbers are extremely important... 72 deg to 78 deg F. & 85% to 90% RH are the ranges that are considered optimal for rooting fig cuttings. Your higher humidity may be of a little concern, possibly that the moss may be too wet or the Hygrometer may be reading high. If you can maintain those Temperatures and humidity at the fig cuttings, with good air circulation, they will root without Sphagnum Moss or Paper.

Once they are rooted and transferred to cups a high humidity is really only needed to keep the mix from drying out too quickly. A lower humidity range (65% to 80%) is needed to keep leaves from drying out if there are not enough roots to keep them hydrated, above that humidity range the leaves may start to rot.

Good Luck.

Hello Figfan203: You have been asking good questions. It may help on some questions, to see where you are located. You may want to add this to your account. You put the information in the signature box.

I didn't really wet the moss that much. I sprayed it with a spray bottle and only made in damp. I have the plastic Shoe box slightly open now to try to lower the humidity. Thanks for the input guys I appreciate it

Figfan203,
Are you are using a heatmat?  If so be very careful not to dehydrate the cuttings. The temperature on the bottom may be much higher that on top and may also account for the higher humidity reading.

I have them above my stove in a cabinet. The stove light puts out heat so that's why it's warm in there
Right now the temp is 73 degrees and the humidity is at 76%

You'd be surprised at how wet you can get it with just a spray bottle.  It may not look too wet, but squeezing it may produce some water.  If it does, it's too wet.
