Well the trick is really the potting media. Make sure it is moist but not too moist. The technique is to measure a loosely filled cup of potting media. Place about 1/3 cup of water. Then mix it, and squeeze with all your might and collect the water. The potting media that has been squeezed will have the ideal moisture content for rooting. Now measure the difference with the 1/3 cup of water and what you squeezed out. It varies with the status of potting media, so I can't give out a standard formula. In my case, I end using a net amount of about 1/8 cup of water per cup of potting media. I then used that to mix measured amount of water with so many cups of potting media, without the need to squeeze them, just mix nicely. I spray the measured water while mixing the media.

The next step is to dip the cuttings in rooting powder or gel or whatever rooting hormone concoction of your choice. Then insert them in the cups that contain the potting media.

Then line up the cups inside the translucent container. Seal everything with Saran Wrap if you don't have a translucent cover. Well, I got the container on the cheap without the cover, so I use the saran wrap. I secure the saran wrap with tape. You wouldn't need to water this for about ten days. Place the setup in the warmest part of the house, partially or indirectly lighted by the sun, not exceeding 90 deg F of inside the chamber temperature.
