Moisten your mix with tap water or reverse osmosis (RO) water. If it gets too wet add more dry mix. Then put the moist mix in a deli container or small pot so that the mix is around 1 inch deep. Keep the mix covered and moist until you sow the seeds.

At a table, place a sheet of computer paper in front of you to catch stray seeds. On top of it put an index card or paper of around that size. Open the glassine envelope and slide/tap the seeds onto the smaller paper. It might be necessary to pull the glassine apart to get all the seeds out. Then move that smaller paper over the sowing surface while tapping it to make the seeds fall evenly over the surface. Enclose the sowing container in a transparent sandwich bag or similar and fold its flaps under the container.

Place your sowed seeds container under “good” light, with the sowing surface at around 9-12 inches below the light. Fluorescent or white LED lights work well. Use a 12 ON, 12 OFF light cycle. Weak window light will produce leggy seedlings that are difficult to work with. Under the conditions described above, moisture will condense on the inside of the bag within a day or two. If it does not, it means your mix was not sufficiently moist at the start. To fix this, temporarily remove the bag and gently mist the surface with tap water or RO water. The seeded pot should stay enclosed in its plastic bag until the seedlings are large enough to transplant as described below.
