Hi
I am by no means an expert but this works quite well for me.
The seeds should be fresh and of good quality, I use a sterile seed starter mix, some people use vermiculite, but for me my seeds start quicker in moist sterile seed starter. I put the seeds in clear tuperware containers with lids containing this mix, moist but not saturated.

I have a 20 gal aquarium covered with a plywood lid with a heat mat inside. I keep the temperature around 85-90 f. and my seeds germinate quite quicky depending on the type and quality.
