I cant believe what a bunch of idiots are on here sometimes. The only thing you need to do is keep a bloody paper towel moist!!! How will you look after a plant if you cant do that right? I use this method and know my towel will stay moist for at least 3 days. How?
1. Get 2 pieces of kitchen roll (the most absorbent).
2. Fold into one square and dampen with warm water.
3. place the seeds in one corner of the paper towel, not too close to each other, and then fold the paper over twice, once from left to right or vice versa. Then fold the rectangle into a smaller square.
4. Place the damp paper towel in a bowl, rather than a plate, a bowl acts like a humidity dome and is more effective at keeping a constant temp and humidity level.
5.Cover the bowl with cling film (dont know what you call it in USA) it is also important to block out light so I cover in tin foil also, you could just place a book on it.
6.Place in a warm place, I use my airing cupboard.
I have never had a seed not germinate this way!!! FACT.
