No you do not need to germinate ,i use to but don't anymore as i have got a 100% sucess rate with just putting the seed in the soil .This is how i do it.
1 fill pot with soil
2 water the soil with luke warm water
3 get a pen and make a hole in the soil to the depth of the metal nib of the pen
4 drop seed in, any way it falls is ok
5 lightly back fill the hole,covering the seed
6 spray the soil with water to wet it down
7 put in a warm place.I grow in my closet so i just fire my hps on for 18 hours a day ,i live in a cold climate so i need to do this ,it's cheaper for me to run the 250 watt light to heat the closet up than it is for me to leave my heating on all day.You may be fine depending where you live..20 degrees or above is probably fine...i think i read 25 is optimal
seeds normally show up on the 3rd or 4th day ,like plant on monday sprout on thursday or wednesday.. yet to have a failure doing this.When you think about it ,this is how shit goes down in nature.No paper towel fairies in the wild.. i don't think ,i could be wrong.
it also eliminates the chance of you damaging the taproot when planting ,It is a weed of course so both ways work.but i find it easier doing it like this now.
