How many did you try?
What method of germination did you use?
Where did you get the seeds from?
marijuana seeds usually sprout very easiy when they are kep moist and warmm
I personally germinate all seeds of any kind in ROCKWOOL cubes.... you just get the cubes soaking wet ONCE (proper pH) and the seeds ALWAYS sprout... from Watermelon to Sunflower to whatever..
