You may think its more efficient, but you gained maybe a day at most by pre-germing them. Then you take into account damaging the taproot if you're not careful. Im 10/10 with nirvana ww seeds stuck straight in soil. And 5/6 with crappy semi-immature bagseeds. Perhaps you're not keeping the soil moist enough for them to germinate. I like to give the soil a misting each day so it remains moist, and it all works out good.
But go with whatever works best for you. I just dont want OP thinking that its absolutely necessary to pre-germ for success.
