Hyponex?

Does anyone use Hyponex potting soil? I got a bag from a friend who stopped after his first grow because he wasn't impressed with his time invested:yield ratio. I planted 3 seeds with it and the soil itself seems extremely dense and doesn't seem like it would allow proper drainage. Almost like it's all top soil : /

Anyone have any input / experience with the soil?

P.s. been 3 days since potting and not a single plant has sprouted. the soil is very light colored and thick with lots of rocks and other things. Should I keep waiting to see if they do sprout or just start over with new soil? and after how many days should I see the saplings? My last plant sprouted after 3 days I think : /
