Yea,I planted 4 or 5 and got 1 seedling and 1 popped,the other 3 same happened as you,the seed shells are that tough.im just back to it after about 2 yrs so I didn't hav all the bits and pieces I normally would hav when I germinated them.im just waiting on a delivery now with superthrive,liquid oxygen etc.when I pop the other 7(which will be soon)I'll hav everything I need for it.did u find out anymore about them?,all I know is they're legit,97 ssh made by toxic hippy gear.their was a pack of first release mr nice nevs haze(yellow pack)at the auction that day,13 seeds in it,I went back for it a little after I'd got the ssh and it was gone,kicking myself now,76
