Growing medium?

i grow in soil? and ive just received a cutting and it was in a rockwool cube but it was also squeezed in a 4" by 4" block and the roots were visible coming through it. its one of those orange blocks(ive never used them) . is it ok for me to put it straight into the soil? i no its ok to put cubes into soil but i thought the blocks were for hydro or something?? could anybody please help
ive put it in a pot with bio-bizz all-mix but now im unsure if it will be ok in the block!,

im not sure what your talking about as ive never gotten clones like that.. but i would suspect that u would want to remove any type of packaging that is there just to protect the roots for transportation.. ( u probably want to pull that thing off so the roots are exposed... then put in the soil )

cheers but its too late ive got it in a 12"w by 10"d pot with the soil
its actually like a big rockwool cube but orange i tink they call them slabs or blocks (grodans slabs. they have a hole in the middle and the rockwool cube was in the centre but the roots were already prodding through the bottom of the grodan block or slab
everywhere ive read it says that the slabs are for hydro
