using spagnum peat moss

Have anyone used just spagnum peat moss. i used it for sunflowers, i grew for my wife. the roots were incredable for the sunflower. it seems that the sunflowers really like it. the spagnum holds moisture well and drain really well.
soon i will use it for my growing as soon i have a seed open up.
just interested in if anyone
tried.

i use it about 20-30 percent and perlite and organic top soil
