Would this type of grow medium work?

Can i grow my plant in this medium or do i have to buy an additional soil to mix it in. I bought this and some perlite, but not sure if i need to add an additional soil to the mix.

I haven't tried that one but I have tried these with great results.The pro mix is my favorite(extremely light more root growth).Ocean forest my 2nd fav.(great water penetration).Happy frog is great but a little heavy so I added some perlite to make it perfect(Seems to be a very rich mix).
I haven't ordered from these guys I'm just using for reference.

I think the plants would love it either alone or mixed with other soil. Worm castings and bat guano are great for them.

just add water ph balanced and then let that dry completely and you will be very happy,with that soil or the pro no need to add soil to that ,-maybe perilite
