Is this a good mix?

[(..._...)]

Hi
I just ordered my first cym, a large seedling, and would like to know if my media will suit the roots well. I purchased a bag of medium sized bark and coconut husk mixture, (50% each).
If this mix is okay, how long should I soak the mix. ( I have heared coconut huks needs a lot of pre soaking before use)

Thanks! Wish me luck!!
