I am trying Azurepowers superfast colinization recipe and i was wonder how long to Pressure cook the jars? Will an hour be fine?
The mix is 1/8 cup quinoa, 1/8 cup whole grain rye flour, 1/4 cup vermiculite.

One hour at 15PSI seems safe. If you want to be super careful let the jars sit out for 12-24 hours before pressure cooking. This allows any bacterial (or other) endospores to germinate and be killed by the sterilization process. It is not necessary but may help if you experience a lot of bacterial contaminations.

I read that suggestion somewhere, I thought it was only if your using whole substrate not a powder, or is it in all substrates?

Its a general suggestion for anybody that is having trouble with contamination regardless of substrates. Spores can be in flours as easily as whole grains.
I don't know why, but here is my guess. People that are using whole grains are generally a bit more experienced and using more substrate at a time. More substrate equates to a larger initial endospore load. Larger spore loads mean more chances of contamination. To help tip the odds back into the bulk growers favor, presoaking is used.
There is probably a more scientific reason, but in the end who really cares. If you are having problems, presoak. If your not having problems, why change? The way I look at it, one day lost to presoaking is time well spent if it helps to protects two months worth of investment.
