Mycorrhizae are awesome. Without them most species of pine tree couldn't survive. The key to implementing them right is to make root contact with them. If you do DWC manually topfeed some R.O water with mycos in it. If you do aero/flood and drain/drip system simply mix the mycos into your solution. If the mycos don't achieve root contact within 24 hrs they're probably gone.
***** If you use chemical fertilizers I would highly recommend something that is at least "derived from natural sources" like botanicare pure blend pro. I did a side by side test. Myco vs. No myco with General Hydroponics. (Run lower PPM range with chemical fert or the mycos won't survive). Myco plant was slightly larger on top but the root mass of the myco plant was 1.5x the size of the non myco. Inoculate from seed/cutting and use until 2-3 wks before harvest.
Oh yea and you only need like 2 Tablespoons per 50 gallons. I think they recommend a lot more on the package.
