Nope sorry I don't know much about either product. I thankfully have been blessed with a mite free grow room so far. I did see two mites years ago at my old place once. They were both crawling frantically over a single leaf. I clipped the leaf and flushed it, and have not seen a single bug since. I dread the day they visit my grow.
The tea does not give you the same benefits as in soil, but it does offer some small advantages in addition to disease prevention. The best is being able to forget about water temps. If you can chill a res that's obviously optimal, but most of us have a million other things to worry about first. If your grow room temps are in check then your res should never get above 75, which is a great temp for bennies. Another great thing is not having to be meticulous about light proofing the res. Cannabis roots prefer darkness so you should still use dark containers or cover them, but tiny little light leaks will not cause algae to grow if you use bennies.
You will also see increased root production, a slight increase in water uptake, a slight increase in pest/mold resistance, breakdown of old roots and debris, and Homebrewer said he noticed a slight increase in trich production in his trial thread, though he was unable to tell a difference in potency from the control plants, if I remember right.
