Thanks all the advice everyone. I've got a question about using the cooker though.
Reading the instructions on my pressure cooker, it says the safety valve releases pressure once the cooker reaches 11 psi. When this happens, it says you're supposed to reduce the heat. If that's the case, how can I keep the psi at a constant 11 psi for 2 and a half hours?

keep it where it just slightly hisses out. on my stove with my PC it's usually a hair under 2 on the dial but who knows what yours will be

How do I keep all the water from evaporating? Or is the steam so light that it won't evaporate all of it in 2.5 hours?

Fill the water just under half way up the jars

Fill with water between 1/3 and 1/2 the height of the jars you intend to use. Once you are at pressure, very little heat is required to maintain the temperature, just enough to compensate for the radiative cooling.
Much more and you loose a lot of heat as steam. I go for 1 hour 30 minutes once at 15 PSI and have no problems at all. If you are using at 11 PSI you will want to up the cooking time to at least 2 hours, but 2 and a half would be better if you can stand the wait and tend the cooker.

you should be losing very little water like a cup or two over 2 hours

Uh, no.
Like, an inch or two up the jars is all that's necessary. Hell, like an inch or two, total, is enough. I barely lose any water at all when I pressure cook correctly. I usually fill the water just barely over the top of the trivet, then when I look after, there's still water over the top of the trivet. 
By all means though, use more, because that's better than running dry, but it will affect the efficiency of your run by quite a bit. Steam is easier to pressurize than liquid water.

But more cost effective at one psi cooking 30 gallons of grains in 24 hours vs 2 hours for 7 quarts.

Real research will achieve better results. Use these strips and do a few dud runs. Keep records. Then YOU will know about YOUR pressure cooker.

If those are strips that change at 15psi 121C they'll never change color in a PC that goes to 11psi and not hot enough to change the strips color.
Those strips indicate temperature for sterilization has been met but not that sterilization is complete
