Rhonda was ready for me when I approached her. She had sheets of information and a cookbook to help me learn. She even loaned me a dehydrator in case mine wasn't large enough. The Cookbook she loaned me is called, The Diet Rebel's Cookbook, by Jillayne Clements and Michelle Stewart. You can order it at that link in paperback or on your Kindle. It holds a fountain of information for "eating clean and green" . I used it as a reference, as well as the info Rhonda told me and from all of the YouTube videos I watched in preparation for trying the process.
I sprouted about 9 cups of wheat. I was able to fit all of that in my dehydrator. I have had my dehydrator for a long time, and I couldn't find it on Amazon, but here is a similar one. I don't know if it holds the same volume as mine did. Rhonda had loaned me a rectangular one, similar to this, just in case, but I didn't need to use it. After grinding the wheat and making a large batch of bread, I actually should have dehydrated more than this, so I would have needed the two dehydrators.
The trays in our dehydrator had wide slots that the wheat would have fallen through. We purchased some aluminum screen and cut out liners for each tray. I crimped up the edges to help hold the wheat on the tray. Then, I spread the wheat on the trays, only 2-3 kernels thick, and turned on the dehydrator.
There are many wheat grinders available on the market. I have a Magic Mill Grinder. You can find it on Amazon here. The hopper easily held the flour from my 9 cups of wheat. We also have a hand grinder like this one. It grinds a nice, fine flour, but that would have been a lot of cranking to grind 9 cups of wheat. The electric grinder made short order of it.
