Ok my thought is I to put my Orgone Generator Plates in the fridge and it would do all food in the fridge - is this correct?
Yes this is correct. You can also place them on top of your fridge as they will still cover the distance with the energy field they generate depending on what size of the Orgone Generator plate you are using and how large your fridge is.
Note that if you have a very large fridge, you would need the large Orgone Generator plate or a Dome Orgone Schumann Generator to harmonize the greater levels of electromagnetic radiation or electro magnetic fields that your fridge generates.
You say: "However, the small Orgone Generator plate will cover all contents of your refrigerator if placed on a very hard surface such as metal, ceramic or wood." Where would I put it to do the fridge I was thinking you put it inside it there is no metal, ceramic, or wood in the fridge?
You may place your Orgone Generator ceramic crockery, for example, anywhere you desire in your fridge. If there are no hard surfaces in your refrigerator due to everything being plastic, the plastic would work some extent however it would not create the largest energy field possible in order to neutralise the large electro magnetic fields your fridge generators.
You can then place your Orgone Generator plate on a ceramic or metal dish, a small piece of wood or even on some scrap metal if you have any around, to entirely harmonize your entire fridge.
Would the Dome Orgone Generator Or Orgone Generator Plate also cover foods in cabinets next to the fridge ?
As the Orgone Energy resonates out from the inside of your fridge for up to 80 metres for Dome Orgone Generator, for example.
Your Dome Orgone Generator and a large Orgone Generator Plate would certainly cover food in other kitchen cabinets, as well as the area in front of your fridge as this energy sphere is not restricted by walls, wood or anything else, unless encased in solid metal as well as electro magnetic fields your fridge generates.
