“Ron Peters have asked me to write to you my experience with the Ron Peters protocol.
I
 am Arjan de Gier grower of cucumbers in The Netherlands and the UK ( 
Thanet Earth ), I think you do know my brother Edwin from Prins 
greenhouses.
For many years I have struggled with the green 
mottle mosaic virus in my greenhouses, every year I did more to clean 
and disinfect the greenhouses and every year the first infection started
 earlier and more severe.
At a certain moment the whole 
company is from top to bottom infected with the virus, all materials 
your own car keyboard etc , and then you stop to believe that you can 
ever managed to get clean again.
In 2015 I heard from 
several growers that the Ron Peters protocol really do work, growers wo 
had struggled for years with the virus stayed clean or only had the 
virus by the very back and of the year.
I November 2015 I used the Ron Peters protocol and in combination with more efforts to clean the greenhouses and it did worked!!
In both greenhouses in the UK and The Netherlands we didn’t had the virus in the 2016 crops, we where still clean by the very end of the crop!
This
 is really a big relief, instead that you have to worry daily what you 
have to do to deal with the virus you can concentrate on growing 
cucumbers.
I do know that you have a lit crop but I strongly
 believe that you can only succeed if you clean and desinfect your 
greenhouses all at the same time .”
