Thanks for the advice.Mr Grassman
I followed all the steps and am now growing mold free wheat grass.Including using baking soda to wash in the early days as there was still mold on the last few trays of the top watering.
both the headaches and nausea have almost dissapeared.
She did have a couple of fits of nausea,but dont know if it could be attributed to the fact that I used young wheat grass-7 days normally it goes to -9,10 days.Or increase in medication dosage.
It is a releif to see mold free grass used to drive me up the wall,am also getting a much better growth.Using less seed.
Thanks once again and wishing you and all those good souls out there a Very Merry Christmas and a Happy New Year.
