I have just grown some last year's barley seeds for fodder using plain water but the bins had too much mold in them, so the first batch(es) will be composted. Last year I did not have much problem with mold, but I remembered that I used about a capful of bleach per gallon in the water. So I am starting that regime again to see if I can correct that mold problem.I've been alternating between barley and wheat each day. The wheat far outgrows the barley in both height and thickness. I only tried barley because I read on here how great it is.
I reread that you used Hydrogen Peroxide. Do you have any idea if Peroxide or Bleach does a better job on killing mold in fodder? I still have a big jug full of bleach from last year, but if Hydrogen Peroxide works better, I can pick some of that up.
I had great luck last year with barley seeds, but maybe I'll pick up a bag of wheat and try that this year, alternating days like you are doing. I tried to grow oat fodder last year, but that did not work out very well and I gave up on that.
