After growing the first few batches of fodder with good results, I started having trouble with white nasty mold. I discontinued growing fodder after I had mold in all the pans. I was reluctant to use bleach in an attempt to stay as natural as possible, but now I don't think it is possible to grow fodder without bleach. When I begin the second attempt, I'll not only add bleach to the original soak water, but I'll also add a smaller amount to each watering.
The second issue I had was the flies. Apparently there were fly eggs that can survive an undetermined amount of time in the grain. Within a couple of days of harvesting the first trays of fodder, swarms of tiny little gnats or midges appeared in the house. I hate flying insects especially houseflies, so I wasn't thrilled with this development at all. The problem was that they were so small that they couldn't be killed easily with a fly swatter. Even after the fodder growing was discontinued, the swarm persisted for weeks. Most of them died by drowning themselves in my coffee<yuck>.
The homestead is growing population-wise with the addition of lots of animals. Most of the animals would definitely enjoy nice green fodder, so I will put the fodder growing back on the front burner soon.
