I received my corn a few weeks ago but I have not started the experiment yet. The ears of corn that were labeled for experiment 1 arrived with many of their kernels missing and one of the ears has a small stripe of rotten kernels. The ear with the stripe of rotten kernels is already missing around half of the kernels. It has significantly less kernels than the other ear. I am planning on weighing each cob and that will help to account for some of the difference. But I am concerned that overall this will affect the experimental results. Plus I am a little disappointed in the quality.
