Something weird growing in 33% D2O

Looking over the data for the Repeating Crumley experiment I came across this. Typically while I count seed germination I put previous days in sequential order with the current set of pictures. This helps me to identify which seeds have changed (like time lapse). Looking at Day 6: 33% d2o tobacco seeds, I saw the above image and went back to see what happened in Days 4 and 5. Sure enough, the “fog” that is growing from that one seed was growing from the previous 2 days.

While the control is ok, I’m wondering if this is root hair or mold. It certainly can be mold. Looking at this makes me think I’ve seen this in previous trials of this experiment. And from what I’ve seen, it certainly doesn’t hinder the growth of the surrounding seeds. Especially since they’ve already germinated and they’ve been counted.

Just something to keep an eye on though.
