Even when People don't see it they are often stripping the feeder root hairs (roots) off the main tap root. They will grow into the fibers of the paper towel and are ripped off when the towel or seed are moved
I have my strong Blue lights on 24/7 until all of the seeds have germinated and have at least 1 set of true leaves. Then I run 18/6 up to 60 DLI.
That has got to be better than diving into a bunch of Trolls!
