21h 35m of uninterrupted light later, the plants have mostly straightened themselves back out. I'm considering killing off all of the plants below 4" tall (around 8 of 'em) to preserve more nutrients for the others that are doing well. I'm thinking that at least two of the biggest plants are probably not going to pull through, and if they haven't improved at all over the next 48 - 72 hours, they'll get the Axe. They haven't thickened at all really, and all of them have relatively pronounced white hairs all over the plants, and they're sparkling quite a bit surprisingly. More later...
