Dude. You can easily plant that seedling still. Smarten up and check your germinations more often buddy. Clearly you left it in paper towel long enough for it to root in to it. Very stupid to let the bare root be seen by light. And taking pictures. WTF? Probably killed the, poor lil bastards...
I had a few plants like that, didn't seem to matter to much, i noticed the rain would gather in the hole sometimes, but it just seeps through the dirt, just keep a good eye on it. How big will the plants be when you transplant?
If you were going to get raided and they found your grow area anyways and search every where else and find where you shoved the pot plants you're just going to get charged with trying to get rid of evidence. If you put yourself in the position to get caught "Shitting where you sleep" sorta speak...
hey man i had 3 plants in 5 gallons a few years ago, watered them friday afternoon, And went back Monday mid day. 1 plant was deader the dead, and the other two weren't much better, 5 gallons are good and all but you gotta water them a hell of a lot.
I'm working on a way to set up a drip...
