Some of my tomato seedlings are doing some crazy stuff. This one is A Grappoli D'Inverno. I have some Amish Paste that did the same thing. I germinated under a humidity dome at 82-ish. These seeds popped quick and shot out like silly string. As soon as they pop, I move them into a light chamber with plenty of light.This one is probably 5 days post emergence.
What causes this? Some of my starting containers have a normal sprout along with one of these string plants.
Should I just go ahead and plant this one deep?
That's a shiny quarter in the picture for size reference.
