I think its planted sprout up!?! I did the same thing you did. I had some stuff with seeds in it... I planted them outside didnt think they would sprout and within a week 3 sprouted... three days later 1 more sprouted! Thats how it all begins... Now, I have an aeroponic system....

I think its a good idea to practice on found seeds vs. bank seeds. There's a learning curve if its your first time and its a lot of work & worry....but
