We got one of those organic grow-in-the-fridge-and-eat-it-fresh (I don't know what they're rlly called) Butter lettuce heads. It has a bundle of
roots and everything. However, we tried to keep it in water and stick it in the window instead of the fridge (we aren't eating it, its gonna be for the garden when winter's over) Well I discovered (a week later) that some of the roots were molding.

We got another one and I planted it in a clay pot (its in the window too) Which one is more likely to give us seeds? Should I just but the other one in dirt too?
