No need to worry about hermies right now. Focus on keeping them alive, happy, and growing.

If the sprouts are in the bathtub, that may be too cold for them. Put a book underneath the cups, because the bathtub is colder than the air temperature, and you don't want to let the roots get cold. The lights will keep the above-ground part of the plant warm, but if the roots get cold, it will stunt growth or possibly kill it.

Good luck getting it set back up! Spark one up while you work...it'll make it more entertaining
