How to grow sturdy plants from seed


I have planted lupin seeds in my greenhouse and they are now  got past the two leaf stafe and have proper lupin leaves. They are about 3" tall but stem look very frail.

What can I do to make these plants thicken out and produce sturdier plants.

    They need to be out in the fresh air getting lots of light and fresh air ... pot them on and put them outside somewhere bright but not scorching sun and make sure the slugs and snails don't find them.
