plants dying HELP

i planted some seeds in little dixie cups two weeks ago and they have gotten to be about 5 inches tall with little leaves growing on top. one of them got too top heavy when i was sleeping, bent over causing a crimp in the stem or whatever you call it and it died. i think the next one is going to die as well. how do i keep my plants from becoming too top heavy and falling over and dieing

i really want at least one good plant by the end of the growing season


help please

need more specifics like what lighting and stuff

five inches in a dixie cup? i'm not a pro, but you should probably move them to a bigger medium.

Put them into bigger pots without messing with the roots too much.
plant them all the way up to the leaves.

im not a pro but sounds like your light is not strong enough or not close enough to t plants, depends on the lighting like t other guy said
