Starting plants from seeds
You are growing them without sufficient light. Tiny seedlings need very intense light if they are not to get tall and "leggy." You need a grow light, which can be something as simple as a tabletop fluorescent lamp that you can get very close to the top of the seedlings -- an inch or less away. Move the light upward as the plants grow but keep it very close to their tops. You can rig up shop lights to do lots of starts at a time. Check shop.bhg.com for seed-starting equipment you can buy.
