Provide Warmth & Lots of Light
Most seeds germinate best when the soil temperature is 65° to 75°F. In a cool home or greenhouse, put your seed-starting flats on seed heat mats. Once the seedlings are up and growing, they prefer cooler 60° to 65°F temperatures and good air circulation. A small fan on the lowest setting nearby will help keep them cool and discourage disease.
Starting seeds on a sunny windowsill just doesn't work--there is simply not enough light and seedlings will be weak, tall and spindly. You need grow lights, which you can find at your local hardware store. Hang the lights on chains so you can move them up as your seedlings grow, keeping them just an inch or two above the seedlings at all times for maximum light and warmth.
Put the lights on a timer so you don't forget to turn the lights on for 16 hours and off for eight for most seedlings. Warmth-lovers, like Eggplants, Peppers and Tomatoes, like 24-7 light until they become 'toddlers' able to handle cooler temperatures, so consider putting them on a different shelf without a timer so that the lights are on continuously. ( if you read this carefully you can see words like cooler temperatures when they are toddlers.)
Hope this helps.
