I get asked this question all the time and my answer for 2015 is 14-16 hours of grow light with bulbs that sit about 1-2 inches above your seeds or plant seedling leaves. Bulbs vary, so pay attention to heat coming from the bulb so you don't damage your plants. If you don't have enough intense light, your plants will become what we call 'leggy'. They will be tall and spindly and they are basically putting all their energy in stretching to the light, instead of growing strong and stocky. 'Leggy' plants make for poor transplants. Once your plants are established, lighting is more forgiving.
I also get asked if you can start seeds on a windowsill. My answer is NO unless you absolutely have a south facing window that gets full DIRECT sun for 8-10 hours. If you don't have this intensity of sun, your plants again will become 'leggy'. You have to be able to look out and see the actual sun from the window.
Here are some videos that explain lighting and tell you what type of bulbs to buy. Incandescent bulbs got to hot. You don't need special grow light bulbs. They are no better than what I describe and they will cost you more money. You can mount them in closets, create grow light stations or even use storage totes to build grow light boxes. I recommend you start small and give it a try. You will be surprised at how easy it is. You can find a lot more videos on vegetable plant lighting and designs by searching my YouTube Channel.

You will notice I vary my starting mixes in different videos which is really due to just trying new things season to season or finding products on sale. There is no perfect mix or exact recipe. You do not need to spend a lot of money on mixes. The key to starting seeds indoors is that the starting mix needs to be sterile. Never bring in soil from outside. You will be bringing in bugs, fungus, disease and disappointment. You can buy starting mixes that are sterile at most do-it-yourself stores, Walmart and nurseries. Check around and see how prices vary.

I am often asked how often do you water your seed starts and the answer really is when they need it. Too many factors come into play that don't make it possible to say when and how often. But the guideline is less when seeds are starting and more when the plants are bigger. The tip I have is to look at your starting mix and notice the color when it is dry. This is typically how it looks out of the package. When the top of your seed cells turn that color... you are ready to bottom water your seed starts or transplants. The top of the starting mix will always dry first.

Germination and Feeding:
Seeds germinate at different rates. Some will germinate in under a week and others can take up to four weeks. You can find that information on the seed packet. Basically just follow the instructions on the seed packets timing and planting depth. Generally speaking the temperature should be in the 70's (Fahrenheit) for germination. You can purchase a heating mat if the area you are using isn't getting into the 70's. I have tomato varieties that need high 80's for good germination but in general you want a 70+ degree seed starting area. Remember the lights will add heat to your germinating seeds.

Think fish fertilizer, beet extract or other organic fertilizers that not only feed your plants but create a friendly food source for fungi and bugs. This is 100% my opinion but, what every you choose, use a liquid fertilizer. You can also initially throw in a granule type fertilizer into the starting mix when you are preparing it for starting your seeds. Again, use a lot less in the starting mix. More harm can come from over doing it with fertilizers.
At some point you will need to move your seedlings into larger cups. This all really depends on what you are growing and when you started them. The key for starting seeds indoors is to grow a nice size healthy transplant that hasn't sat in the house too long. You don't want your plants to be flowering indoors. If that should happen, remove the flowers. You need to time your seed starts, so they can go outside when the conditions are right. That is typically after the last frost date in your area. Most seed packets will tell you when to start seeds indoors.
The general range for starting most seeds indoors is 6-8 weeks. There are exceptions. Many herbs can be started 10-12 weeks indoors. Squash, cucumber and certain melons should be started 4 weeks indoors. Again the weeks time is based on when they can go outside, free from risk from frost. However, some plants like warm weather, so you need nights that stay if the 50's. If you put a warm weather plant out too soon, it just sits there. Do a search on cool weather crops and warm weather crops and that will help you understand when to start them indoors as to match them with the outdoor conditions they like.
