OK, so I did watch the video and have a couple comments:
You said 12 hrs on/ 12 off with the light. I don't think that is enough. THE issue for growing indoors is getting enough light. Any amount of light you can give them is so much less than outdoors, that you have to make up for it with more hours. I do 16 hrs on/ 8 off, which is pretty typical. Some people even do 18 on. (24/7 is not better, they do need some rest period.)
Also, I didn't quite understand. You showed the little plant stand with the tray under it and then way up high you showed the two shop lights/ four fluorescent tubes. Where do the plants sit that will be under the shop lights? Not down where the tray is! Light diffuses by the square of the distance. The plants need to be no more than about two inches under the lights.
For winter tomatoes and peppers be sure you read some of the threads we have about it. Here's a few to start you off:

and if you haven't already, do check the seed starting basics thread, there's no reason why you have to figure all this stuff out for yourself! Trial and error hurts when error means dead or not growing plants
