Info needed please! Can You Help?

Hello! I am a student at the Agricultural and Food Sciences Academy (www.afsa.state.mn.us) in MN. For my science project, I'm finding out what materials hold heat in a greenhouse better. I am starting marigolds from seed that someone is sending me in plastic peanut butter jars (my greenhouses... real technical, huh?).
What is the best type of soil for growing seeds? How much soil should I use? I'm thinking of having 6-7 seeds in a jar. Should there be more or less? Will marigolds grow well under full lights? Should I water from the top or the bottom of the jars? Do marigolds need nicking/scarring/etc? How/why does a greenhouse work? Should I have a cover on the jars, or have them open? Should I have my heat keeping materials in the greenhouse or on it (i'm using a control with no material, wood, tinfoil, water, brick, sand, and rock)? Do they need a fertillizer, or will they grow in the soil by themselves? What should I do with them when my experiment is over? Should they be seperated then? Will they survive left alone on weekends? Anything else you can tell me?
Please reply to my email, lmeyer@agacademy.net, and leave your name so you can be credited as a resource.Thank you, Laura in MN

    Laura,
    There are some great files here in the Article library. For example, all you need to know about seed starting mixes is in the article here.
    Let me know if you need help finding more, or if you have any questions after reading them.
