What if i soaked my seeds for 24 hours in a glass then put them in a small container in a dark place till they came up?
Many people do this and have good success. However, I find no need for the extra step, since they will be soaked in the dirt.

Should i place plastic wrap and rubber band on top?
No, unless you like battling mold.

Do i need a fan hitting the soil and keeping it dry
Follow my steps above and you will not get mold. If you are worried about it, after watering, spray the soil with Serenade or some other anti fungal and repeat every other day or so. A fan is important for several reasons, though I have had several success stories with out them. If you have very low humidity and at least a little air flow throughout the grow area you may find that you can get weed without a fan. However if you can keep your plants gently rustling in a breeze they will be much stronger and healthier overall. Some studies indicate that your plant will grow twice as well if you have a strong breeze on it at all times.
