nothing to be nervous about really. If you follow instructions, you'll grow good weed. A lot of it is just genetics. Most people who suck at growing weed chuck bagseed into soil and buy the cheapest lights they can at home depot. I have friends who try to grow but refuse to pay more than $50 for lights or a fan.
What's your budget?
You need a RED spectrum light for flowering. Flowering is when the plant grows bud instead of leaves. We don't give a shit about leaves so for big buds you need light in the red/warm spectrum. If you HAVE to choose 1 light for the entire grow, get an HPS.
If you have another $120ish to spare, get a 4 tube fluorescent light for vegging. It works great and won't kill your HPS bulb life during veg (the bulbs are rated to run certain hours before they lose lumens and require replacing.)
A fan depends on your watts (light.) Here's an example from a script I wrote. Most of the constants/equations used are from Lucas in an old thread.
This is for a 3x3x6' space with a 400 watt light.
