100% growing newbie, need help for microgrow

Yesterday I got some weed seeds (about 10-15) off a friend, not sure what type they are but I intend to grow them and save getting ripped off all the time. I only want enough to fill my own needs and maybe a couple of sessions here and there with good mates. I want to keep it as long key as possible (very very nosey neighbours and occasional guests) I have a pc tower about 15-16 inches tall, 17-18 inches long and 5-6 inches wide to play around with. I'd really appreciate a step by step guide from germination right through to the harvest of the good stuff. Id like it kept as simple as possible but also reasonably stealthy and relatively low cost. I also need it explained in easy to understand terms as I did a whole bunch of reason on it today and last night and all the abbreviations and names and everything confused the hell out of me. I don't need it to be world class bud, just a half decent smoke that will give me a good buzz.

Thanks

I was thinking rather than buying all the stuff if there was stuff around the home I could mix up. Like instead of buying purified water, I could use boiled water that has cooled to room temperature. Instead of using expensive high grade potting mix, maybe just a mulch/compost/worm farm mixture or something. As cost effective as possible

cheaper to just buy a bag of mix from HD.
Why buy water? Tap water works. PH balance

How about lights and stuff, if got a few incandescents and a few fluorescent bulbs laying around. Which ones should I use?

I've done a cheap grow, the results were not that great but here is what I did.

Germinate seed in paper towel.
Plant in solo (red plastic cup) cup with holes in bottom.
When it got larger, a month or so, I planted in a cheap plastic 2 gallon pot. (found anywhere)
The soil was a 6.00 dollar bag of miracle grow seedling stuff. You can use any bag of potting soil, preferably without additives. (cheap and easily found)
I used tap water.
For 2 months I used this every other day while keeping the lights on 18 hours per day.

After 2 months I used this every other day and kept the lights on for 12 hours. (plant must be a completely dark place during the time the light is off)

For my lights I used something like this



The bulbs are 6500k cfl bulbs. See the light bulb section at any home improvement store. 5500k will work. These bulbs will be used for the vegative growth stage. Lights on 18 hours per day.

When going to flowering, lights 12 hours on, you want 2700k cfl bulbs to replace the 6500k bulbs.

The pc case is not going to be tall enough.
Use a cardboard box and line the inside with an emergency blanket. They can be found in the sporting goods section of department stores, about $2.00 USD

Use spray on adhesive to make the blanket stick.

Hang the lights upside down by making a few holes in the box and pushing a tube of pvc pipe or a small wooden rod through. You will have to really watch the temps of the box and probably have to make a door and leave it open when nobody is around. During the 12 hour dark cycle, close it up and cover with a heavy duty trash bag.
