Dude, I think you're getting a little ahead of yourself. Especially being one of your first grows.

I just went thru this thread and im not surprised.. You're getting all kinds of contradicting information.. most of which is from another beginner...

Keep it as simple as possible:
1) LIGHTS
2) SOIL/NUTES
3) VENTILATION

Thats it.

A weed plant can get by the first 5,6 sometimes 7 nodes on merely 1/2 strength of a cheap root stimulator nute: ie. Schultz Starter Plus (5-10-5).

Just some Ideas:
- Flat white spray paint = 1$ (No foil, no mylar)
- 2 max CFLs until bigger
- That bottle's dents are gonna make it hard to transplant. Also, roots dont like light = wrap the soil part of the bottle in black tape
- Is fan exhausting? if so, a simple extra hole can then act as the passive air intake.
