So i'm not exactly new to growing. I grow with a 400wt MH light <converted from a security light $80> and a HydroFarm Complete 1 Site Drip Hydroponics System.
The system itself is ingenious, I'd never figure out, without it, how to make a drip system using only one air pump.
I use the paper towel method for germination.
I recently germinated 3 seeds. I'll update soon.

So here's my first update,
I finished the towel method, 3 out of 3 germinated in 48 hours.
I used tweezers and placed them in rock wool cubes and placed them DIRECTLY under my 400wt MH

Two sprouted within a day, the third was upside down and aborted.

Now in the pic you notice they are blurry, donations for a new camera are welcome. One's 3 inches one's 2 1/2

They are about 11 inches to the bottom of the MH
See the offbrand ionic breeze.... 25mg of ozone an hour
25mg ozone for 2 plants, breaks down the smells into co2 as far as i know, + + good on both ends of the spectrum and it gives a slight breeze. Any suggestions?

Pictures!!!

light should be closer .. there streching

Yeah mate, btw you're going to need a HPS bulb for Flower.....
but move you're bulb closer but test the heat under it... let the light shine on your wrist... if it burns you its too hot... and when it grows just keep moving it up so it dont burn

and when you spray you're plants, turn your lights off... or they will BLOW up...
