Ahhh, you silly man you! You bought that expensive setup and don't even know what to do - LOL!

First off, I wouldn't use that HPS on your seedlings, maybe a MH, but not the HPS. Go get you some Fox Farms organic soil and start your germed seeds in that soil. I like to start my seeds off in 16 oz cups, then transplant in about 2-3 weeks to their final pot. I'd use at least 3.5 gallon pots for your babies.

Also, go buy a PH kit, temp/humidity gauge, some fans, and possibly a humidifier. I think you need to read the GROW FAQ as well, doesn't sound like you have done much research. You will find that a lot people here will not hold your hand all the way though this unless you actually attempt to do a little research first.
