First DWC, Need Advice!

Hi, I have just compiled a DWC and i was wondering if there was anything else I'm going to need? i have a basic picture of what the operation looks like. Im trying 2 grow 1 LARGE indica dom. plant. Once again this is a first time thing, any suggestions? does this look correct!?

Supplies:
One 5 gallon bucket
One Air Pump
One Net Pot
Two Air Stones
Two Lengths Of Tubing

Your going to need to buy a ph and ppm meter and it would be smart to get a water temp. meter as well(you can get them all in one). Some things to leep in mind with hydro is water temp. is best around 68 degrees F, 75 and below is usually good. Also, the more air bubbles the better, I've seen the difference in one air stone in a bucket to two in a bucket. No light should reach the solution at all or you may have problems as well. Any other questions?
