Thanks a bunch MVP, I try to search as much as I can, I will definetly try harder.

The construction is preety simple as long as you get the basic idea. I read it over at least 20 times before I started to put it together, just to make sure I know the layout. The instructions he gives are a bit vague so a little common sense goes a long way. Really gotta make sure you get the exact materials he asks you to get. You should be fine. If you're having trouble setting it up you can post in this thread and I'll try my best to help you out.

I'm useing a "Tetra Air Pump" that I picked up at petco. It's a single outlet pump with "up to 20 gallons". I was at the hardware store for at least 2 hours making sure I get my supplies right. Most of the PVC stuff you'll find in one section, the bulkhead fitting your talking about may be a male adaptor, I'm not sure. Can't wait to see your set-up.

I just thought of another question.

What effect would vegging with a HPS have on a plant(s)?
