Thanks for the replies guys. I figured it out, I made my own drip ring but it didn't really work. So I played around a bit and found that there wasn't enough pressure in the line."the holes were too big" I reduced the hole size and bingo.
Here's some pics of my first hydro unit, hoping to have it up and running with my first grow in a few weeks. All I need to get is the nutes and order my beans. Any quick advice is welcome. Thanks.

Wierd...I can't upload pics..? Never had a problem on other boards before...HuH. Oh weel you've seen one you've seen them all.
