I love when i come to threads like this........I'm proboly the biggest noob about all of this growing stuff, i mean shit i got like 50 posts if that, mabey more by now, but i actually have the inclination to go search for the shit i want to know and not just ask people then wait around and never find what i wanted to know........its just so damn easy to just ask.......no leg work, sit back and let everyone do the legwork for you, then get pissed because no one answered your question in 5mins.
Have the mental fortitude to go figure things out for yourself.........and not have someone hold your hand.....
Whats bad though is that immature people generally are the ones who ask the straight forward questions, then get all pissy that no one answered them, definently shows age, or lack thereof.........all the info is at your finger tips, just learn how to find it.
Go to yahoo, type in ballast, or even "what is a ballast", simply done.
Forums are made for the wealth of information, and the discussion on the wealth of information they contain.......why dilute the good information with idiotic threads that are repeated 20 times a day.... just search. thats all.
