I'm planning on growing in a closet soon and just needed some clarification..

My question is: Why are T5's better then say T8's or T12's? T8's and T12's have higher wattage/lumens, so is the smaller diameter giving the T5's a more intense light? Also, I understand you can pack T5's closer together, and by looking at some of the posts with T5 grows they do quite well. But if you where to buy the x2 or even single fixture T8's or T12's without hoods, then mount the fixtures, and make your own hood/reflector, wouldnt this be better? I know the people using T5 setups are generally using High output bulbs, but you could do the same with T8 and T12..... Whats the secret.. lol
