okay so in a grow cabinet large enough to hold 6 plants i should leave the fans on 24rs.That means my exuast and my osciallating fan,so were would the temps range from? Because i have a 250w mh conversion and hps but i im kinda thinking about getting a 2 foot 8 bulb t5.Just so i can save some money and not buy a exuast fan just a simple pc intake fan.From what i hear there pretty good for begginers,stay pretty cool and produce some good sized bud.Any opinions if this would be a better choice or should i just stick with the 250 and buy a active air exaust fan for about a 100$ and suck it up.
