There has been a lot shit being talked about HO t5's and weather they are any good or not. For those who do not know a HO T5 is a High output linear fluorescent tube setup. I did some research and I also have a HO t5 setup, so I will be also speaking on experience.
Fiction HO T5's are less efficant than HID setups. This is not true. Here is a quote from Jorge Cervantes Jorge's RX in the latest high times
"Pay attention to the number of lumens produved. plants need lumens to grow. Your right a 250watt MH system is only 500 more lumens than your 200 watt HO t5 set up. Both lighting systems are very similar in lumen output,but the design of the t5 system makes it more efficient therefore more productive. The T5 fluorescent bulb delivers light along a long linear path, While a 250w MH system delivers light from a single point. Light diminishes to the square of the distance; in other words id fades fast. When light is delivered along a line rather than a single point it travels less distance to get to the plants. This makes the t5 inherently more efficient than the 250w MH lamp. Also the T5s run cooler than MH's so you can place them closer to the plants."

I am not going to argue with him!
Fact
T5's run cooler than HID. This is very true I have a 150 HPS and my 220w 6, 3 foot t5s are much cooler than that one bulb.
Fiction
You dont need to vent with T5s since they are so cool.
You always need to vent when indoor to get rid of the humid air. Yes T5 run cooler than HIDs but not "cool" they still get pretty warm and heat can build up in a enclosed space.
Fiction
T5 must be placed 2 inches away from plants.
Not true at all T5's are a High Output fluorescent. I found with my plant grew quickes when the t5's were 6 inches to a foot away.
Fact
T5's are expensive
This is true but the price in them is coming down a lot. watt for wat they are about equal to a HID setup.
Fiction
All Flourecents are the same and produce light fluffy buds
So very false! its in the name HIGH OUTPUT T5. They produce way more lumens than a reg CFL per watt.
I hope this helps anyone out. Like I said I have HO t5s and I love them! another pro is you can move individual tubes around your grow room to brighten up shady spots.
