What? they're Bad with Co2?
Because you can't isolate the light/heat with an air-cooled hood or cooltube, which means you need to have your ventilation system running more often, which will suck out the co2 along with the heat, defeating the purpose. Well, I guess theoretically you *could* build one huge honking 'cooltube' for that T5 system, but it'd be enormous, and way difficult.
Hi guys...Im glad to see that everyone has taken a liking to this thread...I am using the grow T5 not the aquarium t5...better reflection... I can see why everyone thinks these plants arent for real...the growth from this light is incredible I do admit!! For that aexact reason is why I satrted this thread...Believe me I would tell my buddy everyday that his new light sucked and that my HPS were gonna be a better yield...we ended getting about the same yield and in my opinion his plants looked a lo nicer...So I am posting my grow step by step so that all can see...
My plants are forming a hedge which is pretty hard to be penetrated by light...We chopped a ton of leaves yesterday to open the plants up a bit...Im sure they will filll in nice...Im not to worried about the bottow dwellers anyway...I will be putting mylar on the walls next grow...Im sure that will help a little!
Im not to sure on the CO2 thing....these light dont emit that much heat where the extraction fan is on all day..im sure I could turn the fans off while running co2...
To all the thread readers...feel free to put me to the test...I will answer any question or doubt you might have about these plants!!
Pass me the lighter my Dear Watson!!:pimp:

I think you'd find those lights put out a lot more heat than you think they do. They seem cool(er) because the heat is generated over a much larger area, whereas with HID lights it comes from a very small area. They might even generate MORE heat than an HID, I don't know. They use more power (compared to a 400-watt HID light), and generate less light, so that reduced efficiency and extra power usage is being turned into *something*. If it's not light, and it's not matter, then what else could it be but heat?
I bet if you sealed up your box tight, and turned off all ventilation, and turned on the light, and did the same thing with a 400-watt HPS light, and used the same starting temperature in both scenarios, that after an hour of the lights being on, the temperature in the box would be comparable. If it's not, then either the laws of physics are being violated, or that energy usage is being turned into something other than light or heat...and I don't know what that could be. If it's matter, then the lights would gain mass over time, and I don't think that happens. Sooo....
That sounds deep and Im stoned...sounds like your right though...Id like to test that...
Do not get confused mate here. Do not compare the efficiency of 2 different systems by subtracting their wattage difference to heat. Other reactions needs to be done in actual-physical level on each lamp type. The energy is used in totally different principles, so any attempt to compare is by definition wrong. Not only light, heat and matter can be present on the equation, as you say.Quote:

-HPS produces more heat, more lumens and dirty light.
-T5HO produces less heat, less lumens (yet) and quality light.
you go boy!!Quote:

i think they look a little droopy due to the fact that we cut back a lot of leaves last night...kinda shocked a little bit...but they are bouncing back!!
