Well, my grow room averages 75F to 85F, sometimes as high as 90F. Again, not trying to be a jerk, but you are wrong about your assumption of CO2. CO2 does not NEED higher temps, but it ALLOWS you to have higher temps with no worries. I know what the CO2 does for my system based on experience. CO2 has given me larger, almost double in size, buds, and quicker turn around times.
Good point but perhaps he does have his temps up around 85. Least hope he does, if not like you said, waste of CO2. And with fluorescents its kinda a waste anyways. Limited lumens produce limited plant metabolism. Probaly dont need the extra CO2 too begin with........
Cool, I just didn't want you to think I am coming off like an Ahole.
Is that why you only have 1 inch of good buds?
No no, you actually need higher temps to use CO2, it causes the plant to transpire faster, thus taking in CO2 and releasing O2 quicker. How can your grow room get as high as 90 with T5's? Sounds like you'd be better off just using HPS.
It does need higher temps dude. More rapid exchange of gas.
Does it really matter in a sealed room? Its in the air because there is limited floor space.
If you have a dense canopy and are only circulating air above the canopy I would have a few computer fans blowing up through the canopy from near the floor to keep things evenly saturated.
Prove it...I think your a bit more basis towards CFLs and T5s from the sounds of it. Any pic I've ever seen of T5 weed vs. HPS weed has shown radically different products in both appearances, colors, and THC crystal density. Like I said I have nothing against T-5s they produce some dank weed, but its not as dank as an HPS. I'm not trying to say HID is better than CFL or T-5s. They both have their place in the sun. And each one is better for xyz application.Not trying to be a jerk, but those are wrong statements, very wrong.

This statement is 100% correct. You don't need higher temps for Co2 to be effective. What higher temps do is just make the plant use up CO2 at a faster rate (it also lets the plant tolerate higher temps). Since most people fill up their rooms once every hour to every 3 hours you'd just burn through the Co2 faster at a higher temp (I'm assuming the theoretical grower isn't using a overpriced controller). It's this reason that CO2 levels drop in warmer areas and raise in cooler areas (when plants are bloomed). In the winter most plants are dead or in "slumber" so obviously Co2 will rise then.
Exactly, but I guess Herrekin just wants to be a smart ass. I actually have my CO2 tubbing run all throughout my chamber because it is sealed and circulated.
Exactly, I do have fans all throughout the grow. Fans blowing up through the canopy, and fans pulling air to the top chamber, and fans pulling it back down to the bottom through tubbing. The temps and CO2 are completely equalized between the chambers. I don't have a controller, so I had to do my own testing with manual co2 testers, testing both the top and bottom chambers. Same with temps, I have monitors throughout.
See above.
Right on bro, that's all I'm trying to say. Each growing method is different. For me, being small time, T5's work great with scrog or sog. If you want to grow 4 or 5 ft tall plants, cfl's/T5 is not a good option.
Mainly because I am working with a stealth sealed cabinet. I don't want any noise or any fans and tubbing coming out of the chamber. Everything I have is completely sealed inside, thus the ultimate stealth.
I hear you on that. In any case, yes for smaller plants T-5s work great. So do HID's. In fact I'd never grow any plant with a 1-2.5 feet in finishing hight in doors. HIDs and T-5s alike suck at growing larger plants. Nothing beats out the sun in terms of light penetration. Even a 1000w HPS won't penetrate that far when plants get bushy and over 3 feet. I like you like a lot of smaller plants over a few larger plants. I'm doing a 2000w SOG setup when I move out west this spring/late winter. Everything is purchased, I'd just rather live somewhere where I can do my thing legally. I'm a firm believer it's never a good idea to break any laws (even if they suck). Too much is at stake.Right on bro, that's all I'm trying to say. Each growing method is different. For me, being small time, T5's work great with scrog or sog.

I'm not biased towards T5's, I've grown with HPS also, I just found that fluro works best for my situation.
And as for the "prove it" part...I'm not comfortable posting pictures online. And for anyone that would say I am just BSing, so be it. I have been busted before, and I'm not looking to try that again. It took me 5 years before I even went on a forum again, but I've been around since before the OG days... I promise you my bud is not airy, or less potent. They are dense, and my friends (some of which don't even know where the bud comes from) say it's the best they've ever smoked.

Yeah, it's a bit small scale, but that's me lol. I have 2 105w CFL's with 6200 lumens each, and 4 T5's with 2000 lumens each in my flower chamber. I have 2 85w CFL's with 4200 lumens each in the mama chamber. My seed, seedling, and clone section is divided into 3 sections, seed chamber has no light, middle section for seedlings after they have reached the surface has (3) 1 ft T5's with 350 lumens each. Bottom chamber for clones has 4 of the same 1 ft T5's. If you keep them 1 or 2" above the plants, you get no stretch and they thrive like crazy.
