So from the research i've done, Led run cooler than hps but there not totally cool they heat up the rooms ambient temperature, extractor fans are used less because of less heat, so not getting the co2 from good extraction, although its recommended to use a heater with leds under the right circumstances.. So would it be better to run a sealed room with a co2 gen, to create the perfect enviroment?.

Not getting CO2 isn't a by product of extraction as much as it is a lack of intake air. To answer your question, yes a 100% sealed room with the correct environmental controls with CO2 generation controlled air intake and exhaust, controlled temp and humidity, etc etc will give you a controlled environment to test and complete a grow with you having the ability to control everything. If you are not very experienced in growing this is not a good idea. there are a lot of factors that can easily be mismanaged.

a sealed room does not need, and should not have, and intake or exhaust except for a sealed loop for aircooling the lights.

Sealed doesn't mean that no external air ever gets in. It means that you control when it gets is. Without a gas burning unit inside the tent you will create a very oxygen rich environment that can become dangerous. Likewise, you need to cycle the air that is inside the tent to refresh it. A 100% sealed room with no means of exchange will kill your plants. This is very easy to test on a small scale, place a nice healthy new clone in a zipploc bag and leave it for a week. It will die without fresh air.

bullshit. i call bullshit. i just harvested my 1000th plant from one of the most sealed rooms you will see. cycle the air? bullshit. the only time the is air exchange is when i open my door to go in or out. 6'x10' room, osb, 24 tubes of caulk, 5 coats of rubber paint, no entrances or exits in room except for ac and water lines and they are sealed. i call bullshit. the cutting in a plastic bag thing is not even close to a comparison. i pull 40+oz from my sealed room every three weeks, how dead are those plants?

well you cant just put up drywall,studs,osb, and insulation and not have access. please tell us your idea of a sealed room, using velcro zippers?

What myself and guod are referring to (correct me if I am wrong) is a clean room type environment. A sealed pre-entry room that the air is removed from prior to entering the grow/clean room. The number of times per day that you open/access your grow area MAY be sufficient to exchange the air. You may have leaks elsewhere in your room or through the walls or door seals. If it is actually sealed, the air exchange from the plants will increase the oxygen in your room to the point that a spark will cause an explosion or flash fire in other items within the room readily. This can happen at oxygen contents as low as 25% (normal air is roughly 21% depending on factors like MSL, RH, etc). Running a gas burning CO2 generator on a timer rather than short intervals can make the likelihood of explosion much higher.

we are talking basic growing here guys. you can make a case about anything if you want, but stick to what is helpful for growers. for a room to reach that level of o2 saturation is almost unheard of as a grow room unless you are releasing bottled o2 into the room

its the only way to go indoors. plus i dont have to use carbon filters, no odor escapes.
