Co2 balancing

Ok ive used that calculator,and it just doesnt help. Ive a 2.4x1.2x2 tent.ive my fresh air supply,the light are on their own circut,and ive a 10" fan on speed control with a 10" carbon filter,so my question is,how do you juggle the heat the smell and optimum co2 levels,if it gets to smelly the fan will have to go on(extracting the co2),and the same if it gets to hot,but the heat shouldnt matter to much since they have thier own circut,so im left with this dilema,what to turn on when and how long to leave the co2 before extracting an then replenishing?????

I've been wondering this as well

yah me too

in a confined space like that, don't even bother with co2. fresh air will do you just fine. imo, a 10" fan is too much for your space. to get the optimal response from your plants using co2, you have to have total control of your environment. your space is pretty small, and fresh air will do you just fine. it takes a lot of equipment/money to properly utilize co2.

Ive got the money,and the equipment,just need to know fan scheduals,ive speed controld for the fans,so ive just to slow it down

either way,wether to use it or not,how do we use it?what schedules??

here's something i found and a good link.

Carbon Dioxide Systems

Researchers have been showing that an increased level of carbon dioxide can improve the growth, quality and yield of crops as long as the plants have adequate light, nutrients and water. Many hydroponics and greenhouse growers have been incorporating CO2 generators or emitters and CO2 monitoring controls into their growing environments. To achieve ideal results, though, certain conditions need to be met. Ideally, the indoor garden area or greenhouse needs to reach 1000 ppm (parts per minute) CO2 within 10 minutes. This allows the greenhouse to achieve ideal CO2 levels after exhausting or venting the area hourly.

Venting or exhausting the area should occur just before enriching the room with CO2. The Green Air model CT-DH-4P can coordinate cooling with the CO2 generator (such as model CD-12) so your system will vent the room and then generate the CO2 needed. The photosensor on the CT-DH-4P ensures your system will not generate CO2 at night while the plants are resting. The simplest and least expensive way to monitor CO2 levels is with Green Air Product’s new Set Point Controller (SPC-1). The SPC-1 samples the air and maintains the desired CO2 levels.

Sounds like you need to Google a CO2 calculator. It will tell you how long you need to run CO2 in your sized space to achieve the optimal 1500ppm. Then you will know when your fans, AC, and other stuff should run. Obviously you won't want your exhaust on when you're pumping in CO2 as it is counter productive. If you still can't get it figured out just put your CO2 on a 15 on per hour timer. I would think that 15 minutes wouldn't be long enough that your grow would overheat or produce an extreme amount of smell. In fact having higher temps with CO2 on is a preferred so it might just all work out!
