Carbon dioxide levels can increase growth speed a great deal, it can even double it. The plant uses CO2 for photosynthesis to create sugars it uses to build plant tissues. CO2 level will increase the plants ability to manufacture these sugars and plant growth rate is enhanced considerably.
CO2 is most usable for flowering, but can be used during veg aswell.

The basic CO2 tank system looks like this:
20 lb tank $ 100
Fill up $ 15- 20
You can buy or lease cylinders from local welding supply houses. If asked, you can say you have an old mig welder at home and need to patch something up.
For a small closet, one tank could last 2 months, but it depends on how much is released, how often the room is vented, hours of light cycle, room leaks. This method may be overkill for your small closet.
It is good to have a small constant flow of CO2 over the plants at all times the lights are on, dispersing directly over the plants during the time exhaust fans are off. When the light is off you don't need CO2. When the fan is on for venting, CO2 should be shut off.
