Best and cheapest CO2 systems

Hi everyone!
Growing indoors in a closet 5x5x6! No ventalation to speak of! Using 2 UFO 90 watt units. Using Pro-Mix What is the best and cheapest way of supplying CO2 ?? CO2 boost? or are thier better ways?
Thanx, Deedra

I haven't used it yet, but I read in Jorge Cervantes marijuana bible that a product called excellofizz works very well and it's a lot cheaper than the co2 boost. they sell it on amazon.com and I'm not really wanting to get a big co2 tank and regulator, so I'll probably give the excellofizz a try. all you do is add water to a disc and it releases co2.

The best way would be to use a co2 tank and regulator in that size room.
Or a water cooled co2 generator. But before going any farther I'd suggest you correct the ventilation issue unless your adding an A/C.

Yea dude just flowing fresh air gives them fresh co2 in the air.Don't starve your girls.
