co2 options

I will be using co2 in a closet type space with atleast 10 plants and wanted to see if the less expensive options are worth it. I have seen co2 boost and another product that comes in a bucket and you submerge some kind of "puck" in water to make co2. It say it will raise co2 levels to 1600 ppm. But if a co2 tank system is the only way to go, I want to do this right.

i have never tried co2 boost.. but i know people who have and they say it is great....

i saw their plants... they were not great... LOL... if you want to do it RIGHT... i say, go with a burner

you can see one in this video.... How to grow marijuana - See More Buds - DVD Video trailer

I have heard of the co2 buckets never used them but personally I use co2 injection tanks.A 20 lb tank with a solenoid and timer and do timed injections. Burner work great but you need bigger areas and they add heat which can be an issue.for under $300 you can have a nice littl injection system maybe even under 200 if you shop a bit used.
