to CO2 or not CO2 that is the question

I have read, and I think understand the fundamentals behind CO2, but how to generate, remains a question. In a small, stealth indoor environment, I have read a couple of innovative solutions to this....has anyone tried and had success? what about Alkaseltzer in a glass?

Silver Nomad has written an excellent post on this exact subject. very detailed and much better than one I myself subsequently wrote without realising that he'd already written one. There's a good one with some pic's written by a geezer called H20xygen also. If you've got some readies though, it's far better to buy the cannisters from the shop. Not sure if a plant has a maximum on the stuff, but if their air is rich with this stuff your plants will reward you well.

In a small area the C02 produced by the plants is enough...altho the more u add the better...i´ve read something about a home made C02 generator in this forum never used it but it sounds right so use search and look 4 it...Peace and Pot

i remember my 5th grade earth science teacher saying that plants breath CO2 and emit O2, not CO2....

U should have gone a bit further then the 5th grade bro ... Plants do not breathe in the same way as animals and humans do. Plants' breathing is passive, meaning that they do not need lungs to push and pull air in and out. During the day, plants photosynthesize using the sun's energy, water, and CO2 from the air to make oxygen and sugars. The oxygen is released from plants' leaves during the day. At night, they use a little oxygen and release CO2 in the air. This is called respiring.This is why some growers bealive that plants only use up to 18 hours of light per day, during the remaining six hours it is belived that plants close their Stomatas in orther to realease C02.

Omega, maybe you can clarify this for me. If the plant itself breathes in Co2 and the roots O2, won't then each support the other? The roots breathing in O2= generated Co2 for the plants, and the plant breathing in Co2= generated O2 for the roots?

thanks for all the notes and comments. In the mean time I have found out that elevated levels to 1500-1800ppm can still remain beneficial (normal atmosphere ~500ppm). In a small grow cabinet, I expect that a simple passive release system will probably suffice.

Yes, its like a symbiotic relation, the same way that plants growth is oriented to light ([SIZE=-1]Photomorphogenesis), the roots also grow according to an orientation that can be induced by gravity ([/SIZE]Gravitropism) or by oxygen (oxytropism).Oxytropism allows roots to avoid oxygen-deprived soil strata and may also be the basis of an auto-avoidance mechanism, decreasing the competition between roots for water and nutrients as well as oxygen.By doing this the roots are providing ideal conditions for the plant to develope at full potencial...that is why hydroponic systems promote faster and bigger growth ratios (in normal circunstances) then soil, the roots[SIZE=-1] are more exposed to Oxygen (and nutrients) therefore the symbiotic relation between roots and the rest of the plant is done at a much faster rate...In Aeroponics this symbiosis is taken even further by exposing the plants roots even more to Oxygen leaving only the roots tips in contact with water altho the entire root structure is constantly mist with water and nutrients, the capillary action is more effective due to more Oxygen available....

i made one out of a gallon jug of water cup or2 of sugar ans a teaspoon of yeast and piped it around the plants with straws. Works great

Nevermind saw a setup w/ straws, or aquarium tubes, pretty smart idea, I'll definately give this a try.
