Just How Important is CO2?

[GStoke8]

Im about to get my first grow up and going. Plan on growing three bagseed plants in a fairly small closet. I have the seeds germinating right now, but heres my question (or one of them for now atleast).

I know CO2 is like what oxygen is to us for the plant... so i know its important, but how important? Will i still need some type of co2 setup or will it be ok without one?

Oh and one more quick question. Any recommendations of soil i should use that i can get at a walmart or lowes or somewhere of that kind?

Fortunately there is CO2 in fresh air. If you can rig up something that moves new air into your room, and expells the old air out, you will be bringing more CO2 across your plants than normal. In a closet you can cut a hole in the roof and put an extractor fan in there. Expelling air will cause more air to come in over the doors and through air gaps to replenish the expelled air in the closet.

If it is possible to make an intake hole in your closet, make it at the bottom of the closet to bring in the cool air near the floor.

Preferably though you are bringing in new air from outside the house, like, from under the house, but any new air is better than none, so if you cannot bring in air from outside the house, at least bring in new air from outside the closet.

The extractor fan and the venturii effect will sort the rest, but it helps to add an oscillating fan too.

well some say Co2 is in fresh air...well oxygen is in water too...Go try to breath in water and tell me if the fresh air in water is enough for you?

so do you think fresh air enough your plants regarding Co2. Hmmm?

Get a Co2 supplement it is that important.

If your going out and getting things for a new grow op, get something better then bagseed , do it right and get some seeds fram a seed bank, and Co2 is quite important.

Co2 benifits:
Vegatative: Can take up to 14 days off the plants life cycle, helps plant growth during veg.

Flower: (I hear many percentages but) Can increase yield by 20-35% (possibly more!!)

There is Co2 setups you can buy,

When you buy a Co2 setup like that your still gonna need a Co2 bottle. You can get some decent ones off ebay, I got mine free though . A 20lb tank will last for 6 months in my closet (not too bad!!) depending where you live you can either get them refilled ($20) in my area or they do swap-outs.

Or theres some threads on here how to make home made Co2 using water,yeast and sugar.

as cheap and easy as that homemade co2 rig seems i think ill try that route out. thanks for the link jeffdog thanks for the help so far guys

NP and good luck buddy

Basically , plants dont need air to breathe, they need C02. If u dnt have a co2 tank, using fresh air is just getting fresh c02 to the plant. the oxygen doesnt matter, its the co2 they are after.

didnt really read any ones posts, so if this was mentioned, my bad.

i think adding extra co2 is something that at worst won't do anything but possibly hurt your plants and waste your money and at best will give you a few percent on your final yield in a commercial large scale grow op.

why does everyone wanna use co2. don't look for shortcuts. time experience and proper soil, lighting and environmental conditions are what make big yields.

and to above poster, plants use O2 as well!! just not as much and predominantly during periods of dark.

According to some accounts, the rise in carbon dioxide will usher in a new golden age where food production will be higher than ever before and most plants and animals will thrive as never before. If it sounds too good to be true, that's because it is.
CO2 is the source of the carbon that plants turn into organic compounds, and it is well established that higher CO2 levels can have a fertilising effect on many plants, boosting growth by as much as a third.
However, some plants already have mechanisms for concentrating CO2 in their tissues, known as C4 photosynthesis, so higher CO2 will not boost the growth of C4 plants.
Where water is a limiting factor, all plants could benefit. Plants lose water through the pores in leaves that let CO2 enter. Higher CO2 levels mean they do not need to open these pores as much, reducing water loss.
However, it is extremely difficult to generalise about the overall impact of the fertilisation effect on plant growth. Numerous groups around the world have been conducting experiments in which plots of land are supplied with enhanced CO2, while comparable nearby plots remain at normal levels.
These experiments suggest that higher CO2 levels could boost the yields of non-C4 crops by around 13 per cent.


However, while experiments on natural ecosystems have also found initial elevations in the rate of plant growth, these have tended to level off within a few years. In most cases this has been found to be the result of some other limiting factor, such as the availability of nitrogen or water.
The regional climate changes that higher CO2 will bring, and their effect on these limiting factors on plant growth, such as water, also have to be taken into account. These indirect effects are likely to have a much larger impact than CO2 fertilisation.

i totally disagree with ur post... why do u think we have oxygen here on earth? plants , trees, etc, take carbon dioxide and convert it into oxygen, please dont post if u dont know what your talking about.
Thats like grade 2 science.
If we had no green life here on earth, we wouldnt have oxygen to breathe.

theres truth in both your statements. your plants roots need oxygen and its leaves need CO2.

and ive grown in my room with and without CO2 enrichment. CO2 enrichment definetly will increase your growth rates and yield, but you really have to know what your doing for it to really be effective. and as long as you have fresh intake air your plants will be just fine.
