C02 tablets

[Glassy80]

There are some C02 tablets on eBay - <!-- m -->http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... :IT&ih=015<!-- m -->

As far as I understood, the CO2 is taken in by the leaves and not the roots so im not sure how these would work. I'm trying to find a cheap source of CO2 for my plants while they are in veg. Anyone recommend anything, as I can't see how these tablets would work.

put it in water and the gas that comes out after it desolves wil be taken in by your plant!

are those or any other co2 tablets worth it? thinking about getting them and where can you get them, do they sell them at hydro stores

I found exofizz tablets (or something like that) for $8 each. Not very cost efective. Last for 5 hours or so. So it's $8 a day.

I got a co2boost bucket and am trying it out now. I was way too impulsive. Iv'e read since I bought it they aren't worth it. Live and learn.

Note to self." use the search button before you purchase"

Anyone ever play with that as a kid? It produces copious amounts of C02.

Talk to your plants & get a 2 ltr bottle, fill the bottom 2 inches with vinegar, toss about a tsp of baking soda in there and viola! c02. Less than shipping, easier to use. It will only produce about 5 minutes of c02, but it is a concentrated dose. Practice before you put it in your grow spot...so it doesn't spill all over.

Side effect, it'll also help mask the smell a little.

hi!! - i also want to try the tablets thay sell at the petshop with aquariums --- ive heard that MJ can absorb CO2 by roots---- do u know what level of CO2 is good for MJ? peace

[seedling4life]

I read that they only use CO2 when the lights are on, can someone confirm?

Very true

[5TURBO]

surely this is more trouble then its worth, plenty of fresh air is good enough for the plants!!

That was my first thought...that or a crapload of alkaseltzer.

Role in photosynthesis

Plants remove carbon dioxide from the atmosphere by photosynthesis, also called carbon assimilation, which uses light energy to produce organic plant materials by combining carbon dioxide and water. Free oxygen is released as gas from the decomposition of water molecules, while the hydrogen is split into its protons and electrons and used to generate chemical energy via photophosphorylation. This energy is required for the fixation of carbon dioxide in the Calvin cycle to form sugars. These sugars can then be used for growth within the plant through respiration.
Even when vented, carbon dioxide must be introduced into greenhouses to maintain plant growth, as the concentration of carbon dioxide can fall during daylight hours to as low as 200 ppm (a limit of C3 carbon fixation photosynthesis<sup class="noprint Template-Fact">[citation needed]</sup>). A similar event on a global scale occurred after the Permian period, when Earth life almost became extinct. A repeat of such conditions (a decrease of carbon dioxide concentration to about 60-65% of its current level) would kill 99% of existing plants and undoubtedly eliminate human civilization (carbon dioxide deficit was also the most likely reason for most big life "extinctions" on the planet)<sup class="noprint Template-Fact">[citation needed]</sup>. Plants can potentially grow up to 50 percent faster in concentrations of 1,000 ppm CO₂ when compared with ambient conditions.<sup id="_ref-16" class="reference">[23]</sup>
Plants also emit CO₂ during respiration, so it is only during growth stages that plants are net absorbers. For example a growing forest will absorb many tons of CO₂ each year, however a mature forest will produce as much CO₂ from respiration and decomposition of dead specimens (e.g. fallen branches) as used in biosynthesis in growing plants.<sup id="_ref-17" class="reference">[24]</sup> Regardless of this, mature forests are still valuable carbon sinks, helping maintain balance in the Earth's atmosphere. Additionally, and crucially to life on earth, phytoplankton photosynthesis absorbs dissolved CO₂ in the upper ocean and thereby promotes the absorption of CO₂ from the atmosphere.<sup id="_ref-18" class="reference">[25]</sup>

so basically only use it during the veg stage when the lights are on? just trying to make sure i understand that passage...

[OldSkool1010]

That's the way I interpreted that article in wikipedia too; plants absorb CO2 during the daytime (lights on) and convert the carbon into sugars during the dark period...but MJ works a little different from what i understand. MJ does not need a dark period to metabolize the carbon, seems like MJ can do it all during the daytime

[weedman040]

awesome... thanks.

I too bought and used a c02 bucket and didn't see much difference. I read a good article recently about grape vines...... the jist of it was that with natural c02 levels increasing plants now a days are being exposed to much more c02 than they were just 50 yrs ago. (fresh air at all times basically is what is needed)

I'm convinced that unless you have a completely sealed room with c02 tanks and awesome ventilation on timers so as not to suck out all the c02 you are trying to put into the room then forget c02.

I'm also convinced the grow advertisers are no different than diet pill advertisers. Half the stuff out there is bullshit. Excercise and diet is the only real way to lose weight. Diet and excercise = fresh air and decent nutes. IMHO of course.
