Adding CO2 to the REZ?

[GuerrillaRed]

Here might be a dumb question... but would there be any benefits to adding co2 to the water in the res? I just got a Sodastream machine (I'm a Club Soda fanatic) which enables you to make your own soda pop by carbonating the water.

http://en.wikipedia.org/wiki/Sodastream

Since plants eat CO2 and produce O2 (in an extremely simplified explanation) I was wondering if I carbonate the water in the res would that help the plants uptake CO2 faster?

Anyway, just a random thought.

yeah that would probably work - roots need a co2 level around 5000ppm under ideal circumstances but you need to pay attention to your ph levels.

adding co2 dissolves in water acidic and will lower your pH

and use a so called flipper - to enhance the runway of the co2 bubbles

This is just plain bad advice my friend; roots need O2 ; leaves need co2 don't waste your time following such red herrings. A plain ol aquarium style air pump and an air diffuser/bubble stone in you rez is all you need.

Yeah roots need oxygen not co2.
and because of that, by adding co2 to the reservoir you'll probably be lowering disolved oxygen levels which is bad for plant growth and can also allow root pathogens to form. this is just a bad idea

Plants can only absorb co2 through their leaves so adding to the root zone is pointless

And sorry but where the hell did you get the figure "roots need a co2 level around 5000ppm"

That doesn't even make sense, I thought I read that in nature we have a co2 level of 300-500ppm and by using co2 enrichment in your grow room you can up it to around 1500 and anything over that may go to waste. 5000??? please quote your references, I am really interested to see where you got that number

LOL. WOW is all I have to say....5000ppm lol.

Listen to these guys - DO NOT add CO2 to roots...

Unless you want to kill your plants - in which case, go for it...

Good call guys - excellent advice...

This has been discussed a few times before and there are some silly "CO2 tablets" sold in hydro shops already.

a rough outline of a book called: ''plantfeeding''
it concentrates on the plant biochemistry ...

''The Co2-delivery doesnt only happen thru the atmospheric Air. An not to underestimate part comes from the Soil respiration - from the microbial decomposition. ... In Soil the CO2 level can reach up to 2% vol. thats a factor 100 higher than the atmospherical CO2 level. Concentrations between 3-5%, depending on the plants sensitivity, can harm the plant.''

this is a translation of a book part. also i know of a guy who regulates his ph with a Co2 pH Computer.

It's kind of frustrating that on some topics ppl just pass their self build knowledge which is plain wrong.

and also i was wrong - not 5000ppm but much 20,000ppm

Fact is that you need to stay within a certain PH range, so you can't pump hughe amounts of CO2 in your rez anyway.
Which kind of acid (carbonic-, nitric- or phorsporic acid) is most beneficial for your plants might be debateable, but i think the amount needed in a well balanced nutrient solution is low enough not to have a considerable effect.
I also thought of regulation ph with a co2 computer like it's done in aquariums when i built my system, but decided to do it manually for safety reasons. If there is a mayor PH change most likely something is wrong and with an automated system you might miss that until its too late.

exactly what i said!

Your out of you element donny..... Donny you're out of your element! Dude, the Chinaman is not the issue here!

I think you need a new book...plantfeeding?? wtf don't add co2 to your rez all you'll get is f-ed up pH and horse- shiz for yeilds...add air...we've tried adding straight O2 and the results were the same as the ones with the air stone...CO2 in the rez...
STFU Donny!

 

[Classy@Home]

Mr. Jones - I defer to your book.

Guys - Mr. Jones' book says to pump CO2 into your rez, so, plse pump CO2 into your rez.

Apparently roots uptake CO2, and this is the key to massive yields.

Well done, Mr. Jones - well done.

Any results should be posted in Mr. Jones profile, so he can revel in his knowledge.

first up you are a very sad person - second you can enhance your atmospheric CO2 levels by regulating your pH with CO2. if this is effective or not is not the question but it is possible. the fact that people used it for years with sucess should prove that ...

i bet it doesnt matter for the root system (if the pH is alright) if there is CO2 or not! if you reach 2% vol CO2 in your soil rockwool or what ever - respect.

and please stop quoting the big lebowsky - i love that movie and try to ignore what pathetic ppl watch it ...

edit:

roots dont take up CO2 - they dissociate it. im sorry if this led to confusion (i was confusing it too). anyways try to poison your plants with co2 in your nutrient solution - it wont work since they'll die before due to nutrient lack pH indused ...

im sorry for the troubles

Well at least you fessed up to your big mistake..but pathetic and sad...come on man the Big Lebowski is a classic Coen bros social metaphor and quite appropriate considering your senseless interjections in the conversation above...And I'm currently laughing, playing with my kids and designing a new 25 bucket e&g hydro system. Even your wishy washyconfession/ edit makes no sense...try dropping you ph to 3.5 and see if you plants die of "nutrient def" Dude...HM

well i just cant stand all this bashing everywhere - there is too much usuful information lost by treating a thread like this - am i wrong or doesnt lead a wrong pH to nutrient lock out - ive experienced it myself 4 weeks ago ...

have a good time with your kids! - i wrote an personal excuse as well

pH errors will cause nutrient lock-out which can lead to various micro and macro nutrient deficiencies...however a big swing in pH will cause SHOCK. Two weeks ago a kid we hired at the shop watered without pH adjustment which works out to about 3.8-4.2 normally. The only deficiency was a life deficiency ie dead plant the next morning.
