Soda Stream soda water in the nutrient tank?

[Brimstond]

I was just making a sodawater and was just wondering what would happen if I used some in the nutrient tank?

Does anyone know the pros and cons ?

Would it release CO2 into the grow room , would it add oxygen to the water, would it kill the plants ?

 

What you rekon?

co2.. or carbonated water wouldnt really be all that viable in the nute tank... i couldnt see it doing any harm... and most probably would do some good.. especially for the root system.. how ever its an expensive exercise when you consider the bubbles of Co2 would only last a couple of hours at the most... the easiest and most cost effective way to keep your nute tank oxygenated would be to just use an airstone and air pump.. a constant stream of air bubbles.. like a fish tank..

 

using soda water on clones as they turn their first signs of roots maybe beneficial.. although i would still think using it as a foliar spray would be more beneficial.. by foliar feeding the plants with Co2, the water holds the Co2 to the leaves and is easier for the plant to take it in..

 

try adding a little wormjuice to the soda water as a foliar spray.. it seems to work for me... not too much.. a ppm@3-400 is perfect... if you dont have any wormjuice, you could use a little of the resi water... not too much as it may burn new foliage just a little.. 1/4 strenth.. so around the 3-400ppm mark...

i would say use it in the grow room but not in the tanks

Plants absorb CO2 from the air via their leaves and oxygen through the root system, CO2 is not something that I would add to the nutrient tank, try Oxy Plus or similar if you feel that an air stone or 2 can't do the job.

Tom's quite right, adding CO2 to water or nute tanks is a waste of time as roots want O2, not CO2.

 

I use 50% grade H2O2 (one brand name is Oxy Plus) at 1ml/litre of tank volume every 3-4 days, but that's for pathogen control, not primarily for root oxygenation, though it does have that effect when the H2O2 breaks down. I run a bubble curtain in each tank for root oxygenation.

A fellow on another board is playing around with introducing CO2 to the roots. He's found some anecdotal and some old (1961) research on the topic. The anecdotal (one plant under test, one control) seems to indicate that plants with roots exposed to CO2 develop smaller leaves but still gain more plant material mass than non-treated plant. Jury's out on whether this means more total plant mass or if indeed it's a bad thing, causing smaller leaf and thus bud formation.
