co2 question . (carbonated water)

ok , so Im watering my babies with nutes atm ..
would making a nute/carbonated water solution be a good idea or no ?

I couldnt make much because it would go flat if it wasnt air tight . but you get the idea .


advice ? input ?

Your roots don't need it, your leaves do. Use a spray bottle with bubbly water and have fun... Just don't get any water on your lights.

I have 2 liter bottles filled with yeast and sugar to produce co2 and they are hanging in small macrames my wife made for them.

The plants use CO2 during their day cycle primarily and use the stoma as a means to absorb it. So in order to efficiently use CO2 on your plants you must make sure that the humidity is not too high and also that the plant is not to warm. In order for the plant to acquire the CO2 it will have to open it's stoma and release some water while bringing in Air(H N O2 CO2 ect.) The gas exchange is a very important process for any plant and if it is too warm for the plant it's stoma will constantly be open as a means of transpiration which will cool the plant down but not be focusing on gas exchange. Also if it is too cold the stoma will not open so for those who want to kill chlorophyl late in the cycle to turn your bud purple or blue or deep violet or even yellow in some cases, timing is everything. Eitherway I do not mean to drift off topic here but I say no to carbonated water and Yes to yeast/sugar pool nearby or whatever your little heart desires.

Dry Ice sells for about 1$ a pound and is just straight up frozen compressed CO2 and you can buy that at wal-mart as far as I know. Be careful with Dry Ice though, don't handle it with your skin.
CO2 canister.... whatever is in your budget i suppose. Jumping on an excersise bike near your plants would do it to be honest... I don't think i could spin next to a grow lamp though, F THAT.

Oh I almost forgot to mention a these things, MJ is a dicotyledon and the majority of the stoma on this plant will be located on the underside of the leaves, you can see them on large leaves and smaller ones you will need magnafication. You might be thinking So what? Well CO2 Is heavier than oxygen nitrogen and hydrogen so it's going to naturally sink to your floor if you do not have proper venting and air movement. The brownian principal will cause some CO2 to make it to the plant no mater what your air movement is like however a good flow will help very much. Not necessarily room to room air exchange, but moving air, any fan could assist in this case. Also make for damn sure you do not get carried away in producing CO2, it is poisonous once you get up and over 50,000ppm it's directly toxic and deadly to us, LUCKILY your plants will THRIVE in 1300-1500 PPM of Co2. Around 20,000 PPM you will huff and puff like the big bad wolf and probably feel like passing out, just make sure if you are messing around with co2 and your heart starts pounding for no reason or you start breathing heavier than normal, just get out, take a good breather outside and then figure out how to get some better ventilation.

thats strange I actually read it in a book .
so ill probably try it no offense to anyone .
thank you very much for your info .
but 1 plant isnt going to make/break me anyways =p .

Don't do it.
While leaves consume CO2 and excrete O2, roots are the exact opposite. Using carbonated water (CO2 infused) will release a large amount of CO2 in the root zone and displace the O2 the roots need to survive.
For example, injecting oxygen in the root zone is the whole point of air pumps in DWC. If the air pumps or agitation/waterfall devices fail, the plant can quickly die. The water is usually chilled because cold water can hold more dissolved O2.
Again, DON'T DO IT! Once may not show any ill effects. repeated use will definitely slow growth and eventually kill the plant.

^ very good . never thought about the comparison between the co2 vs o2 provided by hydroponic .
valid point indeed .
