If you're trying to use carbonated water for CO2 enhancement keep in mind that you are literally better off taking a big breath blowing on the plants (lungs have a vital capacity of about 4 liters and our exhale is about 45,000 ppm CO2).How old does a plant need to be before foliar sparying with Co2 water?
Any elevated levels of CO2 will increase the rate of photosynthesis in a linear manner until saturation levels are hit. 1500 ppm or so is about where you want to be for maximum efficiency but any additional free CO2 in the air can be taken in by the plants.co2 ppm needs to be up around 1500 before it has any bennefit
You don't need to keep the plant moist like this. In fact, doing so could encourage a fungus outbreak. You're right, with good airflow you don't need CO2 enhancement.i am curious about this as well and noone has directly answered this. blowing would be better theoretically. but since i also want to keep moisture on the plant and provide co2 over a length of time, spraying with carbonated water seems to make sense for me. My plants are 4 weeks old and roughly 4 inches tall, i wasnt planning on using it until at least at 1 foot tall because there should be plenty of co2 everywhere. In fact chemically with an air flow system (a fan even) i dont see why you would ever need co2 unless you sealed the room off
lol, you can see my post somewhere in this same newbie forum, the reason is i used a 75 watt plant flood light during the 4 week period, its bagseed and was experimentalYou don't need to keep the plant moist like this.

Now, descibe how you're growing so we can figure out why your plants are only 4 inches tall at 4 weeks.
Even starting with a 75 watt plant light many years ago, I don't think I ever had a 4 inch plant at 4 weeks. If anything these plant lights will cause excess elongation. It's not the light, you're doing something else very wrong.lol, you can see my post somewhere in this same newbie forum, the reason is i used a 75 watt plant flood light during the 4 week period, its bagseed and was experimental
now that they are growing in the grow room (and having better seeds on the way) with 2, 40 watt cfls and a 250 watt hps they should get some life back and be ready for my next batch
