I noticed on the youtube vids that the people who were doing the co2 bottles also had a 2nd bottle that had the bubble every so many secs , But they were being used for fish tanks or something

Since this is for my plants and not fish do i still need that 2nd bottle or can i just run my tube from my main bottle straight to the plants and not even have that 2nd bottle ?

Thanks in advance fellas

CO2 is heavier in concentration than regular "room" atmospheric air. It needs to be released slightly higher than its intended target plants. You can see the problem in dispersal immediately. Therefore treat it like water. Release it where it is needed or where it can follow a path to the canopy.

Uh oh, what about ventilation? I'll take ventilation with good total room air exchange every 5-10 minutes and heat control over supplemental CO2. In small grows I am saying right now CO2 is a luxury and far from a proven necessity. The CO2 (which is NOT cheap!) will exit the room as quickly as the rest of the air.

Now, as a positive side to global warming (maybe the only one) is the increase in CO2 in atmospheric air. Due to people, internal combustion engines, melting of permafrost in the Arctic (HUGE releases here). In short - screw CO2. Focus on ventilation and cooling. Control and provide those and the plants will reward you more than with CO2.

Saying this as a welder who grew up in a welding shop. That drove me into medicine but I still weld. TIG/MIG/DC. LOTS of CO2 around and trust me, I've used it. Lug those damned huge "K" cylinders to the gas company for refill. Load it, rolls allover your truck bed smashing stuff. Break your back and buddy THE PAYOFF IS NEGLIGIBLE! Buy a bag or two of ExHale and hang them over your grow. Good luck.

Temps and all under control my man

If you think i dont need the co2 line then i will take that shit out ( stinks lol )

Here is a quick vid of how i have my closet just to give you an idea of what im trying to work with

You will notice some discoloring on some leaves , my ph pen was out of whack and i did not know it so when i adjusted my ph to 6.4 i was really adjusting it to around 3.9 ( whoops i know )

But i have it calibrated now and their starting to recover

hotrod, ever heard of a co2 generator? no lugging bulky tanks, investment in equipment paid off in first harvest, and monthly running cost is about $8.

After all the reading Ive done on CO2 I think your information is misleading. Normal PPM for CO2 in the air is 300-400. For flowering you should have it around 1500 ppm which is 4-5 times the normal amount which = significant yield increase. I'll be running CO2 for the first time this grow but everything I read from people who use it correctly is that it's totally worth it. Its only 14$ to fill a 20LB CO2 bottle and usually takes 2 bottles for a grow so not sure why you say its expensive. The equipment and start up cost might be pricey($600 for me) but thats pennies in the long run. I agree it is not a necessity but to say the payoff is negligible seems pretty far fetched to me.
