Indoor Co2 FOR AUTO FLOWERS ? whats your thoughts ?

[lou9571]

I would like to know everyone's thoughts on adding Co2 to my set up ?

I have a 3 sq feet stealth dresser and a 100w blackstar led light ?

co2 is used best is closed loop systems where the hood is vented.

If it was me, i wouldn't bother. The results wouldn't be that noticeable in a smaller cab. imo.

I use Co2 in my stealth box and it seems to really help in the veg stage with getting them going good. I shut down my exhaust fans for 20 min to let the cablinet get hotter and inject Co2 at 3/4 bubble for 10 min while the exhaust fans are still off. Co2 is absorbed better at higher temps is what I shut them down. THey dont come back on until the Co2 has stopped flowing for 10 more min so I have about 30 min of off time on the fans but with a LED I can do that as it doesnt get that hot anyway. I run this sequence 4 times a day currently. You will not want to run Co2 in the last few weeks of flower as it can decrease yield or potency from what I have read.

Also Co2 is best when vegging & not as needed in flowering. Like TBM said fresh air is good enough.

co2 is the shit even in flowering!!!!!!!!!!! outdoor air ppm is 300-400 you can run 1500 ppm in your grow so that means you can run the room at a higher temp your plants will take in more nutrients and they will grow 40% more and yield fat hard nugs but ppm needs to stay at a steady 1500 ppm all day till lights out so you would need a digital co2 monitor to tell the regulator to turn on and off when i hits 1500ppm but it not cheap over 400 us $

no get as much fresh air as you can not from the room from the window use dryer vent

if you really want to use co2then you could always get carbinated water an spray it on your ladies down b4 they go to bed and make sure you spray under the leaves too lol i know this works well in in city where you dont want to flood the room or space with too much co2, but dont spray the last month due to wet bud = mold meldew and other stuff u dont want

 

[BLUNTMAN123]

spraying the plants beforlights out i dont think will do any thing plants dont take in co2 when lights out

 

[dirtybongwater]

i dont know about that im just going on what ive read and what ive seen on youtube but if thats the case then spray them down when they get up lol

thank you alll for you thoughts ! what i was thinking about doing what setting up timers so when the co2 was on my fans where off what do you guys think about this ?

Do you think it would be money better spent with me buying the 240 w blackstar led and putting that in there ?
