I've messed with co2 a little, but have a grow bro that uses it extensively...we have been wondering about this 02 during dark, but keep in mind an o2 charged atmosphere is VERY dangerous...things that wouldn't normally burn, will burn very quickly in an o2 enriched environment! Be safe about it!!!
Yes plants use more o2 during dark cycle. No not injecting straight o2. Just a regular air pump getting regular air from inside the cab and injecting it into the soil. Right now my cab lacks the ability to do air exchanges in a fashion that would allow Co2 ppm's to stay at a constant. If i were to hook up my Co2 system, it would be a waste. Especially since i'm not using an HID for veg. I wouldn't mind making one of those DIY Co2 pumps with a 2 liter bottle and starch and what not, LOL........memories....... Yes I know the passive intake should be larger, i just like more air flow and my plants haven't complained so.......

Ok so the single biggest reason of wanting to try this is the mere fact that it can take 2-3 days between watering/feeding. I am doing this in an attempt to water/nute more often. I know that the moisture naturally dries when the plant roots absorb the moisture. With this pump pumping air into the soil, it should dry faster and allow me to water/nute more often.

I decided to set the timer for 30min on and 30min off 24/0. I think this would definately be enough to at least show signs of growth promotion. We shall see......

Here are some of my past grows------> Cannabis Forums Message Boards - Medical Marijuana, Cannabis Club, Dispensary, News

And here are the pics of my current grow......nothing impressive.........yet
