O2 Injections to Roots......
So I have an extra aquarium bubbler air pump. Decided to run tubing into the bottom of a couple pots to inject some O2 directly into the soil. I've been wanting to try this for a while and decided to go ahead. I set the timer to run for 15 min every hour of light. On 18/6 right now. My thoughts on this are that roots love to be in an oxygen rich environment so by directly injecting O2 into the soil, it should promote growth. I'm going to keep an extra eye on them to see if it does make a difference.
Has anyone tried this?

I love it! Another experiment! So tell us more about the setup. Where are you at in the grow and are you running this against plants who do not have the oxygen drip as a control? I am curious what would happen if it was set up on a 24/7 cycle every 15 minutes too since many believe that the root systems grow more in the dark cycles, but that could be for a follow-up experiment if this one shows that there is an effect. I am going to pull up a chair and watch this!

Cool, thanks for joining in Emmie.
As for my setup, veg cab is 36"w x 22"d x 24"h, 4 cfl's 9400 lumens total, two plants right now, Purple Cap, in Happy Frog soil. 4" inline exhaust fan 80 cfm, 4" passive intake on opposite side of cab. They are about to start day 11 of 18/6.
Nutes: Fish-Mix, Alga-Mic, Bio Bloom, Top Max, Kool Bloom, Bat Guano.
I was going to inject both pots but for experimentation sake I will only be injecting the smaller one of the two. Right now the smaller one is about half the size of the other so if it is beneficial, it should show.
Will post pics tomorrow.

Correct me if I'm wrong, but don't the plants use O2 in the dark and co2 during the light? Why are you adding o2 during the light cycle? Shouldn't it be co2 during light and o2 during dark? I'm very interested in seeing if it does anything as your doing it...subbed!
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!!!

oooo... i didnt catch that. Are you using O2 or just pumping regular air into the soil using the aquarium pump?

Sorry, missed this...passive intake should be 1/3 larger than dynamic exhaust.

Dam sorry....I am too buzzed....just pumping "air"...DOH!...Thx Em! I thought you were using o2 out of a TANK>>>>LOL! Still....what I said applies...I think....wait....yea...maybe....aw, I'm just gonna go lie down for awhile now...BBL...:stoned:

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:D

13 hours after starting the air pump and timer and watering each pot with 1cup of water, the amount of moisture in the pot with the smaller plant is less than the larger one. The effect of the air pump is working the way I thought it would which is good. What I don't know is if this will be, overall, beneficial.
I used a moisture meter to determine the amount of moisture, ranges from 1dry - 10wet. After 13 hours, at a depth of 3" into the soil, the big plant read a 7 and the smaller a 6.
At hour 17 I will recheck the moisture meter at same depth and see the difference......

There has got to be more evaporation with the air flowing through too. How much of the water use is that and how much is the plants using more is the question. What I am worried about is that just like what happens when the roots come in contact with the air in drainage holes and it cuts them off, that you somehow will hurt the roots in the middle of the root ball with this air flowing in. I'm wondering if the "oxygen" has to be attached to the water molecules to be beneficial to the plant. We shall know soon I suspect.
