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......
