Oxygenating water

I read a thread about some guy using sparkling water to water his plants and thought about ways to add oxygen to water.

Do you think either running a fish tank air pump into a jug of water for a couple hours, or just shaking the shit out of the water would improve oxygen absorbtion by the roots?

I watered on tuesday early afternoon till i got a slight bit of runoff (its sat night now). On thursday night/fri morning we got 1.2 inches of rain and on friday we got 2 inches. The weather has been average to high humidity and temperatures from 80-90. Tuesday, wednesday, and most of thurs was sunny but the soil was still more wet than i would like to wait before watering.
Anyways Im curious as to how long it takes for overwatering to damage the plants.. they are 13 days old and most have 4-8 leaves and the two that are 17 days old have 18 leaves and 8 (bigger) leaves.
I checked them at 8 tonight and they are still very wet even after a day of solid rain so i broke up some small sticks (1/4-1/2 inch wide) and set the pots on top of them... is this ok to do? T

The ground they are sitting on was so damp and was preventing water from draining. And when should i start fert with 10-2-1 bat guano and how much should i start with? Soil is unfert. sunshine mix and 10-15% worm castings.

If your soil has good drainage it should be ok. If your getting too much rain you can cover the opening of the pot to help divert rain water away.

i mix up 32 gallons at a time. i don't use it all at once over a 2 week period. i have no air pump in the water, however i do blow threw a 3/4"pvc pipe to mix up my nutes again b4 turning on the pump. i have seen no illefects from no oxegen in the water,. you do want gooddrainage this also alows for some air getting to the roots as long as youlet the soil dry out b4 watering again. this is very important and criticaltoa plant.
