Question from a fellow grower:
I have a fairly simple idea for introducing a controlled amount of pure oxygen to roots in soil mix after watering (for a small home grow). I was thinking about doing this with some outside plants in soil and smart pots. Can you tell me if I am way off base?
The idea is to fill the balloon with oxygen after watering close cylinder valve and allow the balloon to blow out the 02 from the balloon into the soil; metering can be done by the valve as well as balloon selection. Lastly I was thinking with the right balloon material the pressure from the balloon would decrease as oxygen makes it through the soil and the balloon empties… for some reason I like that.
See attached; the sketch that lets say my monkey was kind enough to make is not to scale: only small diameter lines would be needed.
