Bonbon, do you think it would be of benefit to have the root mass in the presence of oxegen underpressure. For example using the misting system, a rubbermaid containner could have holes in it just large unough to house the junction fo the stem and the root. that way the plant's roots could be sealed off from the outside air, and possibly pressurised with a can of Oxegen. Would that, with a bubler, increase the ammount of oxegen available to the root system, and would such an increase be of benefit?
