all right i was thinking the other day,you use air pumps for oxygen in your water to get it to the roots,could you utilize a pure oxygen tank in line with your air pumps to add more oxygen to the water and if you did do you think it would greatly benefit the plants.i was thinking like a small amount of pure medical grade oxygen.any response would be great,this is for now a hypothetical question.
I dont think it would be enough of a benefit to counter the cost. The plants can only use so much oxygen, a lot of it would go to waste. Interesting thought tho.....
