Hi,
Is it bad that the roots are hanging all into my tank?
If yes, how can I prevent this without Investing in a new system?
If no, should I add an airstone/s to provide more oxygen?
Or don’t do anything.
Get some airstones in the res. I would stop top feeding as your water will eventually struggle to run back into the tank and then flood everywhere. So from now it's going to be a dwc in effect. You could carry on top feeding but it may flood. Good luck
Hello. Yes add a air stone. It's been found that the exposed roots will take oxygen through their roots. But cannabis loves oxygen in the water. Or instead of a air stone you might want to try Hydrogen Peroxide. I mix 1 ounce of 29% HP to 5 gallons of water when I change my solution once a week. Chuck.
