I have just checked my PH and it is already 8.5 high, 24 h after being 6.5. I think that the bubbles go to the rockwool and go back down to the fert /water solution with a high PH. I don't think that i have to balance my PH every day...
I did not have this problem with waterfarm and vermiculite. Any one with bubbler/rockwool experience ?
Thanks

fhydro Reviewed by fhydro on . Questions about PH Hello, after putting some seeds into rockwool cubes, there are now in a bubbler system. The roots are growing fast but the leaves seem to be stopped. I checked my PH solution : 9!!!. I made a new mix which is 6.5 PH. 1/ Is it normal to experience a slow growing in a 9 PH solution ? 2/ Why the PH is increasing so fast ? Is it a rockwool pollution of water ? Thanks for advises Fhydro Rating: 5
