Hello, emily's garden uses an air pomp as my bubbler. The aquarium seller just told me that to adjust the PH of water with ph minus i have to reduce the air apport in the water. The problem is that ait in the water is the basic of that kind of hydroponic system. So i made an experiment. It seems that the ph is rising immediatly after putting the air stone in a PH 5.5 solution. And after a second balancing, it is quite stable. The experiment is to prepare water with air stone and acid, PH 5.5 or 6, and to wait until it stable, and after putting nutes in it and feed the plants.
I wonder anyway how does Que Bud who uses bubbler systems ...
Que Bud, any advice ?
