Hello everybody, I need some help please, I would like to understand why the pH of my water is different when I keep it in the dark (about 6.5) and when I leave it in daylight it goes down (around 5). Just one more thing, when I keep in the dark, temperatures are lower than when in light (-10 C0 of difference), if this is important for my pH question. Does anybody in this list grows Phrag sargentianum? I have a problem with its roots, I mean he refuses to this for me, but it mades leaves instead. I would like very much to know some of your culture program for Phrags... Cheers
Olga
