Hey gang.
I was wondering how long Ro water ph’d with some cal will stay phd in a sealed jug. Probably not long I imagine? I want to give some one some water that doesnt have a ph meter or up or down yet . However they just sprouted 5 seeds. I am giving them some happy frog mixed with perlite also. So I just want to give them some water so they dont give 7.7 ph water to their seedlings. Or is ph 7 bottled water going to be ok for them until they get their equipment
