As life would have it my Ph pen has gone for a s**t, and I have 10 brand new seedlings (10 days old). I just moved them into my bubbler and I have no idea how to manage the next two days. Anybody out there have any ideas. I am in Ontario Canada and everything is closed tomorrow and I need to check my ph? Help

go to Big'boxmart, and buy a basic ph tester kit in the pool or aquarium section.
that will get you in the ball park goodluck

in the future keep i journal of how much water needs how much ph up or down really helps with things like this and taking care of other problems that arise.

Thanks people...I just hope walmart is open? It's Canada and a hoilday, i'll try around ten and let you know.
