Just curious 
.
So I’m prepping for go number 2 since pods and other extras arrived today. I have a seed germinating in water this time. 
I haven’t opened my Grobo since last week, and it was a couple days after that that I thought to end my grow. I opened it tonight to this. No bubbles.
Does the air pump stop with end grow? I thought bubbles went all the time.
They did stop once during last grow attempt but a quick something woke the pump back up, I was too panicked to make a note and don’t think I even mentioned it here…
Oh yes, drain/fill, because I recall when it finished draining the bubbles returned with just that little bit of water left.
Does this mean I’m going to have a fickle air pump?
Am I getting ahead of myself? I was hoping that was a one time thing.
I do have an extra air stone around here somewhere that I just bought and already misplaced. 
PS. Please forgive me- there’s no solution left in my tube for my probe since I knocked it over and I haven’t gotten those extras yet. Figured I could leave water in the unit until I got another pod or grab some res water for the tube and get to cleaning. The only reason leaving the sensors inside the unit with water won out was because I thought the oxygen bubbling in the water would be better for the probes than sitting in stagnant water. But they are nonetheless… And no, if I’ve no solution to store anything, I can’t calibrate anything either. Not yet. Hacks??
