How long before roots drown?

[Pankace]

I'm having a problem in one of my DWC air pumps. The tube keeps popping off randomly. I'm about to fix it as we speak but I was concerned for the plant. I don't know how long it sat without air for the roots. She still looks good and roots look okay. Has a slight tint now but I'm wondering if it's just from nutes.

I think a couple hours but not certain.

Not sure sorry. as for the air hose, the end of the hose may be a bit stretched. Used to happen to me as tubing aged a bit when I kept lots of aquariums. Trim a tiny bit off the end of the hose. or depending on your model of air pump you might be able to use a cable tie or some sort of small hose clamp.

Yeah I ended up trimming the stretched tip off. If it doesn't work I'll just use some adhesive to the outside of the pumps prong thing. I'm not going to have to worry about retrieving the tube cuz after this grow I'm upgrading the air pumps. These pumps were cheap and don't deliver much in terms of air.
