How do you interface a 1" PVC pipe with a 1" vinyl tube

So I'm building an under current system with a few buckets and I'm trying to construct a build which doesn't connect all buckets to one another with PVC pipe. Instead, there is a small 1 foot length of 1" dia PVC pipe inserted into the side of each bucket through a Uniseal. The PVC protrudes from the outside of the bucket only a few inches, at which point I'd like to attack a 1" ID flexible vinyl tube so that the buckets are movable and the system is not rigid.

I know that the vinyl tube is connected to a barb, so then the question is how to connect the PVC tube to the barb, or the vinyl tube? Any ideas?
I suck at plumbing and have spent hours at Home Depot trying to mix and match the right parts and connectors but something is always the wrong size.
I know there are lots of clever DIYers here so I thought this'd be a snap for someone with experience

Would a barb like this slip inside the 1" PVC tube and be glued to it?

go to lowes and they sell pvc connector with a barb on one end and a female coupling on the other side. I believe they have a straight 1' to 1' as well if not might just have to finagle a few connectors together.

It's infuriating I tell you! I don't really have a Lowes near me, but if that's where I have to go, so be it. Home Depot is just not getting it done. I think I need a non threaded, 1" slip barb but I'm not positive. I was also hoping to be able to do it without PVC glue but that may not be a possibility.

Just take a small piece of the vinyl tubing with you. Im surprised HD didn't have the connector. I do know lowe's does though. I see them all the time. With the right barbed connector you shouldn't need glue. Best bet would be hose clamps instead much easier to work with.
