Looking for a drop-in bucket water pump+wand

I have an indoor grow tent with San Pedro cactus.

I’m imagining a watering system where I can make a 5gal bucket of ph adjusted- nutrient solution, drop in a sump pump or something, and water each pot with a wand.

Instead of having to dip in my watering can a dozen times.

Big plus if the pump can run on 18-24v DC so I could power it with my Milwaukee batteries of which I have a surplus.

I’d imagine this is something that would already exist… I’m just having a hard time finding them/knowing what to search.

Thanks!
