Best bucket/res connectors

It’s strange that I can’t find any info on this in the grow/build journals I’ve read. I saw one post about it a while back, but I can’t find it now.

Anyway, I’m about to enter the build phase of my first grow. I’ll be ordering a tent this week and I want to set up a rdwc system with two 5 gallon grow buckets and a res. Thinking about am air stone in both buckets and the res and drip rings on each grow bucket for quicker early growth and circulation.

But I’m getting ahead of myself as usual… My question is: What to use to connect the the three buckets? I’ve seen many people use pvc pipe, but what are good flanges to use so I don’t end up with leaks?

And if anyone can point me to a good dwc build journal I would be very grateful. I’ve seen a few but I would like to see which are admires or recommended by experienced growers.


Ok, I think I found something. Uni-seal tank adapter. Is that what you all use?

Uni seals work great on square stuff. There’s some black square 5 gallon buckets with lids on Amazon. Barely more expensive than regular buckets but it’ll make life easier. And black is better for keeping light out.
