Best grommet source for buckets?

Trying to find the best grommet for tight seals on buckets. Tried several already and not liking them. Thanks

GH Makes good grommets. What size barb are you using? 3/4" 1"?

The key is a clean smooth hole with no nicks or burs.

A sharp spade bit will make a perfect hole so long as you have a gentle touch and go at a slow speed. If you let it catch and gouge then it will fuck up the hole quick.

A step bit will make nice clean holes but you gotta be careful not to go too far and you will want an inside deburring tool to finish the back side of the hole.

This is a cheapo https://www.amazon.com/Uniweld-70072-Inside-Outside-Deburring/dp/B00HNQR53E

What you building?

1/2" isn't something I like for any sorta return or waste drain. Plugs up too easily.

3/4" can work if roots aren't involved lol. If you got a RDWC going them you want 2 or 3 inch PVC and bulk heads or if you are feeling lucky uniseals lol.

Generally bigger is always better, to a point anyways. We don't need a 6 inch pipe going into a 5 gallon bucket lol.

Currently have a 5 gallon bucket, has 1/2” lines to reservoir. Planning the upgrade for the next grow.

Well I would highly recommend the 1 inch with your 5 gallon RDWC buckets.

If you change to a flat sided container for your sites then you can go with the larger bulkheads and PVC.

Depending on how big your plants/roots are you may not have a problem with 1 inch or maybe even 3/4. Bigger plants are gonna need bigger returns to prevent plugs on a RDWC. Nothing beats a 3 inch with bulkheads and a large capacity tote for a site and reservoir if you are growing trees in RDWC.
