Nope. The bags don't hang. They just get pushed on to the "connector" Then you twist them to kinda confirm a good seating from bag to connector. The bags are pre-pressurized so don't need gravitational assistance.
The holes are 1/4", or you can also get away with 5/16 high helix bits. 5/16 may very well be the recommendation. 1/4" is so much easier to find and works perfectly fine, so that's what I use most.
I think the last box I bought, which was only 12 bags, was $26.81/bag. Which treats 5"dbh. I personally run the bags at $60/bag. Haven't been told to piss off yet. Lol. The thing is you are treating on a 5" increment. So, a 12" tree gets the same amount of product as a 15". So the pricing can be finicky when you start considering aj tree iv stuff going off exact dbh measurement.
With that said, it's been working out really well for us.
Happy to share a bit more info if anyone is interested. Gotta wrap a few things up tonight with work, then chill with the fam a bit.
Will try to kick in more info asap.
Or...Please ask what anyones specific questions/comments/concerns, and I'll address those specifically.
Good discussion here.
Yet one more reason to LOVE THE TH!
