Auto crafting honey block farm

An automatic honey block farm. Eight bee nests sit in a line under flowering azalea leaves with a dispenser in front of each, and a comparator reads every nest so the dispenser bottles the honey the moment the nest fills. Hoppers carry the full bottles to two crafters, which turn every four into a honey block, and the blocks drop into a barrel. A soul sand bubble column with kelp above it lifts the empty bottles back up, and a water stream across the top redistributes them into the dispensers through a dropper, so the glass never leaves the farm. It primes on 80 stacks of glass bottles, which is the real cost of the build.

Ignore the closing advice to build this in the Nether. The farm needs water and you cannot place it there. The End works and gives the same permanent daylight, which is the point of the tip.
If you do want it in the Nether, replace the water stream on top with a line of hoppers and the bubble column with droppers. areshy3784 and AirBear-s9k both did that successfully.
Fill every slot of every dispenser with glass bottles. A partly filled dispenser is why honey bottles pop out at the nests instead of going into the hoppers below.
Empty bottles get stuck in the hoppers under the water stream. aronberns8299 puts a bottom slab one block above the stream to fix it, Debonko shifted the dropper line instead on 26.2.
kydenHWBT found the farm stops when the crafter fills up. Empty it and it runs again.
Swap the glass bottles for shears if you want honeycomb rather than honey blocks, the rest of the build is the same.
