Guys, when you're building this farm, do not forget to put one random item in the hopper/dropper clock two blocks right of the on/off switch! Without that the farm won't turn on.

4:46 You forgot the other 3 great alternatives: end portal frames, ender chests, and enchantment tables

[greybeardmc]

I love how you and DocM are tag-teaming the builds. First I see a slime farm on your channel then he builds it. He also builds a moss / bonemeal farm and I see it on your channel. Keep it up!

[PrinceFlumph]

The other thing with the bonemeal dispenser being put underneath is it allows for the top to be put on display, makes it look a lot cleaner and more fancy!

To those wondering: This farm still works in 1.19.4, on singleplayer as well as on multiplayer servers. If the farm is not working for you, there could be several reasons:
1. Make sure you have an item in the hopper clock near the lever that powers the farm. Any item will do, but the farm will not operate without it.
2. Make sure all four dispensers underneath the farm are supplied with bonemeal. Technically, only one needs to have bonemeal to start, but it will take the farm time to build up enough bonemeal to feed the other 3 dispensers. If you want the farm to work and produce bonemeal right away, you would want all four dispensers to be completely full of bonemeal.
3. If the farm's lava keeps turning to stone, it is because you are leaving the chunks the farm is in. If the farm unloads and reloads, especially if it is built on a chunk border, the lava will turn to smooth stone, and the farm must be reset, which is a real pain to do. For best results, make sure that after you turn the farm on, you don't leave the chunks or log out until you turn the farm off again. Also, if your farm breaks and you have to reset it, make sure you remove the cobblestone that forms and don't let any of the pieces fall into your hoppers that feed the composters. If this happens, it will clog one of the composters, reducing your rates.
4. If the farm is STILL not working for you, make sure that you have built it correctly. All of the observers must be facing the right way and all of your repeaters must have the appropriate tick delay set. Use litematica and take a schematic when building to ensure you haven't missed any pieces.
5. This farm for sure works on a vanilla server as well as a fabric server. I can not say if it also works on a forge server, but maybe someone else can reply and verify that.

Such a clean design and it's so satisfying to watch it working

This is sweet! I think I saw one of the versions in docm77’s video and I’ll probably use this in my smp with my friends. Great farm!

[wetnoodle]

At 5:43, you mentioned that you have to fill in the farm with stone before running it for the first time - there are alternatives. You can use any block that can turn into moss in place of the stone. That means you can use dirt, granite, or even moss if you wish.

This farm need it a diamond ore for building block, improves the efficient by +30%

[mythicaleven]

Recently I did a 24/7 tree farm and was looking for a good bone meal farm. This one is perfect! Huge thanks for that ilmango!

This is a wonderful machine. Perhaps more accurately, it's a collection of machines all working together. Multiple ingenious timers, stone generator, collection system, moss generator, auto-composter... it's really incredibly how it all goes together.

i was wondering why doc's farm in the latest video had two-wide lava channels. now i know.

[onedozenbugs]

you need to replace the white concrete with deepslate diamond ore like doc so it works better 🙄🙄 /j

[mattarchbell]

If you disable the redstone line for the water flusher for the first cycle or two, you do NOT need to place all the stone by hand, just the stone under the waterlogged trapdoors

[LordAJ]

I built the old version in my world and I must admit it was a bit clunky to construct. This is definitely more elegant. Still no regrets building it; being able to funnel fully automatic bonemeal directly into my tree farm is a great feeling.

[mortcheman]

If anyone comes to a problem that some of the dispensers aren't converting stone to moss (although they are filled with bonemeal and there is otherwise seemingly nothing wrong with them), try putting something next to them (under the target block) that will cause them to update (a note block, a piston, etc.). It seems like Minecraft sometimes handles block updates incorrectly/unexpectedly.

[porpoise]

This is possibly my favourite Minecraft farm.

It is pretty simple and cheap enough most can build it while providing an extremely useful resource (to facilitate so many other farms) and looking really cool in operation. And the ease of setting up one as an early farm and just expanding it as needed is icing on the cake.

And a new, cleaner version is awesome.

[Tkonk]

Works great in 1.19 still! I had an odd issue with block updates where every other dispenser would use bone meal once and then not fire anymore (the rest of them worked normally). I put a piston below the adjacent redstone line facing the dispensers to update them and now it works great. It could be an issue with the paper server that I was running on.

[MTBiSLiVE]

Great farm as always, i've been using it for quite a while now, but recently noticed one issue (that i probably already had for quite a while, but i'll get to why i think that) while including some of the carpet autocrafting tables into my farms.

Sometimes moss carpets, seeds or (flowering) azealeas will make their way into the output (which in my case is rather unfortunate since it breaks my autocrafting tables and especially the shulker loader behind them. I think i had this problem for a while since in my previous version (without autocrafting tables) i used shulker loaders with filters, but couldn't remember why i built it like that.

My suspicion is that these random items make their way into the water stream by glitching through the glass next to the bottom moss block after the top of the moss block is cleared by the piston. I'll look into if i can fit a sneaky lava block that will burn those "artifacts" somewhere and see if that fixes my issue.

Update: My suspicion indeed turned out to be true and just adding lava next to the moss block that is bonemealed (basically add lava in the block that the piston pushes against, it will flow over the bonemealed moss block, but does not affect anything) fixes the issue and the output is 100% bonemeal now (tested for around 1 week runtime on my server).
