Hash and Concentrates

Home › Hash › Hash and Concentrates

The resin, taken off the plant three ways — sifted dry, washed in ice water, or rubbed off a living plant with shears — and then pressed into hashish, filtered hashish and rosin. This page walks the whole bench from the first box of kief to a moon rock, with the exact numbers, and tells automation fans what can and cannot be piped. Everything here is new in 2.1, and works the same on Fabric and NeoForge, on Minecraft 26.3, 26.2, 1.21.11 and 1.21.1.

Note: hash is for smoking and only for smoking. Nothing in the hash family goes into the Decarboxylator, the Infuser or a furnace, and none of it makes cannabutter. For edibles, see Cannabutter.

Seven buds still make nine smokes: the box turns 7 buds into 9 kief, and the press turns each kief into one hashish without taking anything for it. What sifting costs you is the strain — kief is kief, whichever plant it came off.

JEI and REI (and EMI on 1.21.1) show all of it in game: the Dry Sifting, Ice-o-lator Wash and Pressing pages, and an In the World page for cutting a bar and rubbing a plant for charas.

Your first hashish

1. Craft a Sifting Box and put it down anywhere.
2. Right-click it with buds, one at a time, the way you fill a composter. Seven buds fill it; a second later it is ready.
3. Right-click it again with an empty hand: nine Kief pop out on top.
4. Craft a Hemp Press, set it on a lit campfire (or a magma block), right-click it and put the kief in. Ten seconds a piece, and out comes Hashish.
5. Smoke it in a pipe, a bong or a vaporizer, or roll a pinch into a spliff with a bud. It gives Night Vision.

Sifting Box

New in 2.1.

A tub with a screen in it. Plant matter goes in on top, the resin falls through, and the box hands you loose powder nine at a time. It has no menu and no fuel: it works exactly like a composter.

P B P
P C P
P P P

P = Hemp Planks Slab · B = Iron Bars · C = Hemp Canvas → Sifting Box

It is vanilla's composter with its two holes filled: the iron bars are the coarse grate you beat the plant against, the canvas the fine screen the resin falls through. An axe breaks it fastest. It does not burn.

Filling it

Right-click with something it takes. Each item either moves the screen up a level or doesn't, and seven levels fill it. One second after it fills it settles and is ready, with the composter's "ready" sound. You can mix buds and leaves freely, and a level that would go past full is simply lost, as in a composter.

What it takes is decided by four item tags:

Tag	Holds	Each one moves the screen	One batch takes	Out
#hempdustry:siftable/flower	Purple Kush Buds, Lemon Haze Buds	one level, always	7	9 Kief (or 9 Bubble Hash in a wash)
#hempdustry:siftable/resinous	Beldía Buds	two levels, always	4	the same
#hempdustry:siftable/trim	Hemp Leaf	one level, 15% of the time	about 47	the same
#hempdustry:siftable/kief	Kief	one level, 25% of the time	about 28	9 Filtered Kief (dry only)

• Beldía counts double because it is the resinous one, grown for the sieve — but its kief is the same kief. See Strains.
• About 47 leaves is about ten plants' worth of trim. Those leaves would otherwise go to the Decarboxylator one for one, so a batch of trim is either nine smokes or a lot of cannabutter: a fork, not a ladder.
• Schwag is in none of these tags. The box turns it down.

You can hear whether an item took: the composter's "fill" chime when the screen rises, the duller sound when it didn't.

Filtered kief — sifting kief again

Empty a box, then fill it with Kief instead of plant matter. Each kief moves the screen only one time in four, so a batch takes about 28 kief and gives 9 Filtered Kief — about three kief for each one, or roughly 22 buds' worth of plant for nine. That is the price of the dry road to the blonde end of the family. Filtered Kief presses into the same Filtered Hashish the ice wash leads to; the wash just gets there on far fewer buds (below).

Only kief re-sifts. Bubble hash and filtered kief are already the clean end of their road.

One screen, one kind

Plant matter and powder never share a screen. The first item into an empty box decides what it holds until you take the batch out. When the box turns something down for a rule you can't see, it says why on the action bar:

The box is…	You offer…	It says
filled with water, without ice on all four sides	buds or leaves	The wash needs ice on all four sides of the box
dry, part-full of kief	buds or leaves	You can't mix leaves or buds with kief
dry, part-full of plant matter	kief	You can't mix kief with buds or leaves

Everything else it won't take, it refuses in silence, as a composter does: an item that isn't in a tag (a stick, schwag), any item while the screen is full and settling, kief offered to a wash, and a water bucket on a box that already holds water or has a dry batch under way (the bucket stays full).

Taking the batch out, and breaking it

• Right-click a ready box with an empty hand, or with anything it doesn't take. The nine pieces pop out on top and the box goes back to empty and dry.
• Break a ready box and the batch comes with it, nine pieces, the way a full composter gives up its bone meal.
• Break a box that is still filling and it drops only itself. Whatever was on the screen is lost, and so is any water in it.

Automation: none, on purpose

The Sifting Box has no inventory at all, so there is nothing for a hopper to work with. A hopper pointed at it keeps its items; one underneath finds nothing to pull. The same goes for item pipes from other mods. You fill it, water it and empty it by hand.

What it does offer:

• A comparator reads it like a composter: 0 when empty, rising with each level, 8 when the batch is ready. A lamp on the other side tells you when to come back.
• A piston can push it, contents and water included, and a full box still settles after it moves.

The ice wash (the Ice-o-lator)

New in 2.1.

The same box, washing instead of sifting. Fill it with water, pack ice against all four of its sides, and plant matter washes out into Bubble Hash — the blonde, clean end of the family. ("Ice-o-lator" was a brand of the mesh bags, never a machine, so in this mod it is the name of the wash.)

1. Pour a Water Bucket into an empty box. Only an empty one: a dry batch that is part-way stays dry. You get your empty bucket back.
2. Put ice on all four sides — north, south, east and west. The top and bottom don't matter.
3. Feed it buds or leaves exactly as you would a dry box. Kief does not go in a wash.
4. Take out 9 Bubble Hash when it's ready. The water is spent with the batch; the box goes back to dry.

A visible advancement, See You Ice-O-Later, marks your first bubble hash.

Watch out: once a box is filled, the water stays until you take a batch out. There is no scooping it back up with a bucket. If you change your mind, break the box (it drops itself) and put it back.

The jacket sets the price

The weakest of the four sides decides the rate, so three blue ice and one plain ice is a plain-ice jacket. If any side isn't ice at all, the wash stops. The rate multiplies each item's chance: in packed ice a bud moves the screen three times in four.

Jacket (all four sides)	Rate	Purple Kush / Lemon Haze Buds	Beldía Buds	Hemp Leaf	Melts?
(dry box, for comparison: makes Kief)	—	7	4	about 47	—
Blue Ice	100%	7	4	about 47	no
Packed Ice	75%	about 9	about 5	about 62	no
Ice (or Frosted Ice)	50%	about 14	7	about 93	yes, in bright light

Even at its best the wash only matches dry sifting and never beats it: what it buys is the blonde product, not more of anything. Below blue ice it is a worse yield than staying dry, and that is fine — the dry box is right there.

• Plain ice melts in bright light (block light above 11 — a torch or lamp nearby, not the sun), as vanilla ice always does. Light the room and the jacket quietly turns to water and the wash stops. Build your wash room dark, or pay nine ice a block for packed ice and stop worrying. Packed and blue ice never melt.
• Frosted Ice counts as plain ice, so Frost Walker boots will keep a jacket alive — for exactly as long as you stand there.

Tip: watch for frost. While a wash is cold and working, snowflakes drift up off the water. No frost on a filled box means a side has melted or is missing; the box tells you why the next time you try to add something.

Hemp Press

New in 2.1.

A screw press on a hemp-brick bed, heated from below. It is the bench's one machine: it turns powder into hash, hash into rosin, and retted stems into fibre.

B B B
B P B
B B B

B = Block of Hemp Bricks · P = Piston → Hemp Press

It needs a pickaxe to drop when broken. It does not burn, and it gives off no light of its own.

Heat from below

The press works only while the block directly underneath it is hot — the same rule as the Infuser. What counts is the block tag #hempdustry:heat_sources:

Counts as heat	Note
any Campfire (Soul Campfire too)	only while lit
Furnace, Smoker, Blast Furnace	only while burning
Decarboxylator	only while burning
Magma Block	always
Lava, Lava Cauldron	always

When it's hot you see it: the bed plate and the grate on the front glow red, wisps of steam rise off it, the screw creaks now and then, and the flame lights in its screen. The press puts a parchment packet on the bed and screws the platen down while it's pressing.

Tip: a magma block needs no fuel and makes no smoke — the tidiest heat for a press you want to watch.

Using it

Right-click it to open its screen: one input slot, one output slot, and a flame that shows whether the heat is there. Only things it can press go in the input slot, and shift-clicking sends them there.

It presses one piece every 10 seconds (200 ticks), so a batch of nine takes 90 seconds — what a furnace takes for nine iron. Lose the heat, or run out of room in the output, and the progress cools off rather than freezing. A server can change the speed with machineSpeedMultiplier in the config's world section (Configuration).

Its five recipes, one piece in each time:

In	Out
Kief	1 Hashish
Bubble Hash	1 Filtered Hashish
Filtered Kief	1 Filtered Hashish
Filtered Hashish	1 Rosin
Retted Hemp Stem	8 Hemp Fiber — two more than by hand in the grid (Hemp Materials)

Pressing hash is one for one and loses nothing: it changes a powder's shape, not what's in it.

Watch out: the output slot holds one kind of thing, up to a stack. If it's holding hashish and you switch the input to bubble hash, the press waits until the hashish is gone. Empty it first, or let it pour out the back.

Automating it

In: a hopper above it or against any side feeds the input slot, and so does an item pipe from another mod. Only pressable items go in.

Out: it pours out of its back. The underside is where the heat is, so a hopper can never sit there on a working press. Instead the press pushes what it makes over the little pour lip on its back — the side opposite the glowing grate, which is the side facing away from you when you placed it — into whatever stands there:

• a chest, barrel, shulker box or hopper,
• a storage minecart on a rail behind it,
• an item pipe from another mod,
• or a second Hemp Press.

It pours one item every 0.4 seconds, a hopper's pace, so it empties exactly as fast as a hopper under a furnace would. With nothing behind it, what it makes stays inside — it never spills on the floor. A full chest behind it just makes it wait.

Chaining two presses. Put a second press, with its own heat underneath, behind the first. The first presses bubble hash (or filtered kief) into filtered hashish and pours it into the second, which presses it into rosin and pours that out of its back into a chest. Nobody touches either. Feed the first from a hopper and the whole blonde line runs on its own.

  seen from above, you standing at the bottom

   [ chest ]
       ^  pour lip
  [ press 2 ]    filtered hashish -> Rosin       (heat under it)
       ^  pour lip
  [ press 1 ]    bubble hash or filtered kief -> filtered hashish   (heat under it)
       ^
      you        both placed facing you: the grates face you, the lips face away

Only the blonde line chains. Hashish and rosin are not pressable, so a press pouring either into another press is refused: the pieces stay in the first press, which fills up and stops. Put a chest behind anything that makes hashish or rosin. A row of presses side by side never pour into each other; give each its own chest behind it.

• A comparator reads how full the press is, as it would a furnace.
• An anvil name sticks. Rename the press in an anvil and the name titles its screen and stays on it when you break it.
• Break it and whatever is inside spills out.

Hash carries no strain. A hashish sifted from Purple Kush and one sifted from Lemon Haze are the same hashish — the trade names hash by how it was made, never by the plant. Its colour follows the process, and promises nothing about strength: dry-sifted and pressed is brown, filtered and ice-washed is blonde, hand-rubbed charas is near-black.

Kief, Filtered Kief and Bubble Hash

The three loose powders. None of them is smokeable: loose powder falls straight through a bowl's screen, which is why the trade presses it. Each has two uses:

• Press it — Kief into Hashish; Filtered Kief and Bubble Hash into Filtered Hashish.
• Coat a moon rock with it — Kief counts as hashish there, Filtered Kief and Bubble Hash as filtered hashish. Pressing is lossless, so a loose coat costs nothing extra; it only saves you a ten-second press.

Kief also re-sifts into Filtered Kief (above).

Hashish, and the Hashish Bar

Hashish is kief pressed with heat: brown, and the everyday hash. Smoked, it gives Night Vision with the hash body of Resistance, Slowness and Hunger (Smoking hash).

Nine of it make a Hashish Bar, a stash you can see:

H H H
H H H
H H H

H = Hashish → Hashish Bar

• Place it like a block. It lies across your view, and the cuts come off its right-hand end, so you can watch it shrink.
• Cut it by right-clicking with a blade — any sword, even a wooden one, or a modded knife (#c:tools/knife). Five cuts give 2, 2, 2, 2 and 1 pieces, nine in all, and each cut costs the blade one point of durability. Shears won't do it; in this mod they trim plants.
• There is no way to unpack it in the grid. The blade is the way back, and that's the point of the bar.
• Break it and an uncut bar drops itself; a part-cut one drops the pieces still in it.

Filtered Hashish, and its bar

Filtered Hashish is the blonde hash, pressed from bubble hash or filtered kief. It gives exactly the same high as hashish — Night Vision and the hash body — with half the chance of greening out. Smoother, never stronger. It is also what the press turns into rosin.

The Filtered Hashish Bar is the same as the brown bar in every way: nine pieces in the grid, five cuts with a blade, nine pieces back.

Charas, and the Charas Ball

Charas is resin rubbed off a living plant. Take shears to a ripe plant — its last two growth stages — and you snip one hemp leaf, always, with a 1 in 4 chance of a pinch of charas. It works once per plant; the plant keeps growing and harvests as usual, one leaf lighter, and shears on it again say Already rubbed. A sticky, honey-like sound means you got some. See Growing Hemp for the trim windows.

• Plants grown under any light the plant counts — a Grow Lamp, a redstone lamp, even glowstone — and plants that were stressed, give it half as often: 1 in 8. Charas is a field craft (Indoor Growing).
• It needs no block at all, so it is the hash you can have on day one. And because it is a right-click on one particular plant, no machine will ever do it for you.
• Smoked, it gives Slow Falling with the hash body.
• Charas is never pressed, so it has no bar. Nine of it roll into a Charas Ball instead, and a ball pulls apart into nine charas again in the grid.

C C C
C C C
C C C

C = Charas → Charas Ball · and one Charas Ball → 9 Charas, in any slot

The advancement for your first pinch is Sticky Fingers.

Rosin

Rosin is filtered hashish pressed again: the most concentrated thing in the mod, and the plainest to smoke. It gives the hash body — Resistance, Slowness, Hunger — with no Night Vision or Slow Falling, and keeps filtered hashish's half chance of greening out.

• One piece fills a whole bong bowl: a single rosin is a dose of three.
• Bong only. The Wooden Pipe's bowl holds two and the Redstone Vaporizer's one, so both turn it down, and it doesn't roll into a spliff.
• It is also the glue of a moon rock.

Moon Rock

A bud dipped in rosin and rolled in a coat. Any arrangement of:

• one Purple Kush Buds, Lemon Haze Buds or Beldía Buds,
• one Rosin,
• one coat:

Coat	Any one of	The coat adds
brown	Hashish or Kief	Night Vision
blonde	Filtered Hashish, Bubble Hash or Filtered Kief	Night Vision
black	Charas	Slow Falling

→ Moon Rock, named after its bud — "Purple Kush Moon Rock" — with the coat on a line underneath.

What it does. A moon rock packs a bong with a full bowl of its bud's strain, three buds' worth, with a pinch of the coat on top. The coat brings its own effect and the hash body, and it lifts the bud's helpful effects one level past the usual cap, to level III — the only way a bong gets there. The bud decides everything else, the chance of greening out included, so a blonde coat is no gentler than a brown one, and a moon rock sits at the top of the green-out odds. Its third bud buys the level, not time: a moon rock lasts a bong's plain 50 seconds, where a bong of three loose buds lasts 75. Beldía's Invisibility has no level to raise, so a Beldía moon rock is a shorter Beldía bowl with the coat's effects on top. Smoking has how the levels and the green-out work.

• Bong only, one moon rock to a bowl, and not together with loose buds.
• There is no moon-rock spliff, and schwag doesn't make one.

Hash spliffs

A pinch of Hashish, Filtered Hashish or Charas rolls into a spliff with one or two buds of one strain:

B H          B H B
P P          P P P

B = that strain's buds · H = the pinch · P = Paper → a Spliff of that strain, "With Hashish" (or whichever) on a line underneath

A joint needs something to burn, so there is no spliff of hash alone, and the loose powders and rosin don't roll. Pairing a bud with a pinch lifts the bud's helpful effects a level: one bud and a pinch reach II, two buds and a pinch III. Smoking Gear has the spliff in full.

Note: a known issue in 2.1.0 — a hash spliff's name reads one level low: two buds and a pinch says II and gives III.

Smoking hash

What one piece of each gives, before the device and the dose have their say:

Smoked	Signature	The hash body	Green-out	One piece is
Hashish	Night Vision	Resistance · Slowness · Hunger	the usual odds	a dose of 1
Filtered Hashish	Night Vision	Resistance · Slowness · Hunger	half the usual odds	a dose of 1
Charas	Slow Falling	Resistance · Slowness · Hunger	the usual odds	a dose of 1
Rosin	—	Resistance · Slowness · Hunger	half the usual odds	a dose of 3 — a whole bong bowl

• Resistance and Hunger rise with the dose; Slowness stays at I, and so does the signature (a second level of Night Vision would be the same as the first).
• Hash bowls hold one material, like any bowl. To mix a bud and a hash, roll a spliff or make a moon rock.
• The dose, the cap at level II, green-out and the devices' durations are on Smoking.

Where each one goes:

	Spliff	Wooden Pipe (takes 2)	Bong (takes 3)	Redstone Vaporizer (takes 1)
Hashish, Filtered Hashish, Charas	a pinch, with 1 or 2 buds	1 or 2 pieces	1 to 3 pieces	1 piece
Rosin	no	no	1 piece	no
Moon Rock	no	no	1	no
Kief, Filtered Kief, Bubble Hash	no	no	no	no

Note: a vaporizer bowl of hash hands nothing back. Only a bowl of buds (schwag included) leaves scorched hemp behind, so hash never finds a back door into the butter.

Which should I make?

None of these is a strict upgrade on another. Colour follows the process, never the potency: a blonde hash is not a stronger brown one, and the black one is not the best.

	What it costs	Effort	What it buys
Charas	ripe plants and shears: about one pinch per four plants (per eight under lamps or stressed)	no blocks; by hand, for ever	Slow Falling, vanilla's phantom-membrane effect, from the start of the game
Hashish	7 buds or about 47 leaves for 9	a Sifting Box and a heated press	Night Vision in bulk, out of leaves you'd otherwise only cook
Filtered Hashish, dry	about 28 kief (some 22 buds) for 9	one more sifting pass	hashish's high with half the green-out odds
Filtered Hashish, washed	7 buds for 9 in blue ice; about 9 in packed, 14 in plain	building the ice jacket	the same, far cheaper per bud
Rosin	one filtered hashish each	one more press, which can be chained	a full bong bowl from one piece, just as smooth — but no Night Vision
Moon Rock	a bud, a rosin and a coat	crafting	the bud's helpful effects at III plus the coat's signature — at the top of the green-out odds; bong only

In short: charas for a cheap, permanent Slow Falling; hashish for Night Vision by the stack; filtered hashish when you're tired of greening out; rosin when inventory space matters more than Night Vision; moon rocks when you want the biggest hit there is and can live with the odds.

Why there is no wax or shatter

Real-world "wax", "shatter" and "budder" are mostly made with butane, and solvent extraction is the one step of the whole business best known for blowing up kitchens. We'd rather not put that in the game, even as an abstraction — and we don't need to, because a press gets rosin to the same top shelf with nothing but heat and a screw. "Wax" is a texture rather than a method anyway; rosin sets up waxy too. So if you came looking for dabs: it's rosin, it goes in the bong, and nobody had to open a can of lighter fluid.

For pack makers

Recipe type, tags and data

• hempdustry:pressing is the Hemp Press's recipe type: one item in, one stack out, and all five recipes are plain JSON in data/hempdustry/recipe/pressing/. The ingredient is written the way each Minecraft version writes one. On 1.21.11:

  { "type": "hempdustry:pressing", "ingredient": "hempdustry:kief", "result": { "count": 1, "id": "hempdustry:hashish" } }

  26.2 and 26.3 write it the same way (a count of 1 may be left out). On 1.21.1 the ingredient is { "item": "hempdustry:kief" }. The result's count may be more than one (stems give 8).

• #hempdustry:siftable/flower, /resinous, /trim and /kief decide what the Sifting Box takes. The rates belong to the tags, not the items, and are fixed: one level, two levels, 15% and 25%. Add an item to a tag and it sifts at that tag's rate.

• #hempdustry:heat_sources (block tag) is what heats the press and the Infuser. A block with a lit state counts only while lit.

• #hempdustry:hash_cutters is what cuts a bar: #minecraft:swords and #c:tools/knife, both optional entries.

• The ice jacket is not a tag: Blue Ice, Packed Ice, Ice and Frosted Ice, with fixed rates.

• Hashish, Filtered Hashish, Charas and Rosin are strains with no seeds and no flower, in data/hempdustry/hempdustry/strain/, so a datapack can rebalance them or add a resin of its own. Rosin's dose_per_item of 3, against each device's max_dose, is what makes it bong-only. Strain files are read when the world opens: a change needs a restart, /reload does not re-read them.

• The press's speed follows world.machineSpeedMultiplier in the config.

Datapacks, Tags and Custom Strains have the details.
