Rust: Complete Farming Guide

Updated June 2026 - verified against the official Facepunch Rust wiki and the current Farming 2.0 system.

Farming in Rust provides sustainable food sources, cloth production, and valuable resources for crafting. Understanding crop genetics, irrigation, lighting, and soil quality is essential for maximizing yields. This guide covers everything from basic hemp farming to the gene-selection and cloning workflow used to build perfect plants.

How Plant Growth Actually Works

Every plant tracks several conditions independently, and its real growth speed is capped by whichever one is worst. Get five conditions perfect and one terrible, and the plant grows at the speed of that terrible stat. The four that matter most:

• Light: Light comes only from the sun and from ceiling lights. The sun lights a plant for roughly half the day, so an outdoor plant grows at about half speed compared with a plant under a permanent ceiling light. One ceiling light directly above each planter keeps light at 100% around the clock.
• Water saturation: A planter holds up to 9,000 ml of water. Keep saturation high (roughly 6,000-8,000 ml) with a sprinkler so the water stat never throttles growth. Genes change how fast a plant drinks (see Water below).
• Soil quality: Planters start at a decent base and climb toward 100% as you add fertilizer. Higher soil quality directly raises yield and health.
• Temperature: Plants prefer comfortable temperatures. An enclosed, heated grow room keeps temperature in range so it is never the limiting factor.

Farmable Crops

Crop	Primary Use	Growth Time	Yield
Hemp	Cloth production	40-60 minutes	10-30 cloth per plant
Corn	Food (high calories)	60-90 minutes	3-8 corn per plant
Pumpkin	Food (hydration + calories)	60-90 minutes	2-6 pumpkins per plant
Potato	Food (balanced nutrition)	50-80 minutes	4-10 potatoes per plant
Berry (5 colours)	Light food + Tea brewing	Fast - among the quickest crops	Several berries per bush

Getting Started with Farming

Essential Tools & Materials

Planter Types

Rust has two craftable planter boxes. Both cost wood plus tarp (not metal fragments), and plants in a planter grow about twice as fast as plants placed on bare ground.

Planter	Capacity	Craft Cost	Best For
Small Planter Box	3 plants	100 Wood + 1 Tarp	Starter farms, single clones, tight rooms
Large Planter Box	9 plants	200 Wood + 2 Tarp	Maximum yield - fits a 2x2 grow room cleanly

Crop Genetics System

The 5 Genes and 6 Slots

This is the single most misunderstood part of Rust farming. Every plant has 6 gene slots, and each slot is filled by one of 5 gene types. A plant might read G G Y Y H W - that is six slots, drawing on the five types below. Per the official wiki, only W and X are bad genes; you want as few of those as possible.

Gene	What it does	Good or bad?
Growth (G)	Speeds up maturation - more G slots = faster harvests	Good - want more
Yield (Y)	Increases resources per harvest (cloth/food)	Good - want more
Hardiness (H)	Plant tolerates poorer water, light and temperature	Good - useful filler
Water (W)	Raises water consumption - drinks the planter dry faster	Bad - minimise
Empty / Wildcard (X)	A null slot that does nothing useful and dilutes good genes	Bad - breed out

A plant's quality is just how many of its six slots are the genes you want. GGGYYY (three Growth, three Yield) is the classic "god" hemp clone - fast and high-yield. GGYYYY is a popular variant: slightly less growth, even more yield, and easy to keep cloning.

How Crossbreeding Works

To improve genes you grow plants next to each other so good slots can override bad ones. Crossbreeding is resolved per slot (column by column), comparing each plant against its neighbours:

• Adjacency matters. A plant in the centre of a planter touches every neighbour, so it receives the most genetic influence. A corner plant only touches the three plants beside it.
• Good genes are out-weighted by bad ones one-for-one. Roughly speaking the desirable genes (G/Y/H) carry less weight than W in a head-to-head, so you need a majority of good genes in a slot to reliably overwrite a bad one. The practical rule: surround a target plant with strong donors so each slot is won by the gene you want.
• Set up the centre on purpose. If no two donor plants share the same bad gene in the same slot, the centre plant is forced to inherit good genes in every slot.

Gene-Selection and Cloning Workflow

This is the repeatable loop that turns random wild seeds into perfect plants:

1. Gather starting genes. Plant wild seeds (hemp, berries, etc.). Hold a Tea or look at the planted seed to read its gene string.
2. Cull the junk. Discard anything heavy on W and X. Keep your best two or three plants as donors.
3. Crossbreed up. Arrange donors around a central target so each slot is won by G, Y or H. Let them reach the Ripe stage, then read the centre plant's new genes.
4. Clone the winner. When you finally hit a great string such as GGGYYY, take a clone (only available at Ripe). Clones are genetically identical copies - no RNG.
5. Mass-produce from clones. Fill your planters entirely with clones of that one perfect plant. From here you never crossbreed again; you just re-clone the best plant each cycle to keep the line alive.

Irrigation Systems

A Large planter holds up to 9,000 ml of water. Keep saturation high (roughly 6,000-8,000 ml) so water never becomes the stat that throttles growth. The fewer W (Water Intake) genes your plants carry, the slower they drain.

Water Sources

• Manual Watering: Pour a Water Jug or Bucket straight into the planter - fine for one or two plants, tedious at scale.
• Water Catchers: Collect rainwater automatically. Small and Large Water Catchers feed a tank you can pipe to sprinklers.
• Water Pump: Sits in a river, lake or ocean and pushes a steady supply uphill - the reliable source for a permanent farm.
• Sprinkler: The automated waterer. It needs electricity and a water feed, and it keeps every planter underneath it topped up.

Sprinkler Setup

The Sprinkler is the only powered waterer in Rust - there is no "advanced" tier. Run water in and power in, and it saturates the planters around it. The standard chain for an off-grid farm:

Water Pump / Catcher --> Water Storage --> Sprinkler --> Planters
Solar Panel --> Battery --> Sprinkler (power)

• One sprinkler per Large planter is the clean layout - it keeps all nine plants saturated.
• Battery buffer: a Large Rechargeable Battery lets solar power the sprinkler through the night so saturation never crashes while you sleep.
• Mount it above the planter so the spray lands on the soil rather than a wall.

Fertilizer & Soil Quality

Rust has a single Fertilizer item - there is no basic/advanced tier and no sulfur recipe. Fertilizer raises a planter's soil quality toward 100%, which in turn lifts plant health and yield. You make it, you do not craft it from cloth.

Where Fertilizer Comes From

Applying Fertilizer

• Add it to the planter, not the plant. Place Fertilizer into the planter's inventory and it is consumed over time to keep soil quality high.
• Keep soil at 100%. Soil quality is one of the stats that caps overall growth - a half-empty fertilizer slot quietly slows every plant in the box.
• Prioritise your money planters. If fertilizer is scarce early, keep your hemp and your god-clone seed plant topped up first.

When to Harvest Hemp in Rust

Hemp Growth Stages

Stage	Visual cue	What you get if you harvest now
Seedling	Tiny sprout, dark green	Nothing useful - destroys the plant.
Sapling	Knee-high, no flowers	Nothing useful - destroys the plant.
Cross-breeding	Reaching surrounding plants	Stage where neighbouring plants influence genetics. Don't harvest yet.
Mature	Full size, no flowers	Cloth at 50-70% of the maxed yield. No clones available.
Ripe (harvest now)	Bright yellow flowers, "Ripe" label	Maximum cloth + clones available.
Dying	Browning leaves, drooping	Yield drops every minute - pick immediately or lose the plant.
Dead	Brown husk	Plant is gone, loot is minimal.

How to Tell It's Ripe

• Look at the flowers. Mature hemp has none. Ripe hemp is unmistakably yellow and visibly "lit up" compared to neighbours.
• Read the loot prompt. Looking at the plant shows "Ripe" - that's the cue.
• Take a clone first. Right-click and choose Clone before harvesting if the plant has good genes - clones are only available at Ripe and they preserve the genetics perfectly.
• Harvest the same day you see Ripe. Plants only stay Ripe for a short window before sliding into Dying, where yield falls fast.

Hemp Farming (Cloth Production)

Why Farm Hemp?

• Cloth Demand: Essential for clothing, sleeping bags, and bandages
• High Yield: Optimized hemp plants produce 30+ cloth per harvest
• Fast Growth: With good genetics, harvest every 40 minutes
• Sustainability: Never run out of cloth for crafting

Optimal Hemp Farm Setup

For maximum cloth production:

1. Planters: a 2x2 room of 4 Large Planters (36 hemp plants).
2. Irrigation: one Sprinkler per planter, fed by a Water Pump or Catcher.
3. Lighting: one Ceiling Light per planter, on 24/7 for double-speed growth.
4. Genetics: fill every planter with clones of one GGGYYY (or GGYYYY) hemp plant.
5. Fertilizer: keep each planter's Fertilizer slot topped up from a Composter to hold soil at 100%.
6. Power: solar plus a Large Rechargeable Battery so lights and sprinklers run overnight.

Hemp Genetics Priority

You are not chasing a percentage - you are deciding what fills each of the six slots. The ideal hemp clone is all good genes, no W and no X:

Gene	How many slots	Why
Growth (G)	3 slots	Cuts the grow time so you harvest more often
Yield (Y)	3 slots	More cloth per plant - this is the cloth multiplier
Hardiness (H)	0-1 slots (filler)	Useful only if you cannot keep conditions perfect; otherwise spend the slot on G or Y
Water (W) / Empty (X)	0 slots	Both are bad - breed them out entirely

So the target string is GGGYYY for the fastest high-yield hemp, or GGYYYY if you would rather trade a little speed for even more cloth and an easier clone line.

Food Farming Strategies

Pumpkin Farming (Best Early Food Source)

Pumpkins are the go-to survival crop because they restore both hunger and thirst, so a pumpkin patch removes most of your food and water worries:

• Restores: meaningful calories and hydration from a single eat - the only common crop that covers both well.
• Yield: several pumpkins per plant, scaling up with Yield genes and 100% soil quality.
• Best use: plant pumpkins from wild seeds early-game; they grow fine outdoors and need no breeding to be useful.

Corn & Potato Farming (Hunger)

Corn and potatoes are pure calorie crops - they fill hunger but give little hydration, so pair them with pumpkins or a water source:

• Corn: high calories per piece; a reliable staple once you have a stable food loop.
• Potato: balanced, plentiful calories; potatoes can be planted directly and store well.
• Cooking: cooking food in a furnace, campfire or oven raises its calorie value and reduces the chance of food poisoning.

Berry Farming (Tea & Teas)

Berries are light food, but their real value is Tea brewing at a Mixing Table:

• Five berry colours (red, blue, green, yellow, white) each feed into different Tea recipes.
• Teas matter for farming itself - some boost crop yield or your own gathering, ore and scrap output, so a small berry plot pays for itself.
• Fast and easy: berries are among the quicker crops and need no special setup to get going.

Balanced Diet Farm

Recommended crop distribution for self-sufficiency:

Crop	Planters	Purpose
Pumpkin	2	Primary food + hydration
Corn	1	High-calorie backup
Potato	1	Balanced nutrition
Hemp	4	Cloth production

Advanced Farming Techniques

Why Indoor Beats Outdoor: Ceiling Lights

This is the biggest single upgrade you can make. Outdoors, the sun only lights plants for about half the day, so growth runs at roughly half speed. A Ceiling Light placed directly above a planter and left on supplies light 24/7 - plants under a ceiling light grow about twice as fast as sun-lit plants, on top of the 2x bonus a planter already gives over bare ground.

• One ceiling light per Large planter, mounted on the ceiling tile directly above it.
• Never go dark. If light hits zero, plant health falls to zero and growth stops entirely - keep the lights powered around the clock.
• Add a heater to hold temperature in range, removing the last stat that can throttle growth in an enclosed room.

Powering an Indoor Farm

A self-contained electric farm draws on a few components:

• Solar Panel + Large Rechargeable Battery: daytime solar charges the battery, the battery runs lights and sprinklers overnight.
• Sprinkler: one per Large planter, fed by a Water Pump or Catcher.
• Ceiling Light + Heater: one set per planter for light and temperature.

Rooftop Farming

Maximize space by farming on your base roof:

• Advantages: Hard to raid, good sunlight, space-efficient
• Disadvantages: Exposed to weather, requires strong roof support
• Setup: Place planters on flat roof sections, add sprinklers

Common Farming Mistakes

Mistake	Why It's Bad	How to Fix
Confusing 5 genes with 6 slots	You chase a non-existent "perfect" gene instead of stacking good slots	Remember: 6 slots, each one of 5 gene types. Maximise G/Y/H slots, minimise W and X
Ignoring genetics	Low yields and slow growth from random wild seeds	Crossbreed up, then clone the winner and farm only clones
Farming in sunlight only	Roughly half-speed growth - the sun lights plants half the day	Build an enclosed room with a ceiling light over each planter, on 24/7
Letting water or fertilizer run out	Overall growth is capped at the lowest stat, so one empty resource stalls everything	Keep a sprinkler running and the planter's Fertilizer slot stocked from a Composter
Crossbreeding mixed crops together	A hemp plant beside berries pollutes both gene pools	Keep one crop type per planter while breeding; only mix identical clones

Farming Economics

Cloth Value

Optimized hemp farm produces 1,000+ cloth per hour:

• Sleeping Bags: 30 cloth each (33 bags per harvest)
• Bandages: 4 cloth each (250 bandages per harvest)
• Clothing: 50-100 cloth per set
• Trade Value: Cloth is highly valuable for trading with other players

Food Self-Sufficiency

A balanced farm eliminates the need to hunt or scavenge:

• Daily Calories: 500-800 calories needed per player
• Farm Output: 2,000+ calories per harvest cycle
• Surplus: Trade excess food for scrap or resources
