Growth and yield are not the same thing
Two separate systems share the same greenhouse. Conditions and compost only change how fast a crop finishes; the module, your Farming skill and greenhouse upgrades change how much you harvest.
Growth speed
Everything that changes when a crop finishes.
- Module growth bonus
- Compost
- Greenhouse upgrade
- Growing conditions
- Farming skill
- Total growth bonus
- Actual growth rate
Yield
Everything that changes how much you harvest.

Which factors change growth and which change yield

Why is my greenhouse slow?
Your current setup is checked against the growth formula. Each line shows the growth bonus you are leaving unused and what would change it.
Biggest bottlenecks in your current setup
- 1. Module+20% growth available
A module with a higher growth bonus is compatible with this crop but is not equipped.
Fix this first
Additional module cost: 20,000
- 2. Greenhouse upgrade+10% growth available
The upgrade that adds growth speed is not part of this setup.
- 3. Farming skill+5% growth available
A higher Farming progression adds growth speed and yield.
Largest performance increase

Ranked by the growth bonus it can restore, not by price. A tier change also costs money, so check the module price before buying.

Temperature, humidity and light
Every greenhouse product has its own ideal temperature, humidity and light. The closer the current values are to that ideal, the more growth speed the environment adds.

Choose the right farming module
27 farming modules exist: 9 product families, each sold in Tier C, Tier B and Tier A. The tier sets the production bonus, but the required Farming level does not follow the tier.

Required Farming level by family and tier

|---|---|---|---|
| Cereals | Level 1 | Level 7 | Level 14 |
| Dairy | Level 1 | Level 7 | Level 14 |
| Fruit | Level 1 | Level 7 | Level 14 |

| Mushrooms | Level 2 | Level 7 | Level 14 |
| Roots | Level 1 | Level 7 | Level 14 |
Requirements are module-specific, so Tier C is not a single level. Herbs unlock their Tier C and Tier B modules later than Cereals, and Hydro unlocks Tier C before Tier B.
Levels come from the game's own Farming progression table, not from the module tier. The number shown is the Farming level a player sees for that progression row.
Will this module grow it?
Compatibility is an exact module-to-plant list, not a family rule. A higher tier is not automatically compatible with every product of a lower tier.
This module is listed as compatible with Corn in the canonical data.
Cereals — Tier B
What does Farming skill actually improve?
Farming progression is not only about experience. Each progression row adds yield and growth bonuses and unlocks more of the greenhouse.

- Condition controls
- Unlocked
- Upgrade capability
- Not yet
The upgrade column only shows when upgrade-related capability becomes available in the progression data. It does not prove automatic harvesting, replanting or a fully automatic greenhouse.

What does compost do?
Compost is a growth speed effect with no direct yield effect. It finishes the production cycle faster; it does not increase the number of items harvested in the canonical yield formula.
Growth speed
+15%
Direct yield bonus
0%
Compost answers "how do I finish faster?". If you want more items per harvest, compost is the wrong lever — use the module yield bonus or your Farming skill instead.
Growth formula
Growth speed is additive. Every source is added into one percentage, which is then applied to the crop's base growth rate.
Canonical formula
max(-100, moduleGrowthSpeedBonus + (hasCompost ? 15 : 0) + sum(upgradeGrowthSpeedBonus) + conditionsGrowthSpeedBonus + farmingLevelGrowthSpeedBonus)BaseGrowthRate * (1 + GrowthBonusPct / 100)1 / (growthDurationHours * 3600)Worked example from your setup
Base growth duration for Corn: 16.
Where the total comes from
Growth rate: 1.5× base
Effective cycle: 16h 0m → 10h 40m
A +50% growth bonus does not remove 50% of the time. It multiplies the growth rate by 1.5, so the crop finishes in about 66.7% of the base duration.
Yield formula
Yield is the harvest amount and it rounds to whole items. No growth-only factor appears in this formula.
Canonical formula
max(-100, moduleYieldBonus + sum(upgradeYieldBonus) + farmingLevelYieldBonus)baseYield + RoundToInt(baseYield * YieldBonusPct / 100)Worked example from your setup
Base yield: 10
Where the total comes from
Harvest amount: 11
The result is rounded to whole items, so 10 base yield with a 5 bonus becomes 11 instead of 10.5.
Compare greenhouse upgrades
Two greenhouse upgrades exist in the current data. Compare them by their actual effect rather than by an internal name.
Game effect

You want more items from every harvest.
Game effect

"When it may help" is site advice, not a game rule. The game effect above is the fixed part.
Effects come from the upgrade effect fields. Internal asset names are not shown because they can contradict the real effect.

Greenhouse questions players ask
Short answers to the confusions that bring players to this page.
Does compost increase yield?
No. Compost adds a flat +15% growth speed and contributes nothing to the yield formula, so it cannot change how many items you harvest.
Why is my greenhouse growing slowly?
Check the three condition axes first, then the module tier, then compost, then your Farming progression. The diagnostic above ranks them by the growth bonus each one can still restore.
Do temperature, humidity and light increase yield?
No. Conditions are a growth speed source only, worth up to +20% at the crop's ideal values. They never appear in the yield formula.
Is Tier A always the best module?
Tier A has the highest production bonus, but it also has the highest price, and the required Farming level is module-specific. If you only need one harvest, a cheaper tier can be the better purchase.
Why can't I plant a product in a module of the same family?
Compatibility is stored per module, not per family. A higher tier does not automatically inherit every product of a lower tier, so check the exact module before buying it.
What does the Farming level give the greenhouse?
Each progression row adds yield and growth bonuses and unlocks more of the greenhouse. The progression table above shows all of them.
Is +75% growth speed the same as 75% less time?
No. The bonus multiplies the growth rate, so +75% means a 1.75× rate and roughly 57% of the original duration, not a 75% reduction.
Can this page tell me how long my current crop still needs?
No. A static page cannot read your save, so it never claims a live greenhouse state. Enter your values manually, or wait for the save-based optimizer mode.
