Unlock the Nursery at Level Four
The Nursery is the turning point from repeatedly replanting crops by hand to producing plants continuously. Reaching it quickly matters because plants feed important recipes such as rope, healing items, bandages, and fertilizer components.
For alchemy factory how to unlock nursery, the required milestone is reaching player level four. Once level four is available, open the research options and research the Nursery. It is not an item bought directly from the regular building menu before research.
Early progression is usually smoother when you avoid building a large manual farm. Use a few Seed Plots to produce what you need, earn experience through normal crafting and shop activity, then move into Nursery research as soon as level four is reached.
| Requirement | What to do | Why it matters |
|---|---|---|
| Player level | Reach level 4 | Nursery research becomes available |
| Research | Select and complete Nursery research | Adds the automated growing building |
| Building materials | Prepare 12 Iron Ingots and 6 Clay per Nursery | Needed for each placed Nursery |
| Crop seed | Buy or unlock a seed type | Determines which crop the Nursery grows |
| Fertilizer | Build a steady supply line | Keeps crop production running |
Do not confuse a Nursery with a Seed Plot. A Seed Plot is useful at the beginning, but it requires harvesting and planting again after every growth cycle. A Nursery holds its selected seed and produces crops as long as it receives fertilizer.
What to Do Before Level Four
You can make the Nursery unlock feel much faster by preparing its inputs while leveling. The most useful early crops are usually flax and sage. Flax supports several practical crafting chains, while sage is important because it can be converted into Plant Ash for fertilizer.
Start with a small number of Seed Plots rather than covering your factory with them. Each Seed Plot costs stone, accepts a seed packet, and can be harvested once its timer finishes. Replant the same crop after harvest until you have enough materials for your immediate production goals.
A sensible early-game routine is:
- Place one or two Seed Plots for flax if you need basic plant-based materials.
- Add sage production before researching the Nursery, even if you do not yet need much of it.
- Continue crafting, selling, and completing available work that advances your level.
- Save iron and clay instead of spending all of them on unnecessary expansion.
- Build only enough manual crop capacity to support your current recipes.
| Early resource | Best use before Nursery | Later Nursery role |
|---|---|---|
| Flax | Supports basic plant-material crafting | Reliable automated crop output |
| Sage | Can be burned into Plant Ash | Key ingredient source for fertilizer |
| Limestone | Hold or buy when possible | Becomes Quicklime Powder through processing |
| Iron Ingots | Save for construction | Each Nursery requires 12 |
| Clay | Save for construction | Each Nursery requires 6 |
The game’s early loop can feel slow because manual farming requires frequent attention. That is normal. Treat manual plots as a temporary bridge rather than a permanent factory design. The Nursery is designed to remove the replanting loop, but only after you establish enough production to feed it.
Research, Build, and Seed Your First Nursery
After reaching level four, research the Nursery, then open the build menu and place one where belts can reach it easily. Each Nursery costs 12 Iron Ingots and 6 Clay, so one working Nursery is more valuable than several unfinished crop lines.
Choose your first seed based on the bottleneck in your factory. Sage is often a strong first choice because fertilizer requires Plant Ash, and Plant Ash comes from processing plants. Flax is useful when your immediate production chain needs its outputs more urgently.
Once the Nursery is placed, interact with it and load the seed you want to grow. Unlike manual Seed Plots, the seed is not consumed each time a crop is produced. The continuing cost is fertilizer, not replacement seeds.
| Nursery action | Result | Common mistake |
|---|---|---|
| Research Nursery at level 4 | Unlocks the building | Looking for it before research |
| Place the Nursery | Creates an automated crop producer | Forgetting the iron and clay cost |
| Insert a seed | Sets the crop type | Assuming seeds must be constantly replaced |
| Deliver fertilizer | Starts repeat crop production | Supplying raw plants instead |
| Route output away | Sends crops to storage or crafting | Letting output clog the area |
Leave room around the building for belts, storage, or splitters. A compact layout is useful, but your first Nursery does not need to be a perfect blueprint. The priority is proving that the full chain works: seed loaded, fertilizer delivered, crop output collected.
If the machine appears inactive, check the fertilizer input first. The Nursery does not grow plants from clay, sand, or other old-material alternatives. Current production relies on fertilizer.
Make Fertilizer Before Expanding
Fertilizer is the real operating cost of automated farming. A Nursery can retain its seed, but it needs an ongoing fertilizer supply to keep producing. Building many Nurseries before stabilizing fertilizer usually creates a factory full of idle machines.
Basic fertilizer depends on two important materials: Quicklime Powder and Plant Ash. Plant Ash comes from burning plant matter, commonly sage, in a Crucible. Quicklime Powder requires a longer chain: process Limestone in a Stone Crusher, turn the result into Quicklime with a Crucible, then use a Grinder to make Quicklime Powder.
| Fertilizer component | Production path | Preparation tip |
|---|---|---|
| Plant Ash | Grow Sage → process in Crucible | Start sage production early |
| Quicklime Powder | Limestone → Stone Crusher → Crucible → Grinder | Set up limestone supply before scaling |
| Fertilizer | Combine its required components | Feed it directly into Nursery inputs |
| Advanced Fertilizer | Later upgraded fertilizer option | Use it when unlocked for larger builds |
This creates an intentional loop: crops help create fertilizer, and fertilizer helps grow more crops. It can seem awkward at first, but it becomes stable when you dedicate some crop output to ash production and send the rest to your desired recipes.
For a first setup, keep it simple:
- Grow sage manually or in one Nursery.
- Reserve part of the sage output for Plant Ash.
- Process limestone into Quicklime Powder.
- Assemble fertilizer and belt it toward the Nursery.
- Store excess fertilizer before adding more crop buildings.
Advanced fertilizer improves the experience later, especially for larger farms. Until then, avoid assuming one basic fertilizer belt can support an unlimited number of Nurseries. Watch whether fertilizer accumulates or runs dry, then adjust your production line.
You can also manage input slots carefully. Nurseries have multiple slots, and unrestricted delivery can fill more slots with fertilizer than your setup needs. Players sometimes reserve slots with single items or non-conveyor items to limit how much fertilizer is stored. This is optional; use it only after the core crop line is functioning.
FAQ
How do I unlock the Nursery in Alchemy Factory?
Reach level four, then research the Nursery. After research, build each Nursery with 12 Iron Ingots and 6 Clay, insert a seed, and provide fertilizer.
What is the fastest answer to alchemy factory how to unlock nursery?
Focus on normal early crafting and sales until level four, avoid overbuilding manual farms, then research the Nursery immediately. Prepare iron, clay, sage, and limestone while leveling so your first Nursery can run right away.
Does the Nursery consume seeds?
No. After you load a seed into a Nursery, it remains selected. The building needs fertilizer for continued crop production instead of consuming a new seed every cycle.
Why is my Nursery not producing crops?
Check whether it has fertilizer. A loaded seed alone is not enough. You also need an output route or storage space so produced crops do not create a blockage.
What should I grow in my first Nursery?
Sage is a practical option because it can become Plant Ash, which supports fertilizer production. Choose flax first instead if your current crafting chain needs flax-based materials more urgently.
