Minecraft Underground Farming: Light Requirements & Setup

Many players build underground farms to maximize their space and create a controlled environment for growing crops and trees. One key factor in these setups is light. In Minecraft, it isn’t the sunlight itself that makes a difference, it’s the light level on the block where your plant is growing.

Light Levels in Minecraft

Minecraft uses a light level system ranging from 0 (complete darkness) to 15 (full brightness). The light level determines whether crops or tree saplings will progress through their growth stages. Key points include:

• Natural sunlight: Provides a light level of 15 on exposed blocks during the day.
• Artificial light sources: Items like torches, glowstone, lanterns, or sea lanterns provide sufficient light when placed appropriately.
• Torch specifics: A standard torch has a light level of 14 at its source, which is well above the minimum required for most plants.

Light Requirements for Crops

Crops such as wheat, carrots, potatoes, and beetroot require a minimum light level to grow efficiently. The details are:

• Minimum Light Level: 9 on the farmland block where the crop is planted.
• Why It Matters: Without at least level 9 light, the crop’s growth will either slow down significantly or stop completely.
• Underground Setup: When farming underground, ensure that every crop block receives at least a light level of 9 by placing torches or another light source nearby.

Example:
If you place a torch on a wall adjacent to your crop, the crop block will be lit to a level that meets (or exceeds) the minimum, ensuring that your wheat grows as it would outdoors.

Light Requirements for Tree Saplings

Tree saplings have similar light requirements to crops but also need adequate space for growth. The key points are:

• Minimum Light Level: Approximately 10 on the block where the sapling is planted. Some sources cite a minimum of 9, but providing a level of 10 is a safe bet.
• Headroom & Space:
  • Vertical Space: Most trees require at least 7 blocks of vertical space above the sapling for proper growth. Some tree types (e.g., jungle or large oak trees) might need even more room.
  • Horizontal Space: While a sapling can grow with adjacent blocks, providing more open space often results in a fuller tree with more wood.
• Underground Setup: When planning an underground tree farm, arrange your light sources (e.g., torches) so that the block where the sapling sits reaches at least light level 10. Also, ensure you have the required space above the sapling.

Example:
An underground tree farm might consist of rows of dirt with saplings and torches placed on nearby walls or in alternating patterns. This setup guarantees that each sapling receives the minimum light level while also having enough headroom to grow into a full tree.

Setting Up Your Underground Farm

Here are some practical tips for designing your underground farm:

1. Plan Your Layout:
   • For crops, ensure every farmland block is within 4 blocks of a water source and lit to at least level 9.
   • For trees, design your planting area so that each sapling has at least 7 blocks of free vertical space above it.
2. Light Placement:
   • Torches: Position torches so that the light spreads evenly across your growing area. Walls, ceilings, or even dedicated light blocks can be used.
   • Alternative Light Sources: Consider using glowstones or lanterns if you need a more even or brighter light spread.
3. Spacing Considerations:
   • Crops: A grid layout is often effective. For instance, placing torches between rows can cover several crop blocks.
   • Trees: Maintain a clear area around each sapling (typically a 5×5 or larger open space) to avoid any interference from adjacent blocks that might prevent proper growth.
4. Test and Adjust:
   • Monitor the growth of your plants after setting up the light. Adjust the placement if some crops or saplings do not seem to be receiving adequate light.

In Minecraft, whether you’re growing crops or tree saplings, the quality of light on the block is what matters—not necessarily natural sunlight. For underground farms:

• Crops need a minimum light level of 9.
• Tree Saplings require around 10 plus adequate space (at least 7 blocks of headroom) to grow properly.

Using torches or other artificial light sources to achieve these levels allows you to build productive underground farms, ensuring your plants thrive regardless of the absence of natural light.
