All possible sizes and some possible materials for the MultiFarm's main structure.

The MultiFarm is a multi-block structure added by Forestry, used to automate many forms of farming. These structures are larger and more complicated than the older Forestry farms, which the MultiFarm replaces. MultiFarms require a constant supply of Fertilizer, MJ, and water to run.

Building a MultiFarm[edit]

The MultiFarm is one of the largest multi-block structures in FTB. All versions of the MultiFarm are 4 blocks tall. It can be built in 3x3, 3x4, 4x4, and 5x5 variants, each of which provides increasingly large amounts of crop spaces for the farm to grow in. Future versions will also include a 4x5 variant. In addition to the structure itself, which must be composed of the component blocks, the farm also requires a surface to place its crops on which must be built out of any of the Base Materials.

The second row from the top must be composed of Farm Blocks. The rest of the structure may be made up of any of the component blocks. Unlike other multi block structures, even the interior of the MultiFarm needs to filled with Farm Blocks.

An example of a MultiFarm with the surface placed at the highest level.

Once the primary structure itself is built, the MultiFarm needs a surface to place the crops it grows on. This can be made out of any of the base materials. Once this is placed, and the MultiFarm is operational, it will place its farm in a diamond pattern on this surface. The surface can be placed level with any of the levels of the MultiFarm, or it can be placed one block below the bottom level, but it cannot be placed above the MultiFarm.

Multiple layers of these blocks may be placed if you are growing 1 or 2 block tall crops like wheat, potatoes, carrots, or netherwart.

Base Materials[edit]

All vanilla blocks used in the MultiFarm - both in the crafting recipes and the actual layout of the farm - can be any of the following blocks:

  • Stone Bricks
  • Chiseled Stone Bricks
  • Cracked Stone Bricks
  • Mossy Stone Bricks
  • Smooth Sandstone
  • Chiseled Sandstone
  • Bricks
  • Nether Bricks

The Farm Blocks will take on the appearance of whichever block is used to craft them. Using Stone Bricks will yield Farm Blocks that look like Farm Stone Bricks.

New Note: Farm Sizes As of forestry_1.7.10- farm sizes have been changed drastically. A 3x3x4 multi block structure now creates a 15x15 Farm and a 5x5x4 multi block structure now makes a 35x35 Farm. Like the note below, you may limit the size of the farm by simply not placing enough Base Material Blocks (i.e. stone bricks, etc.).

Note: Farm Sizes The representations above show the largest extent of the Farm for each setup. You can lay out smaller extents of farmland, but the Farm won't be as efficient.

You will also need to lay out the area for the farmland, using any of the Base Material blocks.

The farmland can be laid out at any level (comparative to the Farm's structure), this means that you can place the farmland directly below the Farm Structure, aligned with any level of its 4-tall structure, etc. You cannot lay the farmland directly on top of the Farm's structure, though.

Valid? Yes, for any of these. No, invalid setup.

The table above is a side representation of both valid and invalid setups, regarding where you can place your farmland. Although they represent 3×3 setups, the concept is the same for the remaining sizes.

Farm Configuration[edit]

To configure a farm to grow and harvest crops other than trees you need to make an Intricate Circuit Board in a Carpenter and one of each appropriate Electron Tube in the Thermionic Fabricator. The multifarm is broken up into four sections, each of which can be programmed independently by placing the appropriate electron tube in the correct location on the circuit board. From top to bottom the four slots on the Circuit Board will program the North, South, West, and East sections. The farm has two possible modes, Managed and Unmanaged. Managed farms will plant the substrate (dirt for example) and seeds/saplings for you automatically. Unmanaged farms do not, you must place the substrate and seeds by hand, although the farm will harvest the appropriate resources. Farms must be entirely one mode or the other, you cannot mix managed and unmanaged sections. You choose the mode in the Soldering Iron GUI, using the left and right arrows on the top before placing the tubes or circuit board.

The corner bricks on a multifarm are assigned to the respective east and west sides, making those sections considerably larger than the north and south sides, especially on the 3x5 farm.

As of the 3.5.0 Forestry patch, multifarm sides now have balanced areas. Each side has its respective square portion and also the angular corner portion that resides directly counter-clockwise to the section.

There are two overall types of farm that can be created: Managed and Manual. Both are created through using a Soldering Iron on an Intricate Circuit Board, and adding in electron tubes for the type of farm required.

Managed Farms[edit]

Managed Farms not only plant and harvest crops, but they will also set the necessary soil for the crops to grow.

By setting your Soldering Iron to Managed Farms, you can have the following:

Type Electron Tube Type Soil Water Fertilizer Germlings Harvest
Arboretum* Copper Dirt 10 mB 30 mU Saplings Wood, Saplings, Apples, Rubber
Peat Bog Tin Bog Earth 20 mB 10 mU None Peat, Dirt
Crop Farm Bronze Dirt 20 mB 10 mU Seeds Wheat, Barley
Vegetable Farm Iron Dirt 20 mB 10 mU Carrots, Potatoes Carrots, Potatoes
Infernal Farm Blazing Soulsand None 20 mU Netherwart Netherwart
Mushroom Farm Apatine Mycelium 80 mB 20 mU Mushrooms Large Mushrooms
  • Note that for the newer versions an Arboretum is made without any circuit in the GUI.

Manual Farms[edit]

Manual Farms, unlike Managed Farms, will not set the soil for the crops to grow or place the initial seeds or saplings, but it will replant and harvest the crops/trees in its operation radius.

By setting your Soldering Iron to Manual Farms, you can have the following:

Type Electron Tube Type Soil Water Fertilizer Germlings Harvest
Orchard Copper Dirt 40 mB 10 mU Trees (Grown) Any Fruit
Peat Bog Tin Bog Earth 20 mB 10 mU None Peat, Dirt
Crop Farm Bronze Dirt 20 mB 10 mU Seeds Wheat
Vegetable Farm Iron Dirt 20 mB 10 mU Carrots, Potatoes Carrots, Potatoes
Succulent Farm Golden Sand 1 mB 10 mU Cactus Cactus
Reed Farm Diamantine Dirt/Sand 20 mB 10 mU Sugar Cane Sugar Cane
Rubber Plantation Rubberised Dirt 5 mB 10 mU Rubber Saplings Sticky Resin
Gourd Farm Obsidian Dirt 40 mB 10 mU Pumpkin/Melon Seeds Pumpkins, Melons
Cocoa Farm Lapis Jungle Wood 20 mB 120 mU Cocoa Beans Cocoa Plants

Note that Rubber Plantations do NOT cut down or replant the trees. All it will do is harvest the Sticky Resin. Use an Arboretum (see Managed above) with Forestry rubber trees.

Farm Orientation[edit]

The order of the Electron Tubes on the Circuit Board determines the orientation for each section on the Farm. The orientation is as follows:

Farm Orientation

This orientation is important, because the size of the sections varies with the placing on the farm, especially in farm setups that are not square (for example, a 3×5 setup). The N, S, W and E represent, respectively, North, South, West and East.


After version for the simplest set up "Arboretum" put Dirt as a substrate, Humus does not work.

"Arboretum" Mode appears to recognize rubber trees only as regular trees. It will plant the saplings and chop them down but will not harvest any sticky resin. (good for collecting more saplings and rubber wood which can then be extracted into rubber, however, to gain the most amount of saplings, restrict the locations of where they're able to be planted for the most amount of leaves without crowding other trees too much, otherwise you'll run out of saplings)

You cannot attach an Item Tesseract to the bottom of the Farm Hatch, you first need to attach a pipe, and then the Tesseract. Tesseracts can be directly attached to the Farm Valve and Farm Gearbox though.

There is a option in the config files to make farms generate as a square pattern rather than as the default diamond shape. The width of the square is the same as the diameter of the diamond pattern for each farm size, essentially filling in the corners of the diamond to make a square. This means that farms have approximately 70% more area.

Note: RedPower 2 Tubes behave differently than Buildcraft Pipes! This is not a bug.

Fertilizer is added from the west side, soil from the north, and seeds/saplings from the top. Items are extracted from the bottom.

Will display the "No Farmland" error if there is a Farm Control block installed and is also powered by redstone during initialization.
