If there is one secret to dominating the late-game economy of Plema Crafts’ hit automation sim, it is understanding how to weaponize your own overproduction. You need a definitive Void Harvesting guide F.A.R.M.S. players can rely on to scale their factories without bottlenecking their logistics networks. Void Harvesting in F.A.R.M.S.: Chill Factory is a late-game, tower-defense-style mechanic where you convert surplus factory materials into rare resources. By placing a Void Beacon to attract entities and supplying Void Turrets with ammunition via the game's intuitive Link System, you can purify the Void to farm exclusive endgame materials without ever risking your factory's destruction.
Since the game's full launch on Steam in May 2026, the community has quickly realized that reaching the end of the Tech Tree requires massive amounts of rare resources. You cannot simply idle your way to victory; you must actively manage your surplus. This guide breaks down the optimal strategies, the exact math behind ammunition scaling, and the logistical layouts required to turn your peaceful factory into an impenetrable, resource-generating fortress.
The Core Mechanics: A Void Harvesting Guide F.A.R.M.S.
Unlike traditional factory builders that punish you with base-destroying alien swarms, F.A.R.M.S.: Chill Factory keeps true to its name. Void entities will not tear down your conveyor belts, smash your Storage units, or halt your production lines. Instead, Void Harvesting is an opt-in economic engine designed specifically to solve the classic factory-game problem of overproduction.
You trigger the mechanic by placing a Void Beacon, which draws entities into a centralized kill zone. Your Void Turrets then consume your surplus manufactured goods as ammunition to "purify" these entities. Whether you are overproducing basic Iron Ingots, complex automobile parts, or even fresh Sushi, you can route that excess directly into the maws of your turrets.
Once purified, the Void drops rare resources. These materials are the lifeblood of late-game Tech Tree progression, allowing you to unlock higher-tier conveyor speeds, the Transport Accelerator, and advanced system features. Instead of letting your belts back up with thousands of unused construction materials and forcing your machines to idle, you maintain a continuous, high-efficiency flow that feeds your defensive perimeter.
Setting Up Your First Defense: Void Harvesting Guide F.A.R.M.S.
Building a functional defense requires mastering the game's unique logistics tools. The Link System allows for free-form, drag-and-drop connections between machine ports, including diagonal routing. When setting up your Void Turrets, position them in a tight perimeter around the Void Beacon to maximize overlapping fields of fire. Use Relays to keep your supply lines clean.

Because your turrets will chew through ammunition at an astonishing rate, you cannot afford spaghetti-belt bottlenecks. Route your surplus lines neatly around existing machines using Relays, ensuring a direct, uninterrupted flow of items to the turrets' input ports. Early in your Void Harvesting career, you might be tempted to hook up a single Storage container to a turret and call it a day. However, as the Void entities scale in health, a single line of basic materials will not output enough damage to purify them before they despawn or reset.
To ensure your turrets never run dry, utilize the Storage machine's output ON/OFF controls and item-type locks. By locking specific slots and managing the output flow, you can create a buffer system. When your primary Delivery Station lines are full, the overflow automatically redirects to your Void Turrets. This guarantees that your factory is always generating profit while simultaneously funding your defense grid.
The Meta Strategy: Packed Ammo in this Void Harvesting Guide F.A.R.M.S.
If there is one secret to out-scaling the endgame, it lies in the Packer machine. Introduced alongside the full release and heavily buffed in Patch 1.1.29, the Packer is the undisputed king of efficiency. A packed item delivered to a Void Turret counts as 10 items, increasing the turret's damage output by a massive 10x multiplier. Firing raw Iron Ingots is a waste; firing packed crates turns your turrets into artillery.

Prior to Patch 1.1.29, players struggled with ammunition density. A turret firing single items often couldn't output enough damage per second (DPS) to handle late-game Void waves, leading to wasted ammo and lost rare resources. The developers recognized this bottleneck and adjusted the scaling. Now, the math is undeniable: a single Link delivering packed items is mathematically equivalent to ten separate Links delivering raw materials.
This drastically reduces the number of Links and Relays you need to sustain a high-damage perimeter. It frees up visual space on a screen that might already be rendering tens of thousands of items, reducing visual clutter and making your factory floor infinitely easier to read. If you are not using the Packer to supply your Void Turrets, you are severely handicapping your resource generation.
Packer Logistics and the AUX Input Port
Understanding that packed ammo is the meta is only half the battle; setting up the logistics to automate it requires precision. The Packer is not a simple pass-through machine. It requires a secondary resource to function, and failing to provide it is the most common mistake new players make.
To operate the Packer machine, you must supply Cardboard specifically to the light blue AUX Input Port. Once properly fed, it generates 10-item bundles that can be routed directly to your defensive perimeter. This drastically reduces the number of connections needed, freeing up visual space on a screen that might already be rendering tens of thousands of items. Data modeling of late-game bases shows that relying on standard ammunition limits your throughput efficiency to roughly 10%, whereas routing packed ammo handles 90% of your defensive output requirements.

Setting up a dedicated Cardboard manufacturing line is now a mandatory step before you even place your Void Beacon. Route your Cardboard into a central Storage hub, and use Relays to distribute it to the light blue AUX Input Ports of multiple Packer machines. Once the Packers are outputting their 10-item bundles, you can safely connect them to your Void Turrets.
Be mindful of your machine upgrades. While the Crusher and Shaper machines had their output interval warning badges adjusted to reduce UI clutter, you still need to ensure your Packers are upgraded enough to keep pace with your turrets' firing rate. A starved turret is a useless turret.
Maximizing Delivery Station Profits and Rare Resources
Harvesting the Void is only the beginning; routing the spoils back into your economy is where the true mastery of F.A.R.M.S.: Chill Factory shines. The rare resources dropped by purified entities must be collected and fed back into your primary logistics network to fund further Tech Tree research.
You can route these materials into specialized manufacturing chains or send them directly to the Delivery Station to generate massive capital. Keep in mind that the Delivery Station evaluates items based on Yield, Grade, and Precision. Category-based trade bonuses also apply, and selling packed items yields significantly higher returns.
If you find yourself with an excess of packed items that your turrets do not need, do not let them sit idle. Route them through an Unpacker to restore them to their original state for specific crafting recipes, or send the packed bundles directly to the Delivery Station to capitalize on their multiplied value. Just be careful with the Buff Cleaner machine—prior to recent hotfixes, it inadvertently removed the packed state from processed items, ruining their value. Always ensure your logistics flow bypasses unnecessary cleaners when dealing with high-value packed goods.
Balancing how much rare material you reinvest into the Tech Tree versus how much standard surplus you sell for immediate capital is the core loop of the endgame. The most successful factories operate on a razor's edge, perfectly dividing their output between market profits and Void purification.
Frequently Asked Questions (Void Harvesting Guide F.A.R.M.S.)
Do Void entities destroy my factory? No. F.A.R.M.S.: Chill Factory is a relaxed automation sim by design. Void entities will not damage your machines, destroy your Links, or halt your production. The tower-defense aspect is purely an economic conversion tool to turn surplus items into rare resources.
How do I increase my Void Turret damage? The most effective way to increase damage is by using the Packer machine. By supplying Cardboard to the Packer's light blue AUX Input Port, you can bundle 10 identical items together. Feeding these packed bundles to a Void Turret increases its damage by a 10x multiplier, making it the most efficient way to clear waves.
Why isn't my Packer machine working? A common mistake is failing to supply the necessary secondary material. The Packer requires Cardboard to function. You must route Cardboard specifically into the light blue AUX Input Port on the machine; feeding it into a standard input port will not trigger the packing process.
Can I use any item as ammunition? Yes. Void Turrets will accept almost any manufactured item as ammunition. Whether you are overproducing basic construction materials, Cake made from grown wheat, or advanced electronics, you can route the excess into your defense grid to keep your factory lines moving.
What do I do with the rare resources? Rare resources dropped by purified Void entities are required to unlock the final tiers of the Tech Tree. They can also be routed to the Delivery Station for high-profit sales, provided you manage your Yield, Grade, and Precision metrics effectively.
