Farming Guide: Mining, Oil & Orbital Collectors

Farming in Dyson Sphere Program means acquiring planetary and cosmic natural resources reliably and at scale — from early-game coal and stone to late-game hydrogen/deuterium via Orbital Collectors. Proper farming underpins stable power, fuel, and high-tier manufacturing (matrices, graphene, Casimir crystals, fuel rods). This guide explains the main farming methods, what they produce, and practical tips for building sustainable supply chains.

Overview of farming methods

  • Manual harvesting: Icarus can pick up rocks, trees (Logs), Plant Fuel, Organic Crystals and rare drops by walking the surface. Use for early fuel, occasional Organic Crystal, and rare items; not suitable for continuous supply.
  • Mining Machines and Advanced Mining Machines: the primary automated method for solid veins (iron, copper, coal, silicon ore, rare crystals, etc.). Place them over veins to extract automatically; extraction rate scales with how many veins the machine covers and with Veins Utilization research.
  • Oil Extractors and Water Pumps: extract Crude Oil from seeps and Water from seas; both are infinite if the planet has the resource but oil seeps have a half-life that reduces output toward a minimum unless supplemented by Veins Utilization.
  • Orbital Collector (for Giants): place on the equator of Gas Giants (or Ice Giants) to collect Hydrogen/Deuterium or Hydrogen/Fire Ice continuously — effectively the main late-game farming method for hydrogen isotopes and Fire Ice.
  • Rare-vein harvesting and planetary choice: many high-demand items (Spiniform Stalagmite Crystal, Unipolar Magnet, Kimberlite, Fire Ice) appear as rare veins or on specific planet types. Securing planets with rich deposits simplifies production of graphene, carbon nanotubes, and other late-game components.

Veins Utilization — the central farming upgrade

  • Veins Utilization increases base gathering speed by a flat +10% per level (multiplicative on base) and reduces vein consumption (the rate veins are depleted) via a compounding reduction (about -6% of the current consumption per research). It also increases certain Dark Fog drop rates.
  • Apply Veins Utilization heavily for long-term farming: it boosts outputs from Mining Machines, Oil Extractors, Water Pumps, and Orbital Collectors and greatly lowers vein depletion, allowing longer-lasting finite veins and rarer resource exploitation.

Mining Machines vs Advanced Mining Machines

  • Mining Machine (base): harvests each covered vein at a base rate (displayed as 30/min per vein on many sources). Place to cover as many veins as practical; overlapping coverage increases consumption proportionally.
  • Advanced Mining Machine: higher extraction rate and much larger coverage (approximately 11×9 grid). It has adjustable mining speed (100–300%) and corresponding power that scales roughly with the square of speed. It features internal storage (up to 5000, extendable by Logistics Carrier Capacity) and integrated logistics (accepts drones, multiple conveyor ports). Use Advanced Mining Machines for late-game, large veins, and when you want built-in logistics.

Practical tips:

  • Multiple mining machines can cover and accelerate the same vein, but that increases vein consumption (unless mitigated by Veins Utilization).
  • For large veins use Advanced Mining Machines or multiple machines to fully cover the deposit.

Oil Extractors, Water Pumps, and Crude Oil

  • Oil Extractors harvest Crude Oil seeps. The extractor’s displayed base rate is reduced over time according to a half-life (default 12 continuous hours) unless you research Veins Utilization which increases production and reduces depletion.
  • Crude Oil refines into Refined Oil and Hydrogen via Oil Refinery (Plasma Refining). This chain is central for graphene and organic crystal production early–mid game.
  • Water Pumps on watery planets provide effectively infinite Water for Sulfuric Acid and other processes.

Orbital Collectors and Giant planets

  • Orbital Collectors must be placed on the equator of a Giant (Gas or Ice). They gather concurrently every resource type available from that Giant.
  • Base Gathering speed of an Orbital Collector is 8×. This multiplies with Veins Utilization boosts (e.g., Veins Lv2 gives 8× * 120% = 9.6× displayed).
  • Important: part of the collected material is consumed immediately to fuel the Orbital Collector’s continuous power draw (30.0 MW). The actual usable output is reduced because fuel use is drawn proportionally from gathered resources and weighted by each resource’s energy value. The true production multiplier can be calculated from veins boost, base 8×, and the collector’s power relative to the total potential burnable heat from the raw gathered resource mix.
  • Orbital Collectors are extremely effective infinite sources for Hydrogen, Deuterium, and Fire Ice; they are the recommended method for large Hydrogen and Deuterium supply required by advanced matrices and fuel rod production.

Practical placement constraints:

  • Orbital Collectors can only be built on equatorial tiles. They must be spaced at least 10 grid cells apart longitudinally (about 9° longitude), limiting the maximum per Giant (often cited max ~40 per giant).
  • Each Collector begins producing immediately; multiple Collectors on the same Giant multiply global harvest proportionally — individual Collector yields are unaffected by the presence of others.

Hydrogen, Deuterium, and Fuel Rod chains

  • Hydrogen harvested from Giants, refined oil, or produced via cracking is a critical input for many late-game items: Casimir Crystals, Quantum Chips, Gravity Matrix chains, and fuel rods.
  • Deuterium (a hydrogen isotope) is used for Deuteron Fuel Rods, Strange Matter, and Plasma Capsules. Deuterium demand is high for Strange Matter and fuel rods used in rockets and power generation. Meeting Deuterium needs typically requires Fractionators (distillation) and/or selecting Giants with higher Deuterium yields plus Orbital Collectors.
  • Hydrogen-based fuel rods (Hydrogen fuel rod, Deuteron Fuel Rod) have high energy density and are useful both for the Mech and for power plants. Deuteron Fuel Rods burn for a fixed time in fusion plants and are dense energy sources for outposts and rockets.

Design notes:

  • Casimir Crystals and other late high-tier components consume hydrogen at enormous rates (e.g., Casimir Crystal recipes include many hydrogen units). If you plan large-scale Casimir or Gravity Matrix production, set up many Orbital Collectors on suitable Giants or build fractionation infrastructure.
  • Consider locating Deuterium-sensitive production and fractionators near Giants’ satellites/stations to minimize logistics latency.

Graphene, Carbon Nanotubes, and Fire Ice

  • Graphene is a central late-game material needed for Solar Sails, rockets, Information and Gravity Matrices, and carbon nanotubes. It is typically produced from Coal and Crude Oil early/mid game but becomes far easier if you secure Fire Ice (Methane Hydrate) via Ice Giants or Fire Ice veins.
  • Fire Ice harvested from Ice Giants or certain planets is an excellent source for graphene raw materials and yields Hydrogen as a byproduct that can be routed into hydrogen-hungry recipes.
  • Carbon Nanotubes are produced from Graphene and Titanium; Spiniform Stalagmite Crystal (a rare deposit) can produce Carbon Nanotubes in one step when available, greatly simplifying the chain.

Strategy:

  • If your starting system lacks Fire Ice or Spiniform deposits, target systems with Glacieon/Ice Giant/Fire Ice to scale graphene and carbon nanotube production.
  • Where Fire Ice is available, use it to reduce the complexity of graphene lines and to utilize the byproduct hydrogen.

Rare resources and planning (Unipolar Magnet, Kimberlite, Spiniform Crystal, Grating Crystal)

  • Rare resources like Unipolar Magnet, Kimberlite Ore, Spiniform Stalagmite Crystal, and Grating Crystal appear as limited vein deposits or as planet-specific yields. They are crucial for particular advanced parts (Particle Containers, Diamonds, Carbon Nanotubes, Photon Combiners/Casimir Crystals).
  • Because total galactic supply of some rare veins is limited, plan which recipes will use those deposits and apply Veins Utilization to extend their lifespan. Reserve rare deposits for bottleneck items where feasible.

Power, fuels, and item choices for farming efficiency

  • Energetic Graphite (smelted from Coal) and Combustible Units are common refined fuels. Energetic Graphite is efficient for Mech and early power; Combustible Units have higher per-item energy and different burn modifiers. Choose fuels based on whether they power Mech, Thermal Power Stations, or are carried between systems.
  • Energetic Graphite can be produced via X-Ray Cracking / Oil Refinery chain as an alternative feed if coal is scarce—this trades complexity for resource flexibility.
  • Proliferators (Mk.II, Mk.III) applied to production lines increase output or speed at the cost of higher energy draw. Use proliferators selectively on bottleneck production (matrices, diamonds, high-value craft items). Mk.III requires Carbon Nanotubes and substantial power increases; only apply it when power and materials are abundant.

Logistics and location decisions

  • Smelt ore where it is mined when possible (silicon notably benefits from local smelting into High-Purity Silicon), to reduce interstellar shipment volume and save logistics trips.
  • Place production for hydrogen-heavy or high-fuel-demand items near Orbital Collector stations or fractionators to minimize shuttle distances and latency.
  • For very high hydrogen/deuterium throughput (Casimir, Strange Matter, fuel rods), locate multiple Orbital Collector stations across satellites and operate many Fractionators/Fusion systems in parallel.

Practical build-order recommendations

  1. Early game: automate Coal mining → Smelters → Energetic Graphite for power and initially for diamonds; set up Mining Machines for iron, copper.
  2. Mid game: unlock Oil Extractors and Oil Refinery chains for Graphene and Organic Crystals; research Veins Utilization to extend vein life and increase yields.
  3. Once available: secure a Giant (Gas or Ice) and place Orbital Collectors on the equator for Hydrogen/Deuterium/Fire Ice. Prioritize Veins Utilization levels to maximize collector returns.
  4. Late game: build Advanced Mining Machines and logistic stations for high-throughput veins; set up fractionators and fusion plants for Deuterium and high-energy fuel rods; locate heavy-demand production (Casimir/Growth matrices, Carbon Nanotubes, Graviton lenses) close to resource sources.

Common pitfalls and mitigation

  • Ignoring Veins Utilization leads to faster depletion of finite veins and lower long-term yields. Research it early and invest repeatedly for late-game stability.
  • Building Orbital Collectors without accounting for the 30 MW power draw can make usable resource yield much lower than displayed. Calculate effective boost after subtracting the collector’s fuel consumption or place collectors on Giants with generous high-energy resource mixes.
  • Underestimating hydrogen demand for Casimir/Quantum/Gravity matrixes leads to bottlenecks: plan orbital collection and fractionation capacity ahead of scaling those recipes.
  • Rare deposit dependence: avoid making single rare-vein items the sole supplier for broad production unless you intend to preserve that deposit via Veins research and careful allocation.

This covers the essential farming systems and design principles to build reliable resource supply chains through the game stages. Prioritize Veins Utilization, place Orbital Collectors on suitable Giants for hydrogen isotopes, and colocate heavy consumers with their resource producers to minimize logistic strain.
