Space Haven Trading Guide
Trading is the engine that transforms a struggling survival ship into a thriving space economy. In Space Haven, your ship produces resources, but production alone does not generate credits unless you sell the surplus. Learning which goods to sell, to whom, and when is the difference between scraping by on emergency power and expanding your fleet with top-tier equipment. Food is the most common entry point for new traders, but the real money is in understanding faction preferences, price fluctuations, and the reputation economy that governs the entire trade system. This guide covers every trade good, every faction's preferences, and the strategies that experienced traders use to build wealth.
How to Sell Food — The Foundation of Trade
Selling food is the most accessible and reliable way to generate credits in Space Haven. Every faction except the Android Collective and Tech Union needs food, and several factions pay premium prices for it. The food trade starts with a simple question: how much surplus can you reliably produce? Each Grow Bed produces approximately 5-8 food units per cycle depending on your botanist's skill level and crop type. A basic farm room with 6 Grow Beds and a Level 5 botanist produces 35-45 food per cycle.
To sell food, dock at any friendly station and use the trade terminal. Select the food items in your ship inventory and drag them to the sell window. The station's current buy price appears at the top of the trade panel. Prices update every cycle based on the station's current food stockpile. Stations with less than 100 food units in storage pay the highest prices. Stations with over 500 food units pay minimum prices or stop buying entirely until their stockpile depletes.
The most profitable food trade strategy is to cultivate relationships with 3-4 stations in different sectors, sell food at each station in rotation, and never sell more than 150 units to any single station per visit. This prevents price crashes from oversupply. Rotating between four stations generates approximately 8000-12000 credits per cycle from food alone, which is enough to fund a mid-game ship expansion every 10 cycles.
Trade Goods — Complete Price Guide
Every trade good has a price range based on faction demand, supply scarcity, and current game state. The profit margins below represent optimal selling conditions to the right faction.
| Item | Buy Price Range | Sell Price Range | Best Faction to Sell To | Profit Margin |
|---|---|---|---|---|
| Raw Food (Vegetables) | 8-12 credits per unit | 15-22 credits per unit | Slavers Guild and Pirates. Both factions constantly need food for their large captive populations and pay premium prices. | 80-120% profit. Highest volume trade good in the game. A dedicated farm ship producing 200 food per cycle generates 3000-4400 credits of pure profit. |
| Infra Blocks | 25-35 credits per block | 40-55 credits per block | Mining Guild and Military Alliance. Both factions use Infra Blocks constantly for expansion and command higher demand-driven prices. | 50-70% profit. Better to sell during faction expansion phases (every 15-20 cycles) when demand spikes. Stockpile during low-demand periods. |
| Tech Blocks | 40-60 credits per block | 70-95 credits per block | Android Collective and Tech Union. These technology-focused factions pay premium prices for advanced components. | 60-80% profit. Higher margin than Infra Blocks but slower production volume. Best for mid-game when you have spare advanced assembler capacity. |
| Energy Blocks | 55-75 credits per block | 90-120 credits per block | All factions during power crises. Energy block prices spike 50-70% when a faction loses its main power generator. | 60-90% during normal market, 120-180% during crisis. Monitor faction power status and sell during brownouts for maximum profit. |
| Weapons (Basic) | 150-200 credits per unit | 300-450 credits per unit | Military Alliance and Pirates. Pirates pay 20% more but trading with them damages reputation with lawful factions. | 100-125% profit. High margin but low volume. Weapons are best as supplemental income when you have excess industrial capacity. |
| Medical Supplies | 30-50 credits per unit | 55-80 credits per unit | Civilian Outposts and Refugee Fleets. These factions have constant medical needs and limited production capacity. | 60-80% profit. Consistent demand regardless of faction state. Medical supplies are the most stable trade good with the least price fluctuation. |
| Water (Bulk) | 5-8 credits per unit | 12-18 credits per unit | Desert biome outposts and stations with damaged water purifiers. Demand spikes after pirate attacks on station infrastructure. | 100-140% profit. Water is cheap to produce but heavy to transport. Only profitable in bulk shipments of 100+ units per trade run. |
| Exotic Materials | 500-800 credits per unit | 1200-2000 credits per unit | Android Collective and Tech Union. Exotics are the ultimate late-game trade good. Limited production means prices never crash. | 140-150% profit. Extreme margin but requires exotic research unlock and dedicated production facility. One unit of exotic materials sells for the price of 40 Infra Blocks. |
Profit figures reflect typical mid-game market pricing and may shift with colony supply.
Faction Trading Preferences — Complete Guide
Each faction has distinct preferences, hates, and relationship bonuses. Trading the wrong goods can damage relationships faster than not trading at all.
| Faction | Preferred Goods | Hated Goods | Relationship Bonus |
|---|---|---|---|
| Mining Guild | Infra Blocks, Mining Equipment, Energy Blocks | Weapons. Trading weapons to the Mining Guild triggers a relationship penalty as they view armament as a sign of hostile intent. | +2 relationship per 500 credits traded. Reaching Friendly status unlocks discounted ore purchases at 30% below market rate. |
| Military Alliance | Weapons, Energy Blocks, Medical Supplies | Raw Food. The Military Alliance produces its own food and views food imports as an insult to their self-sufficiency. | +2 relationship per 400 credits traded. Allied status unlocks military escort missions that pay 2000-5000 credits. |
| Android Collective | Tech Blocks, Exotic Materials, Energy Blocks | Raw Food and Medical Supplies. Androids do not eat or get sick. Offering these goods reduces relationship. | +3 relationship per 500 credits traded. Best relationship-per-credit ratio. Friendly Androids offer technology trades unavailable elsewhere. |
| Slavers Guild | Raw Food, Water, Medical Supplies | Weapons. Arming slaves is the Slavers Guild's greatest fear. Trading weapons results in immediate -10 relationship penalty. | +1.5 relationship per 500 credits traded. Lower bonus but slavers are the easiest faction to trade with due to constant raw material demand. |
| Pirates | Weapons, Raw Food, Energy Blocks | Medical Supplies. Pirates view medical supplies as evidence you are treating their enemies. -5 relationship per trade. | +2 relationship per 300 credits traded. Highest relationship gain per credit but trading with pirates damages reputation with every other faction by -1 per 500 credits. |
| Civilian Outposts | Medical Supplies, Raw Food, Water, Infra Blocks | Weapons and Exotic Materials. Civilians are non-combatants; trading weapons terrifies them and exotics are beyond their needs. | +1 relationship per 500 credits traded. Low bonus but civilians offer the most consistent demand. Safe trading partner that never draws faction hostility. |
| Tech Union | Tech Blocks, Exotic Materials, Energy Blocks | Raw Food and Infra Blocks. The Tech Union considers basic materials beneath their technological focus. | +3 relationship per 600 credits traded. Slightly lower than Androids but Tech Union offers exclusive blueprint trades at Friendly status. |
| Refugee Fleets | Medical Supplies, Raw Food, Water | Weapons. Refugees are traumatized by conflict. Trading weapons causes -8 relationship penalty. | +2 relationship per 400 credits traded. Helping refugees builds reputation rapidly. Refugee fleets sometimes offer crew recruits as thanks at Friendly status. |
Advanced Trading Strategy — Price Manipulation
Experienced traders do not just sell at whatever price the station offers. They manipulate markets by creating artificial scarcity or abundance. The most profitable technique is called the Starvation Cycle: identify a station that is the sole food supplier for a sector, buy out their entire food stockpile (1000+ units at minimum price), then watch as the surrounding stations starve. When those stations are desperate for food (stockpile below 50 units), sell them food at the maximum crisis price of 22 credits per unit compared to the 8 credits you paid.
The Starvation Cycle earns approximately 14000 credits profit on a 1000-unit food trade. The cost is reputation damage: stations that starve lose 5-10 relationship points with you if they discover you caused the shortage. Mitigate this by spreading your sales across sectors so no single station can trace the shortage to you. Always maintain at least Neutral relationship with 3+ factions before attempting market manipulation.
The safer strategy is the Quality Supplier approach: consistently sell preferred goods to the same 2-3 factions at fair prices without market manipulation. This builds relationship points steadily and unlocks faction-exclusive benefits (discounted ore from Mining Guild, military escorts from Military Alliance, exotic technology trades from Android Collective) that compound into economic advantages worth more than short-term market manipulation profits.
Frequently Asked Questions
Q: How do I sell food when no station nearby is buying?
Stations stop buying food when their stockpile exceeds 500 units. You have three options. First, jump to a different sector where stations have lower stockpiles. Second, wait 3-5 cycles for station stockpiles to deplete naturally as their populations consume food. Third, if you have high enough reputation, you can offer food as a gift to build relationship even when they are not buying. The gift still counts toward your trade volume for relationship bonuses, though you receive no credits.
Q: Is trading with pirates worth the reputation hit?
Pirates pay 20 percent more than lawful factions for weapons and food, but every trade with pirates reduces your reputation with all lawful factions by 1 point per 500 credits traded. The reputation hit is temporary and recovers at roughly 0.5 points per cycle per faction through normal positive interactions. In the early game, the reputation cost is too high. By mid-game when you have 40+ reputation with key factions, you can afford occasional pirate trades for quick cash. Never let pirate trades drop your reputation with a faction below Friendly once you have achieved that status.
Q: What is the single most profitable trade good?
Exotic Materials are the most profitable per unit with a 140-150 percent margin, but production is limited to the late game and each unit requires a dedicated exotic production facility. Food is the most profitable by volume: the sheer quantity you can produce makes it the highest total-credit generator. A mid-game farm ship producing 200 food per cycle and selling at 20 credits per unit generates 4000 credits per cycle. Exotic materials at 200 credits per cycle selling at 1600 per unit generate 3200 credits per cycle. Food wins on total credits until the very late game.
