No Man's Sky: A Comprehensive Guide to Obtaining Solanium
Solanium, a crucial resource in No Man's Sky, is exclusively found on planets with specific climates. This guide details how to acquire Solanium through gathering, farming, and crafting.
Locating Solanium

Solanium is similar to Frost Crystals but thrives in hot, arid environments. While in space, scan potential planets for indicators like "Arid Planet," "Incandescent Planet," "Boiling Planet," or "Scorched Planet." The presence of Solanium will also be listed in the resource scan.

Once landed, utilize your Analysis Visor to locate Solar Vines – tall, rock-like structures with luminous vines. These are abundant in these regions. Remember, you'll need a Haz-Mat Gauntlet to harvest them. Phosphorus, also found on these planets, is a key ingredient in Solanium crafting, so collect it if available.
Farming Solanium

After progressing the Farmer's Agricultural Research mission, you can cultivate Solar Vines. Plant them in a Hydroponic Tray or Bio-Dome using 50 Solanium and 50 Phosphorus. Hot planets allow direct ground planting. Harvesting occurs after approximately 16 real-time hours.
Crafting Solanium

Several Refiner recipes yield Solanium, most requiring Phosphorus (obtainable on hot planets or from traders/Galactic Trade Terminals). Here are the recipes:
- Solanium + Phosphorus (to create more Solanium)
- Phosphorus + Oxygen
- Phosphorus + Sulphurine
- Di-hydrogen + Sulphurine
Note that all methods, including those using Sulphurine, necessitate visiting a hot planet. Establishing a Phosphorus farm at your base ensures a consistent Sulphurine supply.
