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:

Unlike Frost Crystals, Solanium thrives on hot and arid planets. Before landing, use your starship scanner to identify planets with descriptions like "Arid," "Incandescent," "Boiling," or "Scorched." The scanner will also indicate Solanium as a resource.

Upon landing, deploy your Analysis Visor to locate Solar Vines – tall, rock-like structures with glowing vines. These are abundant in specific areas. Remember, you'll need a Haz-Mat Gauntlet to harvest them. While on these planets, also collect Phosphorus; it's a key ingredient in Solanium crafting.
Farming Solanium:

Once you've progressed in the Farmer's Agricultural Research mission, you can cultivate Solar Vines at your base. Use a Hydroponic Tray or Bio-Dome, planting each vine with 50 Solanium and 50 Phosphorus. If your base is situated on a hot planet, direct ground planting is possible.
Harvesting takes approximately 16 real-time hours.
Crafting Solanium:

The Refiner offers several Solanium crafting recipes, most requiring Phosphorus (often obtained from hot planets). Alternatively, purchase Phosphorus from traders or Galactic Trade Terminals. Recipes include:
- Solanium + Phosphorus (to create more Solanium)
- Phosphorus + Oxygen
- Phosphorus + Sulphurine
- Di-hydrogen + Sulphurine
Note: Most crafting methods necessitate a visit to a hot planet, especially for Sulphurine. Establishing a Phosphorus farm at your base ensures a consistent Sulphurine supply.
