I tested the bronto lunar biome strategy on 1x official. You farm the crystal from the grass there. I collected 15k within 300 feet of distance. Hands down best way to ever farm crystal but it is not easy for beginners. I would have died without a tek canteen because I was unprepared. You are going to want a hazard suit or a tek suit to block the extreme temperatures and radiation. And a hover skiff is highly recommended for transporting the crystal and the bronto.
