Uses

• Seed Harvest: Biodome harvests are a bit different compared to what you get out in the wild. Instead of Organic, you can harvest Seeds from most regular plantable plants in the Biodome (excluding hazardous plants, LTE Plants and Fractal Roses). Plants will require more care and attention, but their yields will be greater. Seeds are a resource that plays into one of the Museum’s Donation Station rewards.
• Rare Drops: There’s a small chance for harvested plants in the Biodome to drop extra goodies for you to discover. Only the newly added seeds are capable of this (more info on the new seeds further down in the free content section).
• Upgrade Stages: Upgrading the Biodome to Stage 2 adds the Mega-Grow Lamp, which boosts plant growth rate within the Biodome. Stage 3 adds a Megastructure Component Printer.
• Megastructure Component Printer: A Stage 3 Biodome will have the ability to print its associated Mega Modules, listed above.

Resource Production

At least some Seeds, when planted on one of the Biodome's seed slots, have a chance to yield a resource when harvested.
