How to Crossbreed Strains and Track Progress in the Herbarium

Once you have mature wild landraces growing in your base, you can begin crossing parent plants to discover classic strains and fill out your research records.

Using the Herbarium Journal

The Herbarium serves as your personal research guide for genetic breeding. When you first begin, entries in the Herbarium appear locked while awaiting your discoveries.

1. Open your Herbarium to view your current research records and see which slots remain locked.

2. Check completed entries at any time to review unlocked plant varieties and inspect full family trees.

3. Use those family tree diagrams to keep track of which parent crops you have already paired together.

Crossing Mature Parent Crops

Unlocking famous strains requires combining genetics from separate parent plants rather than replanting the same wild seeds repeatedly.

1. Grow at least two different wild landraces or unlocked varieties side by side in rich soil under UV grow lamps until both crops are fully mature.

2. Cross the mature parent crops to breed a new hybrid strain variety.

3. Open the Herbarium after harvesting or producing the new cross to confirm that the new strain and its branch on the family tree have unlocked.

4. Repeat this process by pairing newly unlocked strains with other crops to uncover deeper tiers of your research guide.
