Update 4 Feature
Plant Contracts Guide
Plant Contracts are quest-like objectives in Update 4. This guide covers every contract type, the best rewards to target, and how to integrate contracts into your daily farm routine without disrupting your income.
Contract types
Three Contract Categories
Daily Harvest Contracts
24 hours | Easy
Rewards: Fertilizer, basic seed packs, small cash
Tip: Accept every daily contract — the time investment is minimal and rewards accumulate.
Weekly Master Contracts
7 days | Medium-Hard
Rewards: Mutation sprays, rare seed packs, pet items
Tip: Plan your farm around weekly contracts. Check requirements before choosing which seeds to plant.
Event Contracts
Event-limited | Hard
Rewards: Exclusive cosmetics, premium sprays, rare pets
Tip: These run alongside game events (Starfall, Admin weeks). Prioritize event contracts over base game activities.
Strategy
5 Steps to Master Plant Contracts
1. Keep a Diverse Seed Inventory
Maintain a buffer of every seed tier from Common through Legendary. This lets you accept any contract immediately instead of waiting for the right seed to grow.
2. Stack Contracts with Events
Event contracts (Starfall, Admin, Fire weeks) run alongside the regular rotation. Complete both simultaneously by planning your farm around their overlapping requirements.
3. Use Compost Rewards for Contract Fuel
The Compost Machine generates event tickets and seed packs that directly feed into contract requirements. Run the Compost Machine continuously to maintain contract material.
4. Prioritize Mutation Spray Contracts
Mutation sprays (Autumn, Wet, Fire) are the most versatile contract rewards. They help complete future mutation-related contracts while also boosting your income.
5. Track Expiry Timers
Accept contracts as soon as they refresh. The 24-hour daily cycle means missing one day costs you 1/7th of your weekly contract income.
Reward priority
Contract Reward Tier List
A-Tier Rewards
Mutation sprays (Autumn, Fire, Wet). These boost harvest value and help complete future mutation contracts. Always worth pursuing.
B-Tier Rewards
Rare seed packs, fertilizer, event tickets. Useful for maintaining your farm but not worth disrupting your main income strategy.
Integration
Contracts + Compost Machine + Profit Calculator
The three Update 4 systems work together. Run the Compost Machine to generate event tickets and seed packs. Use those resources to complete Plant Contracts faster. Use the profit calculator to check whether completing a contract is worth more than your standard harvest routine.
Frequently Asked Questions
What are Plant Contracts in Build A Ring Farm?
Plant Contracts are daily and weekly quests introduced in Update 4. Each contract requires you to plant specific seeds, reach harvest milestones, or achieve mutation-related goals in exchange for rewards including seed packs, mutation sprays, exclusive items, and pet-related rewards.
How do I access Plant Contracts?
Open the Contracts menu from the in-game UI panel (usually located next to the Compost Machine or in the main farm interface). Available contracts rotate on a daily and weekly schedule.
What are the best contract rewards?
Prioritize contracts that reward pet items (especially Harvest Drone or Rain Cloud upgrades), mutation sprays, and rare seed packs. Skip cosmetic-only contracts unless you have excess capacity.
Should I keep seeds specifically for contracts?
Yes. Maintain a buffer of at least 5-10 of each Common and Uncommon seed type so you can accept any contract without disrupting your main income farm.
Do contracts expire if I don't complete them?
Daily contracts expire after 24 hours. Weekly contracts expire after 7 days. Completed contracts are replaced with new ones after their refresh timer.
