How do seed packs work?
Opening seed packs gives you seeds that you can plant and water at your base. A pack is the acquisition step; the seed is the item you use in the planting step.
The official description confirms that loop, but it does not give a full pack-price table or pack-specific probabilities. Pack availability, price and listed contents should come from your current game interface.
Choose a pack with a fixed budget
Write down current cash
Use your current balance, not a creator's balance or a promotional screenshot.
Keep a reserve
Set aside what you need for a known next step such as an upgrade. This reserve is a personal choice, not a fixed game requirement.
Read the pack offer
Check its exact name, price and any displayed contents or odds. A rarity badge alone is not a percentage.
Calculate the purchase ceiling
Use the seed-pack calculator with balance, reserve and price. Buy only within the ceiling if you intend to preserve that reserve.
Recheck after opening
Review the actual seed result and updated cash. Do not keep buying solely because earlier packs did not produce the plant you wanted.
Does opening more packs guarantee a secret plant?
No guaranteed secret threshold is verified in the sources used here. A budget ceiling says how many packs you can afford, not what those packs will contain.
Only use a pity counter or guarantee if the current game explicitly displays it and explains its conditions. The calculator deliberately avoids simulating unverified pack odds.
Questions answered
Where are pack prices in the calculator?
The calculator asks you to enter the current price. It does not ship a fixed price list that could be wrong after a game update.
