INGREDIENT CHECK · OCTOBER 3, 2026

Schedule 1 ingredients: when repeats only add cost

The answer: a repeated ingredient can increase cost without changing your final effects or selling value. In our OG Kush → Cuke → Banana example, adding Banana again leaves the calculated selling price at $66 but reduces ingredient-only profit from $62 to $60 per unit. Check the result after each step rather than assuming every addition improves a recipe.

This is an original step-by-step simulation using the engine on this site. All amounts are in-game values. It does not establish that every repeated ingredient behaves the same way in every recipe or game version.

Our controlled ingredient test

We kept the base product at OG Kush and used standard mixing with Seeded Mixing off. We changed only the ordered ingredient list. Production cost was left at zero to isolate the expense added by ingredients; the profit column therefore excludes base production cost and other expenses.

Ordered additions	Cost / unit	Sell value / unit	Ingredient-only profit
None	$0	$39	$39
Cuke	$2	$46	$44
Cuke → Banana	$4	$66	$62
Cuke → Banana → Banana	$6	$66	$60
Cuke → Banana → Banana → Banana	$8	$66	$58

The first Banana changes the result to Sneaky, Thought-Provoking and Gingeritis. The next two Banana additions retain that same three-effect set. Each still adds $2 of expense. This is a repeated-ingredient example with only three effects, so the unchanged output cannot be attributed to reaching the eight-effect limit.

Measure the extra step, not just the final price

For an added ingredient, compare the change in selling value with its added cost. In this test the first Banana raises value by $20 and costs $2, improving ingredient-only profit by $18 per unit. Each later Banana raises value by $0 and costs $2, reducing that profit by $2 per unit.

Original chart from our five saved engine runs. The vertical line is zero; these are simulated changes, not observed player earnings.

At 20 units, the second Banana alone adds $40 of ingredient expense without increasing calculated batch sell value. Adding both the second and third Banana adds $80. This conclusion keeps quantity and base production cost fixed; changing either would make it a different comparison.

Reproduce the check on this site

Open the calculator, reset the recipe and select OG Kush.
Add Cuke, then Banana. Note the effects, ingredient cost and unit sell price.
Add Banana once more. Compare the same fields before and after.
Open “What changed at each step?” to inspect the trace. Remove the final Banana to compare again.

Questions about repeated ingredients

Does this mean I should never repeat an ingredient?

No. Our test covers one ordered recipe. An ingredient's effect depends on the state present when it is added. A repeat in another sequence may participate in a transformation. Test that sequence instead of treating this example as a universal ban.

Is a higher selling value always a better step?

No. Subtract the extra expense from the extra calculated value. A value increase smaller than the ingredient's price would still reduce ingredient-only profit. This simple comparison does not model time, equipment or customer demand.

Does unchanged output mean the calculator ignored my click?

Check whether the ingredient appears as another step and whether its cost was added. In this example both happen even though the effects and value stay unchanged. If the step itself did not appear, that is a separate interface issue.

Source and limits

We ran these five cases on October 3, 2026 using this site's engine, adapted from the MIT-licensed Schedule1 Tools snapshot 74607081. The source does not specify an exact game build. The table, marginal comparison and chart were produced for this article; they are simulations rather than a test in a live game save.

For a different base product, order or rule version, repeat the same before-and-after check. For production expenses, read our separate production-cost comparison.
