How much prepared solution does the Starter Pack make?
The Starter Pack contains 500 ml Houseplant Formula and 500 ml Sea-Prime. For the standard feeding routine, dilute each formula separately and alternate them between soil-feeding applications.
| Formula | Bottle size | Soil dosage | Prepared solution |
|---|---|---|---|
| Houseplant Formula | 500 ml | 5–15 ml/L | 33–100 L |
| Sea-Prime | 500 ml | 5–10 ml/L | 50–100 L |
| Total across alternating soil feedings | 83–200 L | ||
The total represents separate, alternating soil applications of Houseplant Formula and Sea-Prime; it is not an instruction to mix the two concentrates. Sea-Prime can alternatively be applied as a foliar spray at 2–5 ml/L, with the 500 ml bottle preparing approximately 100–250 liters of foliar solution.
