How much prepared solution does the Feeding Program make?
The Feeding Program contains 1 liter Houseplant Formula and 1 liter Sea-Prime for ongoing plant care. The table shows the prepared volume when both formulas are diluted separately and used in the standard alternating soil-feeding routine.
| Formula | Bottle size | Soil dosage | Prepared solution |
|---|---|---|---|
| Houseplant Formula | 1 liter | 5–15 ml/L | 66–200 L |
| Sea-Prime | 1 liter | 5–10 ml/L | 100–200 L |
| Total across alternating soil feedings | 166–400 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 1 liter bottle preparing approximately 200–500 liters of foliar solution. This optional foliar volume is not included in the combined soil-feeding total.
