Weigh out your stock tanks.
Work out how many gallons of stock you need, then get the weight of each CropSalt product for a 1:128 injector, in grams and pounds.
Weights for 5 US gallons of finished stock in each tank. Each tank feeds 640 US gallons of water at 1:128.
| Tank | Grams | Pounds + grams | Pounds |

Mix each tank separately.
- Use separate containers. One for A, one for B. Keep A and B apart at every step.
- Start with 70% water. Fill each container about 70% full with water.
- Add the weighed product. Part A into the A tank, Part B into the B tank. Mix each well.
- Fill to the final volume. Top up with water to the finished volume, mix well and let the powder fully dissolve. Salt + water = total volume.
- Set both injectors to 1:128. That’s 0.8%, or 30 mL of each concentrate per gallon of water. To raise or lower EC, adjust both injectors equally.
- Finish with Cake. During the Cake finish, run Cake through one injector and turn the other off.
When to switch tanks
Run Veg A + B from clone through day 21 of flower, then Bloom A + B from day 22. On a 9-week flower, run Cake alone for the final 2 weeks; on longer cycles, the final 2.5 weeks.
Concentrate feed chart ↗What it should read
A + B together at 30 mL per gallon each read about EC 2.1–2.5 (1050–1250 ppm, 500 scale). Tap or well water may read higher.
