### 2.1 Standard Operating Procedure (Front Row Ag 3-2-2)

To ensure consistency across large reservoirs, we utilize the "3-2-2 Stock Concentrate" method.

**Production Stock (50 Gallon Drum):**

- **Part A:** 3 Bags (75 lbs). Target EC ~2.9.
- **Part B:** 2 Bags (50 lbs) + 6 lbs Phoszyme. Target EC ~1.69.
- **Bloom:** 2 Bags (50 lbs).

**Test Stock Protocol (16 Gallon):**
Used for small scale trials. Scaled by 0.32 (16/50).

- **Part A Stock:** 24 lbs Part A into 16 gal RO.
- **Part B Stock:** 16 lbs Part B + 864g PhosZyme into 16 gal RO.
- **Procedure:** Fill canister to 50% (8 gal), add dry product over 5 mins, top up to 16 gal, mix for 10 mins.

### 2.2 Dosing & Validation

- **Validation:** Every stock batch must be validated for pH (5.8-6.0) and EC before being plumbed into the Dosatron injection system.
- **Application:** Dosing pumps draw from these valid stock concentrates to feed room reservoirs based on the recipe phase (Vegetative vs Flower).
