Mixing & Application Guide
Step-by-step mixing order, stock & batch tank procedures, usage rate tables, and Condition Line dosing, the working reference behind every HGV feed.
Dry Step By Step
Mix dry bags separately into water at desired concentration.
→ Follow HGV stock tank mixing SOP.
Validate usage rates.
→ Use usage guidelines to confirm EC targets.
Input injection rates into dosers or ml/gal in batch tanks.
Verify EC and pH.
Liquid Step By Step
Validate usage rates.
→ Use usage guidelines to confirm EC targets.
Input injection rates into dosers or ml/gal in batch tanks.
Verify EC and pH after mixing.
Always verify EC and pH at the point of delivery to ensure accuracy.
Dosatron Configuration
Using PH+ Products
Recommended Mixing Order:
- HGV Clear (Hypochlorous Acid)
- HGV Base (Calcium Nitrate)
- HGV Flower Or HGV Grow
- HGV PH+ (Or Equivalent)
Using PH- Products
Recommended Mixing Order:
- Clear (Hypochlorous Acid)
- HGV Base (Calcium Nitrate)
- HGV Flower Or HGV Grow
- HGV PH- (Or Equivalent)
Using Level Products
Recommended Mixing Order:
- HGV Level (Or Potassium Silicate Equivalent)
- HGV Base
- HGV Flower Or HGV Grow
- Clear (Hypocholorous Acid)
Stock Tank Mixing
1. Add Water
Fill tank to 70% of final volume. Warm or hot water is preferred.
2. Add HGV
While agitating, add total Lbs/Gal weight of HGV Flower or HGV Grow.
3. Add Water & Mix
Fill tank to full target volume. Continue to agitate until fully dissolved.
4. You're Done!
Your liquid concentrate is now ready to dose.
Batch Tank Dosing with either liquid concentrate or g/gal
1. Add Water
Add water to tank (total volume).
2. Add Base
Add HGV Base (or Cal. Nitrate) to tank, let mix for 5 minutes.
3. Add HGV
Add HGV Flower or HGV Grow to tank, let mix for 5 minutes.
4. Check EC, Adjust pH
Once you achieve a target EC of 3.0 and pH range of 5.6-5.8, it is ready to use.

Other Guidelines
- Concentration is determined by doser capacity and water temp.
- Acceptable Mix Rates: 0.5, 2.5 Lbs/Gal
- Stock tank mixing - Calculate volume for entire bag usage
- Once stock tank is mixed, there is no need to agitate further

Usage Rate Adjustment Calculator
If usage rate does not obtain target EC, use the formula below to adjust.
- Actual EC ÷ Target EC = Difference
- Current mL/Gal ÷ Difference = New Value
- New Value will achieve target EC
Example:
2.5 EC ÷ 3.0 EC = 0.833
15 ÷ 0.833 = 18
25 ÷ 0.833 = 30
New Usage Rate Value: Base = 18 Grow/Flower = 30
