FAQ

What EC should I feed at?

Given the variance in facility infrastructure, cultivation methods, and cultivars, it’s impossible to give a specific EC prescription that applies to all scenarios. Most facilities feed at 2.0-3.0 EC with Front Row Ag, and our “Standard” and “High Strength” Feed Charts reflect effective feeding strategies in this range. The following table shows some considerations that affect EC choice:

Do I need to use Cal Mag with Front Row Ag?

No, our formula contains ideal ratios of calcium and magnesium based on years of testing and plant tissue analysis. If deficiencies are observed, raise EC by increasing all parts equally to maintain ideal mineral ratios.

Do I need a bloom booster with Front Row Ag?

No. you will not need an additional bloom booster - Front Row Ag Bloom contains all the required micronutrients with ideal quantities of phosphorus and potassium to maximize density, yield, and quality.

What is the cost per gallon for Front Row Ag using Part A, Part B, and Bloom?

$0.026 per gallon at 2.6 EC with commercial pricing.

What is the proper injection order for Front Row Ag?

1. Front Row Si

2. Part A

3. Part B

4. Part Bloom

5. Clean Up (or pH down if necessary)

Why feed at higher EC early in the cycle?

Plant nutrition requirements are highest during the stages at which plants are growing most quickly, veg and during the first three weeks of flower. At this stage the crop will have a smaller root mass and drybacks will take much longer. As the plant finishes stretch, mineral requirements will be reduced and substrate EC should also be reduced via lower feed EC and/or increased runoff.

How is Front Row Ag different from other mineral fertilizers?

Front-Row Ag uses the highest purity agricultural inputs containing precise blends of micronutrients, chelates, complexing agents and surfactants.

What is the easiest way to use Front Row Ag?

Using dosatrons or an injection system with our 3-2-2 Stock Concentrate Mixing is the easiest method. This allows use of whole 25lb bags in 50 gal stock barrels that can be injected at equal injection ratios.

How do I use Front Row Ag for clones or seedlings?

How long can Front Row Ag be stored for?

How long can Front Row Ag be stored for?

Solutions should be stored in opaque containers in climate controlled areas.

Can Front Row Si be injected?

Yes, at 0.03-0.13 ml/L. There are two important considerations with injecting Si:

• Higher feed EC requires lower usage rate of Si.

• If the injection system is filling batch tanks, they must be fully used within 48 hours.

Why does Front Row Ag improve quality, aroma, and yield?

For Direct to Reservoir mixing what is the required mixing time between adding each part?

• 3-5 minutes between Si, A, B, Bloom.

• 5-15 minutes between additions of Clean Up, to allow for full pH adjustment effect.

What causes color change or cloudiness of fertilizer solution in a reservoir?

Turbidity or “haziness” of the feed solution can be caused when bacteria or oxidizing chemicals react with certain metal micronutrients, forming suspended particles and changing the solution color. While this does not cause any functional problems with the fertilizer, it can be an aesthetic or cleaning issue. Turbidity can be avoided by following a few key practices in water quality and sanitation. Most often it is caused by strong oxidizing agents, especially hydrogen peroxide compounds, reacting with the high concentration of micronutrients in Front Row Ag. It can be avoided by removing these from the feed solution and triple-rinsing tanks prior to cleaning with these solutions.

How often should I clean my batch tanks?

As needed, depending on each facility’s inputs and water quality. Generally every 10-14 days is recommended, although facilities running a sterile irrigation system will require cleaning less frequently and facilities running microbial additives may require more frequent cleaning.

How do I spray Front Row Si?

0.13-0.53 ml/L, sprayed weekly up to day 21 of flower.

Our formula’s high quality soluble minerals and full spectrum of micronutrients has been engineered specifically for the plant’s needs.

Do Front Row Ag users test for heavy metals?

Yes, we have hundreds of customers in markets with stringent heavy metal limits that use Front Row Ag to ensure finished products have low levels of heavy metals.

How often should my irrigation components be replaced?

Generally everything downstream from hard plumbing (primarily poly line and drip emitters) should be replaced annually.

How often should I clean my fertigation skid?

1-2 times per month is an ideal cleaning frequency to ensure cleanliness and consistent functioning of fertigation equipment.

How much does each FRA part raise the EC per gram per liter?
