POWDER Mixing & Injection Guide

Clean, simple, and scalable ways to run the POWDERS.

Stock Concentrate Mix Rates

ProductStock RatePrimary Function
Powder A2 lb/galNitrogen + Calcium
Powder B2 lb/galPK + Secondary Support
Powder C1 lb/galFlowering PK Boost
Powder D40 g/galChelated Micronutrients

1. Batch‑Tank Mixing (Standard)

  1. Fill the tank to 100 % of its final volume with RO or clean tap water.

  2. Add, agitate, & dissolve each POWDER individually, and in order: A → B → C → D.

  3. Feed immediately or store up to 7 days with recirculation.

Why water first? Full dilution prevents local hot‑spots, keeps everything crystal‑clear, and preserves chelates.

2. Four‑Tank System (Standard Commercial Method)

  1. Fill the stock tank to 100 % of its final volume with RO or clean tap water.

  2. Add Powder, agitate until fully dissolved.

3. Three‑Tank System (A + D Combined)

Tank Order Contents / Stock Rate (25‑gal baseline) Preparation Options
A + D 1st 50 lb A +  1000 g D
  • Dry‑blend: Combine powders dry first, then dump into 25 gal water and agitate.
  • Liquid pre‑mix: Dissolve A in 20 gal, D in 5 gal, then combine.
    		•
    B 2nd 2 lb/gal Standard single‑part mix.
    C 3rd 1 lb/gal Standard single‑part mix.
    Injector Order: A + D → B → C Late‑Flower Nitrogen Drop: When you want to remove nitrogen but keep micros, swap the A + D tank for a stand‑alone D stock (40 g/gal) and leave B & C unchanged.

    4. Dual‑Tank System (Base & Bloom Barrels)

    A two‑tank, 50‑gallon setup that delivers high-strength feeds while preserving solubility, protecting chelates, and keeping flow consistent.

    Why Calcium (A) Must Follow the PK+Micro Barrel

    Injecting calcium‑nitrate after the PK+Micro barrel keeps the solution crystal‑clear and the chemistry on point:

    • Stops Ca‑P / Ca‑S scale before it starts. At 2 lb/gal, both stocks are highly concentrated. If Ca²⁺ meets fresh PO₄³⁻ or SO₄²⁻ too soon, they exceed their solubility product and form rock‑hard precipitates that clog emitters.
    • Protects your chelated micros. Chelates keep Fe, Mn, Zn soluble—until a surge of Ca²⁺ strips them out. Letting PK + micros dilute first shields the chelates from displacement.
    • Stabilises pH & EC spikes. A calcium‑rich slug can momentarily raise pH and EC. Injecting it second smooths those spikes, giving you a consistent, predictable feed.
    • Matches plant uptake rhythm. Plants pull more Ca earlier in the irrigation stream; leading with PK front‑loads bloom nutrients and lets calcium polish the profile on the way to the drippers.

    Injector Layout: Mainline → Bloom Barrel injector → 12‑18″ mixing pipe or in-line mixing tank → Base Barrel injector → optional Flow/Shock → filters → zones.
