At-a-Glance Success Map
- Choose one core base nutrient: Aqua Flakes, Cocos, Hydro or Soil A&B according to your growing medium, then use that base consistently through the appropriate program.
- Use root and vegetative additives during the early-growth stages shown in the feed chart.
- Use enzymes and system conditioners according to their role and the verified feeding program.
- Introduce bloom-stage products in sequence: Bud-XL, then Top Booster, followed by either Shooting Powder or Top Shooter where shown in the feed chart.
- Use the metric feed chart below for exact stage timing and dosage. Do not rely on unlabelled “Week 5” or “Week 6” references elsewhere.
- Follow the correct mixing order: Part A, then Part B, then additives. Check EC and pH after mixing and use the medium-specific targets in the Mixing Protocol section below.
Choose Your House & Garden Base Nutrient
| Variant | Best For | Standard Range | Key Benefits |
|---|---|---|---|
| Aqua Flakes A&B | Recirculating hydro (DWC, ebb-&-flow, rockwool) | 1.5 – 3 mL/L | Low-ppm recipe keeps pH rock-solid in moving solution; Ca & Mg balanced for RO/soft water. |
| Cocos A&B | 40 %+ coco blends | 1.5 – 3 mL/L | Extra Ca & chelated Fe tame coir’s cation exchange; 100 % liquid actives—no blocky powders. |
| Hydro A&B | Drain-to-waste rockwool / perlite / clay | 1.5 – 3 mL/L | Rapid uptake, wide system compatibility; reaches target pH faster than legacy Dutch ABs. |
| Soil A&B | Peat or mineral soils | 2 – 5 mL/L | Extra Ca & traces without crashing medium pH; replaces grow/bloom two-part bottles. |
Important: Choose the base nutrient that matches your growing medium. The feed chart below provides the stage-based Base A&B values used in this guide; always compare those values with the directions for the specific House & Garden base product you are using.
House & Garden Additives
Root & Veg Accelerators
| Product | Dose (mL /L) | Why You’d Use It |
|---|---|---|
| Roots Excelurator | 0.30 | Protective film blocks pythium and sparks root tip explosion in 48 h. |
| Amino Treatment | 0.80 → 1.00 | Sea-kelp amino acids boost chlorophyll & cell division; double after transplant shock. |
| Nitrogen Boost | 0.25 → 1.00 | Pharma-grade N rescues pale clones, fuels rapid leaf mass. |
| Magic Green (foliar) | 10-20 mL/L spray | Instant green-up with Fe & K; spray lights-off to avoid scorch. |
Enzyme & System Conditioners
| Product | Dose (mL /L) | Function |
|---|---|---|
| Multizyme | 1.0 | Breaks down dead roots, frees P & Ca, raises Brix. |
| Drip Clean | 0.10 | Magnetised K isolates salts; keeps drippers clear & flush time short. |
| pH Stabiliser | 1.0 | Locks RO/rainwater at target pH for up to 10 days—perfect for auto-top-off. |
Bloom-Stage Enhancers
- Bud-XL – 1.0 mL/L: Pulls sugars from leaves into flowers, fattening calyces & terps. See the feed chart below for stage timing.
- Top Booster – 1.5 mL/L: PK + EDDHA-iron triggers extra fruit set. Use it only at the stage shown in the feed chart, and do not overlap it with other PK spikes.
- Shooting Powder 0.65 → 1.3 g/L or Top Shooter 0.75 → 1.5 mL/L: Choose one of these products rather than combining them. Use the dosage and stage timing shown in the feed chart below.
- Magnesium 8 % – 0.5 mL/L (as needed): Fast Mg rescue for mid-bloom LED chlorosis.
House & Garden Metric Feed Schedule (per Litre)
How to read this chart: Timing is labelled by growing stage rather than by one continuous week number. Keep these labels exactly as shown—Cuttings/Seedlings, Veg Week 1–2 and Flower Week 1–7—so readers do not confuse an overall program week with a flowering-stage week.
| Stage | Base A&B (mL/L) | Key Additives |
|---|---|---|
| Cuttings / Seedlings | 0.65 | Roots Excel 0.3 | Drip Clean 0.1 |
| Veg Week 1 | 1.45 | Amino 0.8 | Multizyme 1.0 |
| Veg Week 2 | 1.60 | Nitrogen 1.0 (optional) |
| Flower Week 1 | 1.72 | Bud-XL 1.0 |
| Flower Week 2 | 1.98 | Bud-XL 1.0 |
| Flower Week 3 | 2.25 | Bud-XL 1.0 |
| Flower Week 4 | 2.50 | Top Booster 1.5 |
| Flower Week 5 | 2.38 | Shooting Powder 0.65 or Top Shooter 0.75 |
| Flower Week 6 | 1.98 | Shooting Powder 1.3 or Top Shooter 1.5 |
| Flower Week 7 | 1.98 | Begin flush (plain water + Drip Clean 0.1 optional) |

Mixing Protocol & Best Practices
- Source water check: Record starting EC & pH (H&G assumes near-zero EC RO).
- Add Part A → stir → Part B → stir. Never combine concentrates undiluted.
- Hit EC target by adjusting with base (up) or water (down).
- Additives in order: Drip Clean → Roots Excel → other liquids → dissolved powders.
- Final pH targets: Hydro 5.5-6.0 | Aqua Flakes/Cocos 5.6-6.2 | Soil 5.8-6.5.
Pro Tip: Running auto-dosers? Pre-dilute Roots Excel and Top Shooter to avoid micro-precipitation.
Troubleshooting the House & Garden Feed Schedule
| Symptom | Likely Cause | Fast Fix |
|---|---|---|
| Drippers clog, EC drifts up | Salt precipitation | Increase Drip Clean to 0.15 mL/L for one feed, then resume 0.10. |
| Pale new growth mid-veg | N deficiency or high pH | Re-calibrate pH pen; foliar 0.5 mL/L Nitrogen Boost. |
| Leaf tip burn during the PK-booster phase | PK overload | Skip Shooting Powder this run; flush 3-5 days at 0.5 EC. |
FAQ
What EC & pH Targets Work Best With RO Water?
Record the starting EC of your RO water, then use the Base A&B values in the feed chart and the medium-specific final pH targets listed under Mixing Protocol & Best Practices.
Can I Use Shooting Powder and Top Shooter Together?
No—pick one. Both are powerful PK spikes; stacking them risks tip burn and lockout.
How Long Should I Flush With House & Garden Nutrients?
Seven days of plain water is plenty when Drip Clean is dosed each feed. In coco, five days can suffice.
Do I Need Cal-Mag With Aqua Flakes in Soft Water Areas?
This guide treats Aqua Flakes as the base option formulated with Ca and Mg for RO or soft water. Check the Aqua Flakes product directions and your source-water conditions before adding a separate Cal-Mag product.
How Do I Avoid Dripper Clogging in Coco?
Use Drip Clean as directed in the feeding program, keep irrigation lines clean, and maintain appropriate solution conditions. If clogging or rising EC has already occurred, use the corrective guidance in the troubleshooting table above.
