House & Garden Aqua Flakes (1L / 5L / 20L)

What is House & Garden Aqua Flakes and how does it work?

House & Garden Aqua Flakes is a 2-part base nutrient designed for hydroponic systems. Part A and Part B are used in equal amounts to provide complete nutrition from veg through flower. Always use both parts—never one alone.

How do I mix House & Garden Aqua Flakes correctly?

Start with water, add Part A and mix well, then add Part B. Never mix the concentrates together undiluted. Shake both bottles before use. Mix gently to avoid foaming, and adjust pH after everything is added.

How much Aqua Flakes should I use per litre?

Typical dosage is 1–2.5 mL per litre of each part, depending on plant size and growth stage. Start with a low dose (e.g. 0.5–1 mL/L) for seedlings or when switching, and adjust based on EC readings and plant response.

What systems and media are best for Aqua Flakes?

Aqua Flakes is ideal for recirculating hydroponics like DWC, NFT, flood-and-drain, and aeroponics. It pairs well with inert media such as rockwool, LECA (clay), and growstones. It's not intended for soil, and coco users may prefer a coco-specific formula.

Can I use Aqua Flakes for both veg and bloom stages?

Yes—Aqua Flakes is a full-cycle base nutrient. You don’t need to switch to a separate bloom base; just adjust dosage and optionally add bloom boosters later in the cycle.

What’s the best EC and pH range for Aqua Flakes?

Most growers run Aqua Flakes between EC 1.2–2.0 depending on stage. For pH, aim between 5.5–6.2, with 5.8 often being the sweet spot. Monitor EC and pH regularly, especially in recirculating systems.

Do I need to use Cal-Mag with Aqua Flakes?

It depends on your water source. RO or soft water may need Cal-Mag support. Hard tap water often has enough, but always check your starting EC and monitor plant behavior to avoid deficiencies or imbalances.

Can I use additives with Aqua Flakes?

Yes—it's compatible with silica, enzymes, beneficial microbes, and H&G additives like Roots Excelurator and Top Shooter. Just add silica to plain water first, then Aqua Flakes. Don’t overload the system—start light with any additive stack.

Is Aqua Flakes clean for hydro gear?

Yes—it’s low-residue and designed for clean hydro use, but your system hygiene, EC levels, and reservoir temps all play a role. Use Drip Clean if clogging is a concern, and flush regularly in high-demand systems.

Why do my plants show deficiencies or issues on Aqua Flakes?

Most issues come from pH drift, high EC, root stress, or overstacking additives—not the nutrient itself. Check your pH and EC first before increasing feed strength. Clean systems and stable res temps are key.

Can Aqua Flakes be stored mixed in a reservoir?

Yes, short-term. Keep the reservoir cool, circulate it gently, and monitor pH drift. Fresh mixes are ideal, but stored solutions can work if maintained properly. Recheck pH before each use.

Is Aqua Flakes suitable for edible crops and indoor grows?

Yes—Aqua Flakes is widely used for herbs, fruits, vegetables, and flowering plants in indoor hydro setups. Follow proper hygiene and avoid foliar spraying near harvest on edibles.

Can I switch to Aqua Flakes mid-grow?

Yes, but transition carefully. Start with a slightly lower EC than your current feed, monitor plant response for 3–5 days, then ramp up if needed. Sudden switches at full strength can cause stress.

What’s the most common mistake with Aqua Flakes?

Mixing Part A and B concentrates together, feeding too strong too early, or assuming it’s “set and forget.” Always check pH and EC, especially in hydro where balance is everything.
