House & Garden Aqua Flakes B, 1000 L

A Low-PPM Base Nutrient for Recirculating Hydroponic Systems, Part B 1000 L

Recirculating hydroponic systems — ebb and flow, deep water culture, aeroponics, and rockwool slabs on a recovery drain — are less forgiving of a heavy or unstable base nutrient than a run-to-waste setup, since the same solution keeps cycling past the roots instead of draining away after each feeding. House & Garden Aqua Flakes is a two-part, low-ppm base nutrient built for exactly that kind of recirculating use, with Part B formulated to be mixed in equal amounts with Part A rather than used on its own.

This 1000 L bottle of Part B is sized for a large commercial or industrial-scale hydroponic operation. Mix it in equal parts with Aqua Flakes Part A directly in the reservoir, never combining the two concentrates before they hit the water.

Key Features & Benefits

• Part B of a two-part system — formulated to be mixed in equal amounts with Aqua Flakes Part A
• Low-ppm formulation — built to suit recirculating systems, which are more sensitive to nutrient buildup than run-to-waste setups
• Suited to recirculating hydroponic systems — works with ebb and flow, DWC, aeroponics, and rockwool on a recovery drain
• Available in 1000 L — sized to match the scale of the operation using it

Who Should Use Aqua Flakes Part B

Growers running a recirculating hydroponic system — ebb and flow, DWC, aeroponics, or rockwool with a recovery drain — who need a low-ppm base nutrient will use Aqua Flakes Part B together with Part A as their core feeding program.

About House & Garden

House & Garden is a nutrient and additive brand established in 1990 by William Van De Zwaan, whose family had a background in Dutch horticultural glasshouse production; the company formulates its base nutrients and additives in small batches, filtering its process water through multi-stage ceramic filtration. Hydrofarm acquired House & Garden in 2021, and the brand's manufacturing and research operations are based in Humboldt County, California, building a product line of base nutrient systems and root, flowering, and growth additives sold to growers in dozens of countries.

Frequently Asked Questions

How do I mix Aqua Flakes Part A and Part B?

Add equal amounts of Part A and Part B directly to your reservoir water, mixing thoroughly between additions. Never combine the two concentrates together before they reach the water, since mixing them at full strength can cause nutrient lockout.

Can I use Part A or Part B on its own?

No. Aqua Flakes is formulated as a two-part system, and Part B is not a complete feed by itself — it needs to be used together with Part A in equal amounts to supply a full range of macro and trace elements.

What hydroponic systems is Aqua Flakes designed for?

It's built for recirculating hydroponic applications, including ebb and flow, deep water culture, aeroponics, and rockwool systems with a recovery drain. Its low-ppm formulation is suited to systems where the same nutrient solution cycles past the roots repeatedly rather than draining away.

How do I know how much to use?

Use an EC/PPM meter to measure your reservoir after mixing and adjust the amount of Aqua Flakes added until you reach your target nutrient strength for the current growth stage. Follow label directions for a starting dose, then fine-tune from there.

When should I adjust pH after mixing?

Mix both parts of Aqua Flakes into the reservoir first, then check and adjust pH afterward, since the nutrient solution itself will shift the water's starting pH. House & Garden recommends storing the concentrate between 7°C and 30°C to keep the formula stable before use.
