Trusted by commercial growers: developed by hydroponic farmers with over 20 years of experience.
Complete two-part nutrition: essential macro and micronutrients supplied across two bottles.
Even, healthy growth: nutrients spread through the reservoir so every plant receives a consistent feed.
Stronger roots and stems: balanced nutrients help plants build healthy roots and sturdy growth.
Greener leaves: readily available nutrients support lush, healthy foliage.
From growth to harvest: supports plants through leafy growth, flowering and fruiting.
100% water-soluble: dissolves fully for clean, efficient feeding.
Kept in two parts for a reason: calcium is separated so it stays available to your plants.
Hydroponics, pots and garden beds: the same two bottles feed systems, containers and soil.

Mixing rates
Correct mixing order
1Add water to your reservoir or watering container first.
2Add Part A at the correct rate and mix thoroughly into the water.
3Add Part B only after Part A is fully dispersed, then mix again.
4Apply the finished nutrient solution to your hydroponic system, pots or garden.
Always dilute Part A and Part B separately in water. Never mix the concentrates together.
Part A and Part B are kept separate so the concentrated nutrients remain stable until they are diluted in water.
Yes. Use the Hydroponics & Seedlings rate of 3 mL Part A + 3 mL Part B per 1L of water.
Yes. Use 4 mL Part A + 4 mL Part B per 1L of water.

I've got lettuce and some herbs I like to grow in my indoor hydroponic setup and the growth I've had with this fertiliser is like there magic in it, the lettuce is growing so big and fast.
It dissolves cleanly aswell, and the results speak for themselves
High recommend this product, definitely will be buying again :)
I have a quite abit of coco peat bags in which i grow alot of my fruit and herbs in, ive been using other fertiliser for a little while and i always just thought i was doing something wrong because i never quite got a good yield from it.
Until i switched the the hydro A and B from completegrow it dissolve cleanly so there no residue left behind, and the yield ive been getting is really just shocked me, ive been able to grow much better, now that im using an fertiliser with actual fertiliser in it!
I've got a green house where I do alot of kitchen home gardening, so much better growing at home! Anyway this fertiliser has really upped my game, has made growing and feeding so easy, I've struggled in the past with bad slow growth, yellow leaves with other store bought fertilisers. Really good product! Can't recommend enough!
Hydroponic Precision Feeding
Eliminate the variables that hold your harvest back. eGrow A&B delivers 100% solubility and pH stability, ensuring your plants get exactly what they need, every single time
Accelerated Growth for Cleaner, Crisper Greens.
A strong fit for fast-growing leafy crops produced in hydro systems where clean nutrient delivery, even growth and easy repeatability are essential.
Maximum Output for Heavy-Feeding Crops.
Well suited to hydroponic tomatoes, capsicum, cucumber and similar crops where nutrient control, crop consistency and performance through active growth matter.
Designed for reliable herb production in hydro and indoor systems.
Ideal for growers producing basil, mint, parsley and coriander in controlled environments where stable feeding and clean reservoir mixing are important.
A strong choice for growers using coco, perlite and inert blends.
Built for growers who want hydro-style control in coco or inert media systems where complete nutrient delivery and consistent mixing are essential.
Seamless Performance in DWC, NFT & More.
Useful across a range of hydro setups where precise nutrient delivery, reliable dilution and repeatable crop feeding schedules are the priority.
Commercial-Scale Consistency & High Output.
A professional option for greenhouse, indoor and commercial-style growers who want dependable two-part nutrition for repeatable crop performance.
For peak performance, ensure your reservoir pH remains between 5.8–6.2. Our chelated formula is designed to stay stable, reducing the need for constant adjustments.
Choose the guide, enter litres, and we’ll calculate how many ml of Part A and Part B to add (per litre).

NPK 25-6-40 is a hydroponic nutrient profile with higher N and K for fast vegetative growth, leaf colour, turgor and yield quality—plus sufficient P to build roots and structure. Ideal for leafy greens, herbs, fruiting crops and general “grow” phases in DWC, NFT, flood & drain, coco and soil.
In hydroponics, plants receive nutrition directly from the solution, so the NPK balance matters. With 25-6-40, nitrogen (N) supports chlorophyll production and leafy biomass; phosphorus (P) underpins root growth, energy transfer and early flowering signals; potassium (K) regulates water movement, enzyme activity and fruit quality. The elevated K in this profile helps strengthen stems, enhance colour and flavour and improve overall stress tolerance.
Our professional blends use high-purity salts such as Calcium Nitrate, Potassium Nitrate, Magnesium sources and chelated trace elements (Fe, Mn, Zn, Cu, B, Mo) for stability and availability. A two-part (A & B) format keeps calcium separate from phosphates/sulphates until diluted, preventing cloudy precipitates and keeping EC/ppm predictable.
