Very happy with outcome when using on tomato seeds. Plants grew quick and strong. Plenty in the bottles so will last a long time. A great replacement for a brand I once used but is no longer in stock. Took a gamble on this and glad I did.

I’ve been growing a range of plants in my hydroponic setup, mostly lettuce, kale, and spinach, and after switching to these nutrients, I’ve seen a huge improvement in growth and overall plant health. Everything in my setup stayed the same: lights, trays, timer, etc, so this was a fair comparison, and the difference was clear. My plants are growing faster, look more vibrant, and seem much healthier than when I was using the smaller bottle of nutrients that came with my kit. The cos lettuce (same seeds) also 'stronger' if thats possible!
These bottles are also great value for the volume you get. It’s easy to see why they come up as an Amazon recommendation. I didn’t realise how much of a difference nutrient quality could make until now.
I’ve attached a photo of my current setup (at about 4 weeks) so you can see the results for yourself. This is only half grown, I have run out of room. I think they are growing about 30% faster. Highly recommend this if you’re serious about getting better growth from your hydro system.
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.
Choose the guide, enter litres, and we’ll calculate how many ml of Part A and Part B to add (per litre).
