Best Hydroponic Nutrients UK 2025: What Growers Actually Ordered

Athena, unmoved at the top. Two years running, clear of second place on both charts. It's a short, simple line - Core, Grow, Bloom, a Stack and not much else to get wrong - and it has an enormous amount of grower content behind it. When people don't want to think about feeding, they buy the line that's hardest to mess up. At this rate we're just going to laminate the chart.

The top three didn't budge at all. Athena, Advanced Nutrients, CANNA - identical to 2024. That's less boring than it sounds: it means the brands people commit to, they stay committed to. Nutrients are a habit, not a purchase.

Athena vs CANNA, since you keep asking. Athena outsells CANNA online by a comfortable margin on both charts - but flip to counter sales and CANNA wins outright. Read that as two different customers rather than a verdict: Athena is what people research and order online, CANNA is what people have always picked up in person. Both are excellent. Neither is going anywhere.

Hydroponic Research up four, the biggest climb in the national table. Our best guess is powder. Veg+Bloom is concentrated dry feed, so you're not paying to ship water around the country, and with everyone watching costs that maths has got very persuasive.

FloraFlex up five. That'll be the system dragging the feed along with it. Once you've bought into the FloraFlex ecosystem - caps, matrix, quick fills - adding their nutrients to the basket is the path of least resistance.

BioBizz down five. The one genuine faller near the top. Organic soil growing has been squeezed from both sides: cheap coco-and-mineral on one, and living-soil brands on the other. Worth saying the range itself is as good as it ever was - this looks like the category moving, not the brand slipping.

BAC jumps from 8th to 5th when you count bottles. Fewer customers, much fuller baskets. BAC is a full organic programme rather than a single hero bottle, so people don't buy one - they buy the whole shelf.

Hydroponic Research climbs six. Same powder story, but louder. When a brand rises faster on bottles than on buyers, it's usually because the people using it are running bigger rooms.

Athena's lead narrows on this chart. Advanced Nutrients is much closer here than on the popularity table, which tells you the AN buyers are deep in a multi-bottle programme - Big Bud, Bud Candy, Overdrive, the lot. Athena wins on how many people; AN closes the gap on how much they carry home.

The biggest single move in the whole article is in London. House & Garden has gone from the back of the pack to top of the capital - a thirteen place jump. Meanwhile CANNA, which won London in 2024, has fallen clean out of the top eight. London does not do loyalty.

London still refuses to follow the national table. The country's number one brand doesn't top the capital, same as last year. Plagron punches far above its national weight here too, and the whole chart is bunched - no runaway leader, just eight brands elbowing each other.

Terra Aquatica has been dethroned in Liverpool. Last year we wrote it up as the surprise story of the rankings - it had doubled everyone in that city. This year it isn't in Liverpool's top eight at all. Brutal. Sometimes a chart is one very enthusiastic customer, and we'd rather say that than pretend otherwise.

Manchester is still a FloraFlex town, even losing top spot to CANNA. It's the only city where the system brand ranks that high - somewhere in Greater Manchester there's a very committed household getting through an unreasonable quantity of quick fills. Respect.

Liverpool's chart is so tight it's less a league table and more a group hug. Top four separated by almost nothing, and five of the eight are brand new to the city's table.

Clonex is untouchable, and it isn't close. More growers ordered a Clonex product than any add-on brand going - a 50ml tube of Clonex rooting gel outsold entire nutrient ranges on customer count. It's been the default rooting gel for decades, it costs less than a takeaway, and nobody has ever finished a tube and thought "I'll try something else." Browse the rest of the propagation and cloning range if you fancy a change, but you won't.

Root inoculants have gone properly mainstream. Plant Success up three into second, with Psycho Myco also in the top ten. Five years ago mycorrhizae was a curiosity; now it's on the shopping list next to the cal-mag.

Silica is the additive story of the year - but the crown changed hands. Grow Genius and Power Si sell essentially the same thing, and Power Si has dropped three places while Grow Genius holds the higher spot. Mono-silicic acid has gone from exotic to competitive, and when two products do the same job, price starts doing the talking.

Grenade and Plant Life arrive from nowhere. Both brand new to the table. Worth watching next year - new entrants either double or vanish, there's rarely an in-between.

It is a dead heat. Once every comped and free bottle is stripped out, Flower Bomb and OG Rapid finish 2025 exactly level on customers - you could not get a cigarette paper between them. Given OG Rapid was one of our three best-selling bottles of 2024 outright, hauling it back to a tie is a serious year of work by the newer brand. Ask us again in twelve months.

Now flip it to bottles sold and the table detonates. Fruit Machine sits sixth on customers but goes straight to number one on units - a handful of buyers taking an enormous amount of stock. That's trade, not hobby growers. Eleven orders, ninety-odd bottles. Either someone's running a very big room, or there's a Fruit Machine appreciation society we've not been invited to.

The rest of the table barely moved. Positions three through six are identical to 2024. This is a category where people find one that works and stop shopping.
