Growth Technology
The pH bench standard.
The pH kit most UK growers calibrate with, the Ionic feeds, and the Focus range for houseplants and citrus.
Nothing matches all of those filters.
Base feeds
The staple. Everything else goes on top of this.
Flowering boosters
Used through the second half of the cycle.
Cal-Mag and pH control
Correcting the water before the feed goes in.
Enzymes and additives
Everything that is not a base feed or a booster.
Propagation and starters
Mild feeds for seedlings and cuttings.
Accessories and spares
Replacements and fittings, kept out of the way of the main range.
Growth Technology, Ionic and Focus
Growth Technology make three quite different things, and most UK growers own at least one of them without necessarily connecting them to the same company.
The pH range is the one nearly everyone has: pH Up, pH Down in 81% and 30% strengths, Buffer 4 and Buffer 7 calibration solutions, and the probe cleaning and storage solutions that keep a meter reading accurately. A meter is only as good as its last calibration, and probes stored dry are the most common cause of drift.
Ionic is the nutrient line — one-part feeds for Hydro, Coco and Soil in hard and soft water versions. One-part feeds are simpler to dose and harder to get wrong than an A and B, which is why they suit growers running several small rooms.
Formulex is the seedling and cutting feed the trade has used for decades, mild enough for propagation and useful for rooting cuttings.
The Focus range covers houseplants — orchids, cacti, citrus, roses, olives and bonsai — with feeds matched to each rather than a single all-purpose bottle.

Growth Technology — simple British one-bottle feeds
Growth Technology keeps things straightforward with Ionic, a one-bottle-per-stage feed that skips the two-part mixing most other brands require — useful if you want fewer variables to get wrong on a first grow. Formulex is their dedicated propagation and first-feed formula, gentle enough for seedlings and fresh cuttings from day one, and Clonex — both the Rooting Gel and the Mist — is the industry-standard cutting aid used across brands, not just with Growth Technology's own feeds.
Liquid Silicon strengthens cell walls and is worth running from early veg through to late flower regardless of which base feed you're on, and Buffer 4 and Buffer 7 calibration solutions keep a digital pH pen accurate — recalibrate every two to four weeks for reliable readings. Liquid Oxygen boosts dissolved oxygen in reservoirs, useful for hydro and DWC setups where root zones can otherwise run low.
Clonex works as a stand-alone purchase even if you're running a completely different brand's feeding schedule — it's the one product here most growers buy regardless of what else is in their cupboard, and it's rare to find a UK grow shop that doesn't stock it somewhere on the shelf.
