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.
