Growth Technology

One brand, five different jobs

Growth Technology is unusual among nutrient companies in how wide it casts. The same catalogue carries a cloning gel most growers know by name, a crop-specific feed range aimed at orchids and chillies as readily as at indoor gardens, two full hydroponic base lines, and the single-element bottles you reach for when one number is off. That breadth is why this page runs to more than seventy buyable products.

Clonex and propagation

Clonex Purple rooting gel is the product the brand is best known for, sold here in 50mL, 250mL and 1L, alongside Clonex Cloning Solution in sizes to 5L. Rootzone in 250mL and 1L covers the root-drench side, and both turn up bundled in the GT Starter Kit with Foliage Focus. Cuttings work is one of the few places where a named brand genuinely is the default.

The Focus range

Focus is crop-specific rather than stage-specific — a different formulation per plant type instead of a grow and bloom pair. Foliage Focus is the flagship, with Orchid Focus in Grow, Bloom and General, plus Chilli, Herb, Vegetable, Fruit, Rose and Australian Native Focus. Complete Focus runs from 250mL to 20L for anyone wanting one bottle across the board. It is the range to point a customer at when they are not growing indoors at all.

Base nutrients and elements

Ionic. Single-part Grow and Bloom in 1L, 5.5L and 20L — the simplest way to run a reservoir, no A and B to balance.

Two-part. Optimum Grow and Bloom A&B, and Coco Grow and Bloom A&B for coco substrates.

Single elements. Liquid Nitrogen, Phosphorus, Potash, Iron and Trace Elements in 250mL, 1L and 5L, plus Liquid Calcium/Magnesium/Nitrogen. These fix a specific deficiency rather than feeding the whole plant — worth stocking once you can read what a leaf is telling you.

Extras. GT Silica, Super PK, Fulvic in 1L to 20L, and GT Foliar Spray supplied with a sprayer in 500mL and 5.5L.

Calibration

Growth Technology also makes the pH buffers we sell for meter calibration — pH 4 and pH 7 in 250mL and 1L, and a combined pH Calibration Kit. If you run a pH pen, this is where the consumables come from. The full range sits in pH Buffers & Aids, alongside the pH meters themselves.
