Growth Technology Formulex — Complete Nutrient Solution for Seedlings, Cuttings & Young Plants
Best for: Growers propagating seedlings and cuttings who want a single, straightforward nutrient solution that actually works
Our thoughts
Formulex is the real deal for early-stage growing. It's been the industry standard for propagation for good reason — complete nutrition in one bottle, pH-sorted out of the box, and it works across soil, hydro, and foliar feeding. One we recommend constantly for growers starting out or scaling up their propagation game.
Growth Technology Formulex is a complete 1-part nutrient solution designed specifically for seedlings, cuttings, transplants, and young plants. It was the first formulation ever to deliver a full nutrient profile — nitrogen, phosphorus, potassium, calcium, and all essential micronutrients — in a single container. No mixing, no guessing, no unnecessary complexity. The concentrate is potent (makes up to 100 times its volume), pH-buffered to 6.0 with tapwater, and works reliably across hydroponic systems, soil grows, coco, and even as a foliar spray. This is why professionals and hobby growers alike have relied on it for decades.
How it compares
Formulex sits in its own category — a complete nutrient solution for early-stage plants, not a rooting hormone.
- Unlike rooting gels or powders, Formulex feeds young plants after rooting has begun
- Single-solution simplicity vs. multi-part nutrient systems that require mixing and separate bottles
- pH-buffered, so no need for adjustment with most tapwater
- Cost-effective concentrate format — one bottle covers hundreds of feeds
- Works across multiple mediums (soil, hydro, coco, foliar) without reformulation
Usage guidance
Formulex is straightforward to use. Dosing depends on your setup:
Soil growing
Add 5ml per litre of water, mix well. Use once weekly or as required.
Hydroponic systems
Add 10ml per litre of reservoir water, mix thoroughly. Use at every reservoir change.
Rockwool and propagation plugs
Use 1.5–2ml per litre for watering Jiffys and rockwool. Light feed to support early rooting without burning delicate growth.
Foliar feeding
Add 5ml per litre and spray directly onto foliage. Works well for supporting young plants between root feeds.
Start light — Formulex is designed for early-stage plants, so don't overfeed. Once plants are established and moving into vegetative growth, transition to a stronger veg feed.

Our take
Formulex is the straightforward choice for early-stage growing. Complete nutrition, pH-sorted, no mixing headaches, and proven to work across every system you're likely to use. It's cost-effective concentrate that goes a long way, and the fact that it's been the industry standard for decades tells you everything you need to know.
If you're setting up a propagation area or scaling up your cutting production, worth picking up while stock lasts. Does exactly what it should, day in, day out.
