How to use Growth Technology Formulex
Growth Technology Formulex is highly concentrated and designed for simplicity. Always shake the bottle well before use. It can be used from the moment your seedlings or cuttings require their first feed up until the point they are ready for a dedicated vegetative or flowering base nutrient.
Dosage Rates:
- Soil/Coco Cultivation (Standard Feed): Use 5ml per litre of feed water. Apply weekly as part of your regular watering schedule.
- Hydroponic Systems (Reservoir): Add 10ml per litre of reservoir water. Replenish or refresh your reservoir solution as required based on your system's needs.
- Foliar Feeding (Mist or Spray): Mix 5ml per litre of water. Spray plants top-to-bottom, ensuring the underside of the leaves are thoroughly covered. Use during low-light periods to prevent leaf burn.
- Soaking Propagation Media (Rockwool/Jiffy): Use 5ml per litre of water. Soak the media thoroughly before inserting your cuttings or seeds. Consider adding a few drops of GreenFuse Root for explosive root development.

Frequently Asked Questions
Is Formulex a complete, standalone nutrient?
Yes, Formulex is formulated as a complete, balanced, and stabilised solution containing all macro, secondary, and micro-nutrients. It is a true single-solution food for young plants, meaning no other base nutrients are required during the propagation and early vegetative stages.Do I need to check the pH of my water when using Formulex?
Formulex has a highly effective inbuilt pH buffering capacity. It is meticulously formulated to express a stable pH of approximately 6.0 when mixed with standard tap water, usually eliminating the need for external pH adjusters like Growth Technology pH Up.Can Formulex be used on plants in the flowering or fruiting stage?
While Formulex is highly versatile, it is best used only during the propagation and vegetative stages. For optimal results during the flowering or fruiting phases, you should transition your plants to a specialised high-PK base nutrient and boost regimen.How long does a single bottle of Formulex concentrate last?
Formulex is a highly concentrated formula. As a working solution, it will make up to 100 times its volume of feed, making it a highly cost-effective nutrient. A single litre bottle, for example, can produce 100-200 litres of ready-to-use solution, depending on the dosage applied.SKU: 1137Free delivery on orders over £60*
