Three 500 ml bottles and a sachet of Trichoderma for a complete organic growing cycle
This kit brings together everything you need for a complete organic grow in a single purchase, from the first watering through to harvest. It contains the organic growth fertiliser NPK 3-1-5 and the organic bloom fertiliser NPK 2-3-4, each in a 500 ml bottle, the flowers and fruits biostimulant in 500 ml, and a 10 g sachet of Trichoderma to inoculate the grow medium. All these products are of plant origin and approved for use in organic farming. You can get started straight away without having to piece together a programme from separately purchased products.
🧺 What the kit contains
Each bottle plays a specific role in the cycle. The grow formula supplies the nitrogen and potassium your plants need to build their stems and leaves, while the bloom formula shifts the balance between nitrogen and phosphorus as the first buds appear. The seaweed-based biostimulant is added from pre-flowering onwards, without increasing the fertiliser dose. Trichoderma, finally, is a beneficial fungus that colonises the root zone and sustains the microbial activity on which the uptake of an organic fertiliser depends. Instructions and a dosing chart are included with the bottles.
Growth, 500 ml
The NPK 3-1-5 fertiliser is dosed at 0.25 to 2 ml per litre, from first roots through to pre-flowering.
Floraison, 500 ml
The NPK 2-3-4 fertiliser takes over at 1 ml per litre during pre-flowering, then at 2 ml per litre.
Flowers and fruits, 500 ml
The biostimulant is added at 5 ml per litre, from pre-flowering through to fruit ripening.
Trichoderma, 10 g
The sachet treats 100 litres of solution or irrigation water, at 0.1 g per litre.
Complete the kit with a pH test
An organic fertiliser is only properly absorbed within the pH range where micro-organisms remain active, between 6.2 and 6.8. The liquid pH test kit allows you to check your irrigation water before each application. On coco fibre, the calcium magnesium supplement completes the programme at 1 ml per litre, as this grow medium retains calcium.
Keep the solution warm and well oxygenated
The fertilisers in this set are not pasteurised, and the micro-organisms that make them available to plants slow down noticeably below 15 °C. Aim for a solution and grow medium above 20 °C, and keep the solution circulating continuously in hydroponics using a pump and air stone cleaned regularly. Shake each bottle before use, add the products one at a time to the water, stirring between each addition, then rinse your measuring equipment.
The programme follows the plant's growth stages. At the first roots, start at 0.25 ml per litre of each fertiliser with 0.1 g per litre of Trichoderma, then move to 0.5 ml per litre at the first true leaves. At full growth, only the grow version is used, at 2 ml per litre. At pre-flowering, both fertilisers are applied at 1 ml per litre each alongside the biostimulant at 5 ml per litre, then the flowering version increases to 2 ml per litre through to fruit maturation.
These doses give an idea of what the kit covers. At 2 ml per litre, each bottle of fertiliser prepares 250 litres of solution, and the biostimulant prepares 100 litres at 5 ml per litre. That is enough for a complete cycle on a small raised-bed vegetable garden, a few tomato plants in pots, or a domestic hydroponic system. If you grow more, each product is also available separately in 1-litre bottles or 5-litre containers, and you can continue the same programme without changing your routine.
💧 Soil, coco or bioponic growing
The programme is the same in open ground, potting compost, coco fibre, and biological hydroponics. In open ground, two waterings per week at 0.5 ml per litre of each fertiliser, starting 2 weeks before planting, prepare the soil. With coco fibre, set the irrigation water to a pH of around 6.5. In bioponics, the solution must be kept moving and oxygenated; the system is started up 2 days before planting with 0.5 ml per litre of each fertiliser and the Trichoderma. Full details for each product can be found on the organic growth fertiliser product page.
🌿 A fully organic growing method
The three bottles and the Trichoderma are suitable for organic farming under regulations (EU) 2018/848 and 2021/1165. Both fertilisers are 100% plant-based, with no animal matter, and the biostimulant is an extract of Ascophyllum nodosum seaweed obtained by cold pressing. None of these products is classified as hazardous on its safety data sheet. You can therefore manage your vegetable plot or container plants without synthetic inputs, provided you correct the pH with a product that is also approved for organic use if your water requires it.
📏 Dimensions and storage
The fertilisers and biostimulant keep for 2 years after manufacture, stored upright between 5 and 30 °C, and the Trichoderma for 18 months, kept dry and between 5 and 25 °C in its sealed sachet. As these products have a shorter shelf life than mineral fertilisers, it is best to open the kit at the start of a growing season. It measures 23 x 16.9 x 7.7 cm, weighs 2.1 kg, and works out cheaper than buying its four components separately.
