It can be done: an organic fertiliser that fully meets RHP's strict requirements. REKA's Vidi Funda and Vidi FunCal have been awarded RHP certification, independent proof that both products meet RHP's quality and safety standards.
About RHP
Founded in 1963, RHP is the European knowledge centre for substrates and a trusted quality mark in Dutch and Belgian horticulture, monitoring growing media from raw material to delivery at the grower.
"We're pleased that Vidi Funda and Vidi FunCal now meet RHP's quality standards. It means substrate suppliers can blend them into growing media with the assurance of an independent quality mark, and it makes it easier for growers to include an organic fertilizer in their substrate," says Aron Oosthoek, Commercial Director at REKA.
About Vidi Funda and Vidi FunCal
Soil life first, steady nutrition
Restoring soil life is at the heart of everything REKA does, and Vidi Funda and Vidi FunCal are built around it. Both products are made from natural plant-based and marine raw materials, supplemented with natural sources of phosphorus and potassium. Vidi FunCal also contains extra calcium for a more resilient crop. Both products activate soil life, visible as fungal growth around the granules, and promote a healthy fungal-to-bacterial balance while improving soil structure and water-holding capacity.
Even, controlled release
What sets Vidi Funda and Vidi FunCal apart from other organic alternatives on the market is how they release their nutrients. Both products release nitrogen and calcium in a regulated, gradual way throughout the entire release period, so the crop receives a continuous, stable supply of nutrients.

Proven in trials
Trials show a clear increase in microbial and fungal biomass. Multiple cultivation trials also show that mineral fertiliser input, particularly nitrate, can be significantly reduced without any loss of yield, and often with better results.

Trial by NovaCropControl (2020), strawberry variety Arabella, grown on tabletops in a tunnel. Conventional fertilisation vs. Vidi Funda + calcium granules. Soil life measured by Eurofins using PLFA analysis.

Greenhouse trial at Hoogsewetering strawberry nursery (2022), variety Malling Centenary. All treatments followed the same mineral fertigation schedule with reduced nitrate. Total weekly nitrogen and calcium input was kept equal across all treatments, so the only difference was the fertiliser used. Compared: CRF + calcium granules, Vidi Funda + calcium granules, and Vidi FunCal.
What this means for growers
Growers can now have Vidi Funda and Vidi FunCal blended into their substrate as RHP-certified organic fertilisers.
For crops with a higher calcium demand, Vidi FunCal provides a controlled, long-lasting calcium supply.
