Organic substrates
As the organic development increases with great leaps, healthy chemical free nutrition and sound growing systems that take the environment in consideration are demanded more and more by today’s consumer. Tref has followed the latest trends closely and invested heavily in organic bio-substrates making sure it has the ability to deliver the substrates today’s customers are demanding.
In the Organic Sector, the main issue at play is; ‘Getting available nutrition targets right!’ Especially herbs, grown in a very short period of time, need the right amount of available Nitrogen (N) at their disposal. Tref Organic substrates deliver the nitrogen exactly at the time it is needed by the crop.
Another break through is the fact that Tref, by eliminating animal fertilizers, a feeding source for black gnats, has succeeded to get rid of all black gnat related problems when growing, making use of Organic fertilizers.
The re-engineering of Tref ECO11PL fertilizer secures the availability of nutrition for short term Organic crops.
