Subtil

Ensuring the correct amount of the right nutrients is not an easy task. Common practice is to use straight fertilizers. For smaller surfaces, straight fertilizers are not always practical. We offer an alternative with our NPK fertilizers which are fine-tuned to match the needs of substrate cultures.

Excess or shortage of plant nutrients often results into production and quality losses. Grogreen Subtil offers a convenient and foolproof solution to fertilize substrate grown crops.
