Growth Technology

UGro Pure Superior

UGro Pure SUPERIOR is a 50-litre bag (±5%) of fine coco fibre enriched with bat guano, endomycorrhizas, perlite and worm humus.

Our best mix just got even better with the introduction of the new UGro Pure SUPERIOR. Besides the guano, perlite and humus, our coco is now also mixed with endomycorrhizas. This fungus works in a symbiotic association with the plants to provide them with extra nutrients and moisture through the extension of their root system. All together these natural ingredients play an essential role in providing the perfect growing conditions for plants.


Advantages of UGro Pure SUPERIOR:
  • Start growing immediately! No need of added fertilizers during the first couple of weeks. It’s all in the bag. And it’s all natural.
  • Crops will benefit from all the natural properties of this mix. Ideal for fertilization, stimulation and protection.
  • It offers the roots a better uptake of water and nutrients, resulting in healthier plants.
  • It improves the plants ability to tolerate stress, disease and pests.

UGro offers two types of structures, UGro Standard and UGro Mix3, created for all types of cultures and with no variation in its quality. Both structures have a low EC level and a buffer effect that helps achieve an optimal absorption while keeping the pH stable.


UGro Standard (Plug, Small, XL, Cube and Pure)

  • Made of coco peat in small particles with a low percentage of fibres. It has excellent properties of air and water retention.
  • Low watering frequency.
  • Very high volumetric performance : 1kg of substrate can produce up to 15 litres of hydrated coco.
  • Recommended for short-term/seasonal crops such as tomatoes, cucumbers and peppers.



UGro Mix3 (Pot and Slab)

  • Made of 40% of coco peat, 30% of 10cm long fibres and 30% of chips of a maximum size of 1 inch. It has a lower water retention but a greater air retention, leading to better roots respiration.
  • Higher watering frequency than the UGro Standard due to a better drainage and less water retention.
  • Lower volumetric performance than the Standard structure : 1kg of substrate only produces 13 litres of hydrated coco.
  • Long lifespan. It can be reuse for a greater amount of cultures.
  • Recommended for long-term/permanent crops, such as gerbera or roses.
