Growth Technology

UGro Pot9

UGro Pot9 is a flexible bag/pot, holding a 900-gram brick of dehydrated coco substrate, made of 40% of peat, 30% of fibres and 30% of chips. It has small punched holes in its base to facilitate drainage. The bag has been treated in order to achieve an excellent UV stability. With only 2 litre of water, it yields up to 9 litres of high quality coco peat.


Coco substrate is obtained by crushing and processing the outermost shell of the coconut and can be used as an alternative option to the more traditional substrates. It offers excellent water retention and airing properties that help the root system and the plant to grow faster. Being a sustainable and biodegradable organic matter means it also has natural trichodermas, a microorganism that fights root rot and stimulates the growth of plants.


Advantages of UGro Pot9:

• No pot needed! The bag has been designed to grow directly into it.

• It is convenient and easy to carry.

• It is suitable for all types of cultures, outdoors and indoors. Perfect for permanent crops.




All the products are washed in soft water, buffered and get natural trichodermas.

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.


Pot’s Profitability 

UGro Pot not only is convenient and saves you from buying a flowerpot, but it is also designed to achieve the highest profitability. Each bag has a specific size that allows to optimise the quantity of plants you can grow in a square metre. For example, Pot4 goes 49 times (7 rows of 7 bags) in 1 m2. Pot9, 25 times (5×5) and Pot60, 16 times (4×4). And they all are suitable for using indoors as well as outdoors.
