CANNA COGr Boards

After years of research, CANNA introduces a new and revolutionary coconut product: CANNA COGR.
  • This product consists of a sophisticated mix of coconut grit, coconut fiber, and coconut granulates.
  • Thanks to the coarse coconut structure, COGR has the unique property of being able to absorb large amounts of nutrients, moisture and air simultaneously, which are made immediately available to the plant.
  • This makes the medium superior to all other growing media, promoting faster root development and higher yields.

Follow the instructions given below carefully; convince yourself of the superior properties of this top quality, professional product.

CANNA COGr Boards

Directions of Use

  • COGR boards are pressed and delivered dry, which facilitates transportation and storage, see (1).
  • In order to prepare them for use, the COGR boards must first be soaked and buffered in the specially prepared COGR BUFFER AGENT. The boards will increase in volume from 3 litres to 17 litres of top quality substrate, see (2).
  • Dilute the BUFFERING AGENT with water in the ratio 1:500 and adjust the pH to 5.5-5.8.
  • Add ± 12.5 litres of diluted buffering liquid per COGR board,using a watering can or hose, see (3).
  • Drainage slits are made either before or after the BUFFERINGAGENT has been added, depending on which system you use, see (4).
  • Leave the COGR in the BUFFERING AGENT for 24 hours to allow for total conditioning. Allow the excess moisture to drain from the slab and then make holes for the plant, see (5).

  • The COGR is now ready to be planted, see (1).
  • As soon as the cuttings are in the slab, we recommend that you use RHIZOTONIC. This stimulates root growth and facilitates rooting within the slab. More vigorous plans are formed, yielding a more productive plant. RHIZOTONIC can be added by spraying the leaves, using a watering-can or a drip irrigation system, see (2).
  • Start with COGR VEGA with an EC of1.5 mS/cm2, pH 5.5-5.8. See (3).
  • Once the plants have developed a good root structure, the EC should beraised to 1:250. Recommended EC:1.8-2.4 mS/cm2, depending on the quality of the water and its EC.

  • Use COGR VEGA up to and including the first 2-3 weeks ofthe flowering period (12 hours light/darkness). Once growth has peaked and flower formation begins, it is time to start using COGR FLORES (dilution 1:250;EC 1.8-2.7 mS/cm2; pH 5.5-5.8). See (1).
  • During flowering, the plant needs more phosphate and potassium which canbe supplied by adding PK 13/14 for one week, four weeks before harvesting. Result: extra yield. see (2).
  • Stop giving COGR FLORES a week before harvesting.
  • Just give water and CANNAZYM during the last week.

Reuse

Due to its solid structure, COGR can be reused 3 times without any problems or quality loss.

  • Harvest the plant and remove the plant remains above soil level, see (1).
  • Rinse the COGR granulate thoroughly with a double dose of CANNAZYM and allow it to rest for 24 hours, see (2).
  • BUFFERING AGENT is no longer necessary, so you can begin planting immediately, see (3).

Irrigation

The guideline for full grown plants is 4-6 litres/m2 a day. The recommended number of drip feedings is 1 to 3 a day.Drip feeding should preferably take place during the daytime when the lamps are on. Provide sufficient drainage (10-20%). With tap water that has a high salt content (EC > 0.6 mS/cm2) the percentage drain should be increased to prevent salt accumulation.

Growing on COGr in pots

If you want to use COGr boards in pots, just simply buffer the slabs in the normal way and empty the contents out into pots. You can dilute a 1 Litre pack of COGr buffering agent to 500 Litres. A 2 litre pack of CANNA COGr nutrients (1 Litre A, 1 Litre B) make up 250 litres of full strength nutrient.

Tips

  • When cultivating in plant trays with a sealable drainage system, it is easier to begin by making the drainage incisions, then turning over the COGr and filling the plant container with the buffering solution.
  • Right from the start, you can add CANNAZYM to the feeding. CANNAZYM breaks down dead roots, provides more air in the slab, prevents plant diseases, stimulates the soil's micro-life and makes extra nutrients available to the roots. CANNAZYM can be given continuously with the feeding (dilution 1:400) or once a week(dilution 1:100). Furthermore, CANNAZYM increases the re-usage possibilities of the COGr.
