Canna Nutrients COGr Board, 1 Meter

COGr Board Preparation

• 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 CANNA COGr Buffer Agent.The boards will increase in volume, see (2).
• Dilute the COGr 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 COGr buffering agent has been added, depending on which system you use, see (4).
• Leave the COGr in the COGr buffering agent for 24 hours to allow for total conditioning. Allow the excess moisture to drain from the slab and then make holes forthe plant, see (5).

COGr Board Planting

• The COGr is now ready to be planted, see (1).
• As soon as the plants are in the slab, we recommend that you use CANNA 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. It can be administered using a watering-can or a drip irrigation system, see (2).
• Start with COGr Vega with an EC of 1.5 mS/cm2, pH 5.5-5.8. See (3).
• Once the plants have developed a good root structure, the dilution should be raised to 1:250. Recommended EC:1.8-2.4 mS/cm2, depending on the quality of the water and its EC.

COGr Board Flowering Period

• Use COGr Vega up to and including the first 2-3 weeks of the 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 can be supplied by adding CANNA PK 13/14 for one week, 3 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.

COGr Board 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
• Rinse the COGr granulate thoroughly with a double dose of CANNAZYM and allow it to rest for 24 hours
• Buffer Agent is no longer necessary, so you can begin planting immediately

Irrigation
The guideline for full grown plants is 4-6 liters/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.
