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 andadjust 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 toallow 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, werecommend 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 weekbefore harvesting.
• Just give water and CANNAZYM during the last week.
Reuse
Due to its solid structure, COGR can be reused 3 timeswithout any problems or quality loss.
- Harvest the plant and remove the plant remains abovesoil level, see (1).
- Rinse the COGR granulate thoroughly with a double doseof CANNAZYM and allow it to rest for 24 hours, see (2).
- BUFFERING AGENT is no longer necessary, so you canbegin planting immediately, see (3).
Irrigation
The guideline for full grown plants is 4-6 litres/m2 a day. Therecommended number of drip feedings is 1 to 3 a day.Drip feeding should preferably take place during thedaytime when the lamps are on. Provide sufficientdrainage (10-20%). With tap water that has a high saltcontent (EC > 0.6 mS/cm2) the percentage drain shouldbe increased to prevent salt accumulation.
• 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.
• Once the plants have been in the COGr for two weeks, it is recommended that CANNAZYM be added to the feeding. CANNAZYM breaks down dead roots, provides more air in the slab, prevents plant diseases, stimulates the soil's microlife 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.
