CANNA COGr Board 100x15x7,5 cm

The COGr mats are the heart of the COGr series. The mats consist of a sophisticated mixture of coco flakes, coco fibres and coco granules. CANNA COGr Buffer Agent is needed for swelling as it is not buffered. The pH value should be around 5.8, substrate is not pre-fertilised. One COGr mat yields 21 to 25 litres of uncompressed coco.

Advantages of the CANNA COGr mats:

Thanks to the coarse structure, COGr mats have unique properties of absorbing large amounts of nutrients, moisture and air simultaneously, which are immediately available to the plant.
These properties make the medium superior to all other substrates in terms of faster root development and higher yields.
COGr mats are ideal for transport. They are supplied in dry and compressed form. They weigh only 2 kilograms.

Reuse

Due to its robustness, COGr coco substrate is ideal to be reused up to three times without losing quality.

• Harvest the plants and remove the plant debris on the surface
• Rinse the COGr mat thoroughly with a double dose of CANNAZYM and leave it to soak for 24 hours
• Now you can grow again without the need for buffering

Growing on COGr in pots

If you want to use COGr mats in pots, moisten the mats in the normal way and empty the contents into the pots. The mixing ratio is 1 litre pack of COGr buffer substance to 500 litres. A 2 litre pack of CANNA COGr Vega A+B for the growth phase will give 250 litres of full strength nutrients. Finally, for the flowering phase, switch to CANNA COGr Flores A+B.

Tips

• When growing in plant trays with a sealable drainage system, it is easier to make drainage incisions, then turn the COGr plate upside down and fill the plant tray with the buffer solution.
• From the beginning you can add CANNAZYM to the plant food. CANNAZYM removes dead roots, allows more air into the mat, prevents plant diseases and stimulates microorganisms in the soil. In this way, the roots receive additional nutrients. CANNAZYM can be added continuously (mixing ratio 1:400) or once a week (mixing ratio 1:100). In addition, CANNAZYM increases the reuse possibilities of the COGr.
